Batteries Are Not Created Equal

2009-03-03T20:00:00.001-08:00

Writen by Ruben Soliman

Once in the air of a long flight, the attendant informs the passengers that the "use of electronic devices is no longer prohibited". To pass the time, I decide to pull out my laptop to finish off some work. Normally, I like to use flights for catching up on some sleep, but today I wasn't feeling very tired. Relying on my laptop battery, that was fully charged the night before, I proceed to catch up on some overdue business. In this midst of one of my many thoughts, something far more tragic than an oxygen mask falling down happens... or at least more tragic at that moment... my laptop battery dies.

My first reaction was to look around for the nearest outlet, only to remember that I am on an airplane and airplanes do not have outlets. I try to reboot, hoping that it was simply a glitch of some sort, but no such luck. Now what? I am left staring at a blank screen with a powerless laptop. As I browse about the cabin, I notice that there are many other businessmen continuing to work on their laptops. One man in particular is using a similar laptop -- a model close to the powerless thing sitting in front of me. Why has his battery lasted longer than mine? Surely we have the same brand of battery, and I am pretty sure that mine is practically new. I sit there for a moment looking around with a baffled and confused look on my face. Now, I am left to endure the rest of this flight thinking of how I could have prevented this.

Of course I do realize that it was not the end of the world. My battery dying did not cause any serious damage. None the less, I was reminded of an important lesson. Always be prepared! One never knows what could happen next, so it is always good to have some types of back-up plan. When it comes to batteries, not all batteries are created equal. Some batteries will simply last longer than others. I have a few friends that like to store extra batteries in their refrigerator. I personally find this a bit extreme and silly, but they will swear that their batteries last longer. I don't know if this type of storage truly aids in longer life for the batteries, but I do know this. Life is unexpected and so are electronics. Next time, whether is it having extra batteries or not, I am going to do my best to be better prepared.

As an avid user of my laptop, I heavily rely on my battery to work when needed. When shopping for laptop batteries, I find that http://www.ebatteriestogo.com is a good source for all my battery needs.

Do you ever wonder how a cable modem works? Are you trying to understand if high-speed internet access is right for you? Would you like to know how to purchase a cable modem? Here are some cable modem FAQs that will give you more information.

What do cable modems do? A cable modem is a device that allows you to use your cable connection to get high-speed internet access. It is responsible for detecting and converting the data that eventually gets sent to your computer.

How do cable modems work? Since a coaxial cable has a high data storage capacity, both the internet and cable television can use the same cable. The cable modem takes a data signal and converts it to its digital form. This is the form that your computer reads and eventually converts into data that you can understand.

Where can you purchase a cable modem? You can get a cable modem from your cable company, from a store, online, or secondhand by searching in the classified ads.

How can you compare prices? There are plenty of websites devoted to price comparisons. You can also do the research yourself by looking at individual websites and asking questions at retail stores. Start a spreadsheet to keep track of the information. Once you find a few products that fit your requirements, you can do more in-depth research.

Can you read product reviews? Yes. There are a few ways to find product reviews. Companies offer testimonials as reviews. These opinions may be biased, however. If you want to see both good and bad reviews, you can find a variety of them online or in consumer magazines. You can also ask people in online forums to ask them what they think of a certain product.

These cable modem FAQs should help you make a purchase. Doing research is essential in getting the best product for your money.

Vertical server racks are manufactured to meet the specific needs of customers. They provide maximum storage in minimum floor space and make inventory control easier by allowing high visibility and easy recovery. They also offer easy access and safety of goods.

Aluminum racks and carbon compounds are the most suitable for any vertical server rack. Other composite materials and fiberglass can provide resistance to caustic chemicals, oils, and environmental extremes. Steel is used to provide maximum strength for heavy loads. If a rack is constructed with structural channel and 10-ga steel, it can provide a large 6,500-pound storage capacity per bay. Different models may be combined to form larger units as desired.

The main features of vertical server racks are hard items, which can be handled more easily; the provision for extra storage space; and the ease with which they are shipped, knocked down, and assembled. These racks are also friendly with any sized add-ons, supporting power strips. Powerful industrial-grade racks handle a variety of capacities. They also offer features such as waterproofing, fire resistance, chemical and corrosion resistance, and modularity and portability. Vertical storage rack systems can also provide spill-restraint features, automation (shelf rotation), open-wire racking (for air flow), and ESD (Electrostatic Discharge) protection.

The price of vertical server rack storage depends upon weight, dimensions, volume, environmental considerations, and safety features.

The vertical server rack storage system has evolved to meet the customer requirements of having a storage system that stores the server as well as all necessary sub-parts. This system is the best solution for industrial segments and assists businesses in finding ways to best utilize their existing space and improve productivity.

Wireless Network Trouble Shooting

1. Wireless Adapter First check to see if your wireless adapter is on and working properly. If you are using a PCMICA wireless adapter ensure that the card is pressed completely in. If the wireless adapter card was not plugged in when you started your laptop you may want to restart your computer for a fresh start. If you are using a laptop with a built in wireless adapter. What Wireless Network Check the bottom right hand task bar to see if you are connected to a wireless network. Many people are connected to the wrong wireless network with a weak signal or hardly any connectivity. You want to change your wireless adapter setting to choose Infrastructure access points only so you're not connecting to rogue wireless access points.

3. SSID and ME Next check your wireless settings for the following: DO you have the correct SSID typed in, is your encryption key typed in correctly, does your wireless router and wireless adapter have the same security settings.

4. DHCP ME If you don't have a manual TCP/IP address then your wireless router needs to have it's DHCP server turned on. Connected to your web interface and turn on your DHCP server. Next go to your wireless network icon in the bottom right hand corner and disable your wireless adapter and then enable it. This will renew your DHCP request to the routers DHCP server.

5. PING!- Next we will use a command line function called PING. Type "cmd" in the run box, this will bring up your DOS window. Now type in ping and then type in the TCP/IP addressof your default gateway. If you have not changed it your default gateway's ip address should be 192.168.1.1 or 192.168.0.1. If you receive a reply then you know that you are connected properly to your router.

6. WWWWHAT Now try and surf the web. Go to google.com or another simple page. If nothing comes up then you might have a manually configured IP address with the correct DNS servers entered. Connect to your wireless routers web interface and check the status. You are looking for the multiple DNS server IP address. Copy these IP addresses into you adapters TCP/IP settings and hit ok.

7. Google ME Once your DNS servers are entered you should be able to surf the net. If you still can't surf the net try restarting your computer and check you cables again to make sure you haven't missed something.

Flat Panel Monitors The Benefits Are Clear

2009-02-27T20:00:00.001-08:00

Writen by Ellis Pullman

For those questioning the hoopla surrounding flat panel monitor, it may be easiest to simply go to your nearest electronics store and check them out for yourself. That will be your ultimate selling point. However if you'd like to whet your appetite a bit prior to considering making purchasing decisions here are some benefits of flat panel monitors.

You generally get more viewable space for comparable cathode ray tube monitors (those cubish shaped monitors). Other tangible benefits of flat panel monitors is that they offer greater focus, convergence, geometry, configuration features, better resolution, greater high density dot pitch making things like even fonts super clear, and more. They simply outclass cathode ray tube monitors in every way.

For those who are involved with multimedia professionally such as image and graphics editing, or even if you use multimedia applications such as watching home movies and pictures, flat panels provide a crystal clear view that cathode ray monitors simply cannot provide.

Those are just some of the benefits, your best bet is to simply get your hands on some flat panel monitors on display and see if they are worth your while. Don't be surprised if you like countless others make the switch as you fall in love at first sight.

Electronic Document Management Why

2009-02-26T20:00:00.001-08:00

Writen by Kevin Calhoun

Irrespective of a company's size, most businesses have already adopted some sort of an electronic document management system, but they usually do not think of it in those terms. As a result, the system is often incomplete; it may include word processing, spreadsheets and a backup system for storage, but they rely on a number of manual paper document processes, as well. The documents may be distributed in a variety of ways, either by mail, fax, email or courier. The fact is that most companies already have a "hybrid" document management system consisting of paper and electronic documents which can be overcomplicated and include more costly manual processes than necessary. Any excessive expenses relating to documents are typically considered part of "the cost of doing business".

It is significant to note that these electronic systems were chosen because they increase productivity, and subsequently profits. But in this new age of technology, new tools are introduced on an almost monthly basis and many companies find they have acquired a variety of systems which have not integrated very well with one another. Of course, just to remain competitive and keep up with new trends, companies find they must continually research the newly emerging technologies and products, yet this can be overwhelming. So many variables must be considered, and often times executives may not be exactly sure how a new technology would be an advantage. It is at this point that some logical thinking might help, and the key question should be asked, "What is our goal?" The answer is usually, "Increase profits and streamline for the long-term".

It is essential that the goal is not forgotten when entertaining the thought of implementing new technologies, and it is likewise important to begin thinking in terms of enterprise document management because this title fully describes the concept of what was intended originally when the first computer was purchased. The concept of email, however, did not exist when that computer was initially bought, and as a result, it seems that the business world still forgets to include it today as an actual component of their document management systems. Yet each email message is, in itself, a document. A document is an instrument of communication. This instrument of communication requires a conduit or distribution mechanism, i.e., email system, just like other documents require fax, mail or an email system. Does it not make sense that the entire document creation, distribution and storage process be consolidated and managed simultaneously for maximum streamlining effect?

Because business document management needs have grown due to increased productivity following the advent of the computer, businesses have subsequently become reliant upon the computer. Most mid- and large-scale companies now employ their own IT staff, while the smaller companies outsource for their computer needs. The industry is enormous, and it is incredibly complicated and confusing to most business professionals born before 1970. Consequently, the prospect of analyzing the computer and document-related options for operational streamlining can cause most to suffer paralysis when it comes time to make a choice.

Meanwhile, even when a company is equipped with its own IT department, the staff is already working frantically just to keep up with the accelerating pace of business and the currently existing technology to deliver it. In essence, all businesses must attempt to balance their first line of business with the second and third lines: documents and technology. Upon coming to grips with this reality, three serious questions should be considered:

How much do Lines #2 and 3 cost just to maintain the first line of business?

How much more will be spent as all IT and document management costs rise?

How much more will it cost to increase profits and business with our present system, or with a better system?

"It's not as bad as it seems" Finding the answers to these questions can be challenging, but the payoff can be tremendous if approached realistically and with the anticipation of instituting a series of simple solutions to streamline business operations. When considering the current "cost of doing business" with a hybrid document management system, it makes sense to investigate what solutions are available and take advantage of any expertise available from consultants who specialize in examining processes and costs relating to documents. Many times, we need only to have our circumstances described in plain English and the various costs broken down into comprehensible categories before we feel comfortable in pursuing solutions. electronic document management consultant can also be helpful in presenting a series of recommendations with cost estimates which are likewise presented in plain English for business professionals rather than computer technology specialists.

"Full Integration can be affordable" Once again, what would a company's primary objective be in improving their total enterprise document management system? The answer, streamline for the long-term and increase profits. Sight of this goal should never be lost. When huge amounts of money and time have been invested in a hybrid system, it would make sense to consider retaining that initial investment and simply reinvest the dividends. Options may be available to retool an already existing system so that it performs at the highest potential. When possible, it could be suggested: adapt, don't scrap.

This message is especially significant for companies either facing the regulatory compliance issues mandated by the Sarbanes-Oxley Act, or those attempting to manage the mountain of paper documents fundamental to certain industries, such as lending or insurance. These issues frequently appear to be problems relating solely to document storage, but the actual difficulties may arise from an earlier stage in the document lifecycle. An expert in enterprise document management may be able to analyze the current systems and conclude that additional physical or electronic storage is not as necessary as a solution implemented in the creation or distribution stages of a document's life. Thus, while investigating remedies for document management or operational streamlining, it might be that you already have everything you need, but you just haven't discovered the right approach or tool to make it all work at maximum efficiency.

Some Things You Need To Know To Save Money On Inkjet Cartridges

2009-02-25T20:00:00.001-08:00

Writen by Gregg Hall

If you're in charge of purchasing office supplies, either for an employer or for your own business, then you know that one of the largest expenses in this category is inkjet printer cartridges. No matter what kind of industry you're in, there is no shortage of reports, invoices, announcements, and other paperwork that needs to be printed out and distributed on a daily basis. As a result, you're constantly replacing the ink in one or more printers around the office, and the supply cabinet is always running low on spares. And of course that sends your monthly expenses through the roof, especially if you purchase your supplies from traditional stores. If you want to start saving money on your printing costs, you should consider ordering inkjet printer cartridges from an online retailer instead.

Online retailers typically offer you savings on inkjet printer cartridges in two different ways. First, you can save money on the same name-brand OEM products that you would be able to buy at any traditional office supply store. Online retailers have the advantage of not having to maintain a physical storefront, so their total operating costs are significantly less than traditional stores. Most of these retailers are happy to pass the savings on to their customers, knowing full well that they'll make up the difference through higher sales volumes.

A second way that you can reduce your printing supply costs is by ordering remanufactured inkjet printer cartridges. As the name would imply, these are recycled inkjet printer cartridges that do not have a brand name attached to them. Instead, the used products are thoroughly cleaned, inspected, and electronically tested to ensure that everything is in working order. Then, they are refilled with quality ink and sold to customers with compatible printers. The remanufacturing process has come a long way in recent years, and users report that these inkjet printer cartridges work just as well if not better than OEM products. And, according to an article that appeared on the USA Today website, remanufactured inkjet printer cartridges are often sold for up to 85 percent less than their OEM counterparts. So if you print lots of documents every day, you simply can't afford to pass over this option.

Office supplies such as inkjet printer cartridges will always be a necessary expense for any business, but that doesn't mean you have to resign yourself to paying high retail prices. The next time you need to purchase ink for your printers, order from an online merchant so that you can immediately enjoy huge savings.

Three Must Have Accessories For Notebook Computers

2009-02-24T20:00:00.001-08:00

Writen by Lynn Chan

An Optical Mouse

Notebooks are normally equipped with touch pads which can be awkward. There's no substitute for the mouse. Notebooks are predominantly used on a static, flat surface. With wireless broadband hotspots mushrooming all over the nation's transit locations, table tops have become as much mobile computing desktops as surfaces on which lattes sit. The touch pads on notebooks are also rather vulnerable to damage by static electricity, which is a common occurrence in aircraft cabins, carpeted airport lounges and offices and will become a big problem when you're on the road and lose the function of your primary pointing device.

A good optical mouse, be it wired or wireless must be able to track movement on varying tabletop surfaces. Optical mice traditionally had problems with glossy, transparent, or light-colored surfaces, but technology has advanced to a level that these problems are almost non-existent. Although wireless mice are the trend these days, stick to a wired optical mouse by virtue that it does not require additional power or equipment to operate; as in batteries or receivers for wireless ones. You don't need extra equipment in your already-overloaded and heavy notebook bag!

A Multi-Device Charger And Power Adapter Combo

Notebooks do come with their own AC-to-DC power adapters, but notebook owners typically carry a cell phone, PDA and digital camera in addition to the notebook. It's almost impossible to carry the charging devices of all these things. Do yourself a favor by getting a multi-device charging/power adapter. Some of them even have the capability to simultaneously charge and power an additional gadget or two, giving you an extra benefit of keeping your most-used gadgets well charged up for action.

Built-In Wireless (Wifi) Connectivity Or PC Card

Notebook owners are generally mobile information warriors. It is almost impossible to ignore the wireless revolution going around; WiFi and soon, WiMAX Hotspots abound wherever you go. Instant access to the Internet's unlimited resources and communicative offerings are just a little electronic card away.

If your notebook does not have built-in WiFi, get a PC card version which is often sold for less than $30 at computer stores. Plugging in a WiFi PC card means you can access the Web, read and send your emails, instant-message your colleagues,family,buddies, broadcast your vacation video/photos or company presentations, and retrieve company information on secure virtual private networks anywhere, anytime you are around a hotspot, in broadband speed.

How To Choose A Computer Mouse

2009-02-23T20:00:00.001-08:00

Computer Mice

Every computer user can hopefully identify their mouse and the importance it plays in the daily operation of their computer. Mice are nothing new and for the most part are nothing overly complex, but the average user may not be familiar with all of the options and technologies that may go into these little devices. This Tech Tip will take a look at some of the features of mice that people may take for granted, or may otherwise be unaware of.

Tracking Technologies

Mechanical mice - Mechanical mice were the first ones used on computers, and can still be found for sale, despite the advances of tracking technologies. These mice feature a hard ball on the underside that rolls as the mouse is moved, and rollers inside the mouse allow the physical motion to be translated to the pointer on the screen. Some "ball mice" are a bit more advanced and replace the internal rollers with optical sensors, but the same principle applies.

Mechanical mice require occasional maintenance to keep the ball and rollers free of lint and other debris, and with numerous moving parts there is always a potential for problems. The use of a mouse pad is recommended for these mice as they not only provide a clean surface to work on, but also provide the needed resistance for the ball to roll smoothly.

The precision of mechanical mice is not particularly good, and although they may be fine for typical desktop work, they were never quite up to the task of detailed graphics work or serious game playing.

Optical mice - Optical mice replace the whole ball/roller assembly of mechanical mice with a beam of a light and an optical sensor. The beam of light shines down on the surface below the mouse and the sensor uses the light to track the movement. The images included with the listing for this optical mouse (http://www.geeks.com/details.asp?invtid=HTM-39GWT&cat=MOU) provide a glimpse at the bottom of the mouse, where the light and sensor can be seen.

Optical mice have several advantages over mechanical mice. There are no moving parts to break or otherwise cause problems. The need for maintenance is greatly reduced as the bottoms have no openings or rollers to collect lint. Although mice generally aren't heavy, the elimination of the ball and roller mechanism allows an optical mouse to be much lighter than a comparable mechanical mouse. The precision of optical mice is also much greater than mechanical mice, and the resolution can go from the low hundreds to the high hundreds (as measured in dpi, dots per inch).

Another advantage is that the need for a mouse pad may be eliminated with an optical mouse, as they do best while tracking on any smooth, flat surface. A clean desktop is generally good enough, but those looking to take the precision of optical mice to the highest level may opt for a performance "mousing surface". There are several precision mousing surface manufacturers, such as XRay Pads (http://www.xraypad.com/) and FUNC Industries (http://www.func.net/), that design pads to appeal to game players and others who demand the best performance.

Laser mice - Laser technology is the latest and greatest in computer mice tracking, and takes the advantages of optical to a new level. Most of the attributes of a laser mouse have been described in the optical mouse section, except for one. Instead of a fairly wide beam of light, it uses an extremely narrow beam of laser light.

The Logitech MX1000 laser mouse may be the mouse for you if you are looking for extreme precision. According to Logitech, the laser technology used in the MX1000 provides up to "20x more sensitivity to surface detailor tracking powerthan optical."

Hard Wired Connection Technologies

Serial Serial mice are fairly difficult to come by these days, as are the ports they need in order to operate. This technology is quite old and slow, and the popularity and convenience of USB has all but eliminated the need for this interface on your typical PC. But, there were mice that sported the 9-pin connection needed to connect to a serial port, and many PS2 mice used to include an adaptor for Serial ports.

PS2 - PS2 mice were the standard for a long time, as all motherboards provided two PS2 ports for connecting a keyboard and a mouse. USB technology has become so widely used that the slower and less convenient PS2 ports are on the verge of extinction with the Serial port. That said, not many mice are still sold that only support a PS2 connection, but there are still some available.

USB Most mice can now connect via USB, and include an adaptor to be used on a PS2 port, as well. It seems that just about any mouse now uses USB to connect, whether it is a wired mouse, or any variety of wireless mice that we are about to look at.

Wireless Connection Technologies

Radio Frequency The most common type of wireless mouse uses radio frequencies to communicate motion to a receiver that is connected to the PC. This generic wireless mouse (http://www.geeks.com/details.asp?invtid=RF-M308-RC-USB&cat=MOU) operates on the 27MHz frequency and the mouse itself is powered by AAA batteries which are not included. As you move up the price scale of RF (Radio Frequency) wireless mice, the packages will generally include an integrated rechargeable battery, as does the Logitech MX1000 discussed previously. Other features of higher end RF wireless mice include extended range, greater precision, and a receiver that doubles as a battery charger.

Bluetooth The Tech Tip on Bluetooth discussed the basics of this wireless technology, and how it was a good fit for 'lower speed' devices, like a mouse. Logitech and IOGear are two manufacturers offering products for Bluetooth users, in addition to more traditional mice. The Bluetooth mice are also battery powered, and use the 2.4GHz radio frequency to communicate with an included receiver/charger or other Bluetooth adaptor.

RFID A truly unique approach to wireless mice has been developed by a company called A4Tech. The A4Tech ND-30 RFID wireless mouse must be used with the included mouse pad in order to function, but there are no batteries in the mouse, and no cords on the mouse to get in the way. It works by using electro magnetic induction between the pad (which is plugged into a USB port) and the wireless, non-powered mouse. You never have to worry about replacing / charging batteries, and the weight of the mouse is greatly reduced since the power features are no longer necessary.

Features

Buttons Most mice (except for a Macintoch's) include at least two buttons. The use of these is fairly well understood, but other buttons may be featured on a mouse to further simplify common tasks. The Logitech MX 510 mouse features a total of 8 buttons which can be programmed to execute functions of the user's choosing.

Scroll wheels Many mice now include a scroll wheel between the two main buttons which serves to allow up/down scrolling of documents and web pages. The scroll wheel may also serves as a third button on some mice, and clicking the scroll wheel will activate commands in many applications. More advanced scroll wheels are found on some mice that allow for left to right scrolling, which may be useful on a wide spreadsheet or large image.

Extra features Many mice provide more than the basic functionality we have come to expect. Some provide a reduced foot print in order to make them more portable for use with a notebook computer. Some are designed for multi-tasking and provide an integrated flash memory card reader. Then, there are others that just look cool with a bit of a light show, or that actually keep you cool by including a small fan in the palm rest area.

Final Words

On the surface, computer mice are fairly simple devices that may not receive the attention they deserve by end users. Selecting a high quality, ergonomically designed mouse can do wonders for productivity and comfort, and the options available should allow anyone to find the right mouse for their personal preferences.

Learn How To Diagnose Power Supply Problems

2009-02-22T20:00:00.001-08:00

Writen by Otis F Cooper

The Power Supply convert's your regular household current into low DC voltage used by the computer. When this component fails,there is simply no activity going on wih your computer.Remember to do the easy troubleshooting first.Inspect the Power Supply for any damage.Double-Check all connections.

Learning how to check your power supply and how to replace it when needed can be a life saver if you're a computer buff or in business with the trusted PC.Don't take for granted the simple pleasure of turning on your PC and everything works just fine.

We turned on one of our computers recently and in about one hour,it just re-booted itself.And it continued doing so about 10 times a day until we found out the power supply was the culprit.Things to look for when your power supply is going bad or just dies on you are the following.

NO POWER TO THE COMPUTER

Here you must first check the wall outlet for power by connecting another device such as a radio or lamp to be sure power is present.If the computer is connected through a surge protector,check it as well.

If the wall out has power,check the power cable going to the PC to see if AC voltage is making its way to the system unit.Do this with the use of a multimeter.

If there is power,you will have to open the PC and check for power from the power supply to the motherboard.

When using a multimeter to check voltage,be sure you have a good ground for the black lead of the multimeter.

RE-BOOTING PROBLEMS

One main problem you may face with an ailing Power Supply is that it may re-boot the computer without any warning.All information is lost and it seems as though this happens at the worst possible time.

Booting errors when the computer first start's up is another indicator of this component going on the blink.

POWER DISTRIBUTION PROBLEMS

When the power supply begins to fail,you may receive power at one device and not another.For example,the Hard Drive may receive power but the CDROM Drive has nothing at all.

Another headache with would cause re-booting is the intermittent power going to the drives or the motherboard itself.Follow the steps below to check your power supply should you experience some of the above problems.

CHECKING THE POWER SUPPLY

If the wall outlet,and the power cord are good,make sure the connection at the motherboard is secure.Then you may have to face the fact that the power supply itself is bad.If you have a Multimeter you can test the power supply output before purchasing a new one.Simply follow these steps.

Turn off the PC,but do not unplug it,open the system unit. Set the multimeter to read DC volts in the next range higher than 12 volts.Locate a power connector similair to the hard drive,or cdrom drive connector that is unused and turn on the PC.

You can also unplug a drive connector and use it as well.Turn on the PC and insert the BLACK probe into the power connector on one of the BLACK wires.Touch the RED probe to the YELLOW wire on the power connector.

The multimeter reading should be +12 volts Now touch the RED probe to the RED wire and the reading should be +5 volts.If no readings or different readings occured,you'll have to replace the power supply.If the readings were correct,you should check the P8 or P9 connectors at the motherboard. These connectors may also be named P4 and P5.To check these connectors,perform the following...

Insert the BLACK probe into P8 at one of the BLACK wires. Insert the RED probe into the P8 connector at the RED wire. The reading on the multimeter should be +5 volts

Check the power going to the Motherboard connections by inserting the RED probe into P8 at the YELLOW wire and you should get +12 volts.Leave the BLACK wire touching the black wire at the P8 connector.Check the BLUE wire and the reading should be a -12 volts.

Now move the BLACK probe to the BLACK wire on the P9 connector.Test the WHITE wire by inserting the RED probe and the reading should be -5 volts.Check the RED wires on the P9 connector and you should get +5 volts on each red wire.You won't get exactly 5 or 12 volts but the readings will be very close, such as 5.02 volts.

If the Power Supply is a couple of volts off,in either direction,such as when the RED wire should be reading -5 volts but it reads -8 volts,or if there are no readings,replace the power supply.

DO NOT remove the power supply from the system unit case when performing these tests.DO NOT perform these tests if you do not feel comfortable.Be sure to remove any and all electrical static build-up from your clothes and body BEFORE touching any parts inside the system unit.And NEVER open the power supply case for any reason,since high voltage may be present.

Suppose you feel a burning desire one day to start building your own commercial product and become an employer yourself. Sooner or later you will experience this, and I want to help you finding the "means" you need to implement your dreams into reality.

In terms of hardware I suggest exploring dsPIC microcontrollers running at 120 MHz. They are the top products built by Microchip to date, and you cannot fail with those ones--trust me. Particular to Microchip products, they are the easiest to work with, and this is encouraging news to beginners. Do not be afraid of working with electronics. Today, almost all parts we use are modules, and all you have to do is put them together in the right way, almost like in a Lego game. Of course, in time, and with a lot of dedication, you could become an expert!

For firmware you do not need to shop around too much, because you are going to find the right tool you need again at Microchip: the C30 ANSI C compiler. This is an excellent tool and it has a range of 22 dsPIC microcontrollers to date, but few tens new ones, more powerful, are going to be added in 2006 and 2007. The good news is you can try C30 before you buy it, and you have exactly 60 free working C30 days. This is a lot of good working time, and you need to use it at maximum. It is possible you are afraid of this firmware "thing". Don't be. It can be as simple as sketching a story on paper, only a bit funnier, when you use C to write firmware.

Well, it is the dsPIC processors we are talking about, particularly dsPIC30F4011, and you think, probably, it is very difficult to work with this one. Not so, my friend. In fact, this is the easiest option available in the entire World today. Learning hardware, firmware, and software design can be incredibly easy, beyond your wildest expectations, with the right tutorial book. You are going to discover that exceptional book I refer to in my home site. Have no fears my friend: the book is very easy to read, just like this article I present here.

The true beauty is, the book comes with a Hardware Companion Kit (HCK). Fact is, this is a Practical Design Project and all firmware and software programs developed are thoroughly explained, and working. Of course, the companion kit is recommended for beginners in hardware, firmware, and software design. For advanced levels designers it is not mandatory to purchase the companion kit. Here is another interesting aspect: the level of the book is beginners, medium, and even advanced designers. The amount of useful, practical, working examples it presents it is tremendous!

You do not need to be an expert to learn working with dsPIC microcontrollers. On the contrary, you could become a GURU in 60 days! All it takes is determination and little desire to learn. This is all! If you have what it takes than do it, my friend. Once you know the "how-to" you take charge: discover you commercial product and build it. We live in a free market World and everybody is welcome!

My advice is, look at the simplest things around you: a door, a window, a lamp, a bicycle, and so on. Think about adding useful intelligence to any of them. Our life is driven by hardware, firmware, and software today, but there are still thousands and thousands of unexplored avenues. If you keep on looking for them, you will discover your commercial product one day--I have no doubts about this.

Take for instance something very blunt, even vulgar: a hammer. You can easily design a tiny hardware module to count how many times it struck per day during the past year, and how hard was each blow. Next, you can design your intelligent hammer to "talk" to your PC and download the data it contains. This is not all, because once the hammer data is on PC it will be processed graphically, for statistical analysis, or for even more advanced analysis. Your "intelligent" hammer may even access a site on the Internet by itself and exchange data there. Mind this please: I describe here the blunt "Hammer Application"! For smarter ideas things may look way more interesting, and the book I mentioned teaches you everything you need to know to design intelligent control applications. Even more, you will discover in my home site few pages dedicated to basic electronics, and to many other exciting topics.

Anyway, it will take some time until you discover your beneficial commercial product. Meanwhile, you can enhance your resume and your technical aptitudes. The more you learn, the better prepared you will be when the right time comes.

Uninterruptible Power Supplies

2009-02-20T20:00:00.001-08:00

Writen by Steve Valentino

The loss of electricity supply is technically called as power outage. It is specifically referred to as "brownout" when some power is lost but retained some voltage level, albeit not enough for the minimum level required by a certain system. On the other hand, it is called "blackout" when the power is completely lost.

When power failures occur, your appliances or any other electronic devices are the things that suffer most from the damaging. Your computer unit is featured with a power supply, a device that is used in generating electricity to keep it operational. The switcher technology of this device will convert the alternating current line into direct current input. This enables the computer to start functioning. However, once a power outage occurs it will stop producing power. As a result, the computer will end its operation. As mentioned, this occurrence is detrimental to your computer. If this incident continues to occur, it will suffer serious damage and require extensive repairs that could run into a lot of money.

Fortunately though, there is a device that counters the situation in the form of Uninterruptible Power Supply or UPS. A UPS is a device used to protect computers and electronic equipment from the damaging effects of power outage incidents. It is a battery-driven power supply that is active even whenever sudden loss of power has occurred. There are certain types of uninterruptible power supplies with variety of capacities. There is a small unit type that can service a single computer in a home or office. There is also the kind that can provide protection to a business environment that runs with a big computer network.

Uninterruptible power supplies are necessary tools both in large business establishments with a wide network of computers and in a home/office with individual computers.

Large Format Scanners

2009-02-19T20:00:00.001-08:00

Writen by Damian Sofsian

It is generally accepted that the future of both storage and printing is digital. In case of text, it means scanning followed by conversion using optical character recognition. The development of large format scanners was impelled by the need for converting large drawings and images into digital format, as required in digital archiving, image acquisition, and customized reproduction. Other applications were realized in the areas of digital conversion of manuscripts, traditional art and fabric designs. Typical image widths range from thirty-six inches to forty-two inches, though widths of up to sixty-two inches are commercially available. Such scanners usually use several small format sensors to increase the format width and are available in color as well as black and white. The former are more expensive and are used only for more demanding tasks than ordinary data entry.

Charge-coupled device (CCD) has been traditionally used to capture the image. The earlier method of three-pass scanning, which used a different color filter for each pass, is being replaced by the single-pass method. A relatively new imaging technology using contact image sensors (CIS) is becoming popular for low-cost applications requiring less power and no warm-up. Though CCD scanners have a wider color gamut and a larger dynamic range, CIS scanners have better resolving power and higher geometric accuracy. This makes scanners using CIS ideal for digitalizing technical documents. These scanners are also more compact and easy to carry. However, owing to its better chromatic accuracy and better depth of field, CCD technology retains better image quality near an open spine and is thus suitable for scanning books, portraits, and paintings.

The choice of a large format scanner naturally depends on the application in mind, which dictates the type of the scanner, imaging technology, permissible thickness of the medium, resolution, width of format, speed, etc. Some of the leading manufacturers of large format scanners are Colortrac, Oce, Contex, Altek Corporation, ACTion Imaging solutions, ANAtech, CST, Vidar systems, and WideCom.

Laser Printers Or Inkjet Printers A Buyers Guide

2009-02-18T20:00:00.001-08:00

Writen by David Haysom

Should you buy an inkjet or a laser printer? Often people buying a new printer are confused about whether to buy a laser printer or inkjet printer. The short answer is it depends on what you'll be using it for, and how much you'll be using it.

Inkjet printers have a lower initial purchase cost but cost more to run because the ink is more expensive when measured on a per page basis. Laser printers cost more but their running costs are lower and they have a better print quality because in general they have a higher resolution (expressed in dots per inch - dpi).

If you want to print photos at home however, you are best to choose a photo quality inkjet printer.

Inkjets are great for home use and for photo printing. Lasers are good for high-volume applications, like offices, or for applications that need high print quality.

Inkjet printers transfer tiny droplets of ink directly to the page. A laser printer creates an electrostatic pattern on a drum that attracts ink powder that is subsequently fused onto the paper. This is more complex technology so means a higher price than for an inkjet printer.

If you examine the same page printed on both a laser printer and an inkjet, you will be able to see that the characters on the laser printer produced page are sharper. That said however, inkjet printers are getting better all the time in terms of the sharpness of printed characters.

Another aspect to consider is how heavily you will be using a printer. Printer manufacturers express the durability of a printer in terms of duty cycle in pages per month.

For example, a typical laser printer will be capable of a duty cycle up to 7,000 pages a month while a typical entry level inkjet printer is capable of up to 500 pages per month.

Some of the more recent inkjets provide excellent color clarity and brightness, and are very well suited for printing photographs.

While inkjet printers themselves are cheaper, their ink is more expensive per page printed. Ink cartridges need to be replaced fairly often if you print a lot, especially if you're printing pictures or photos.

The manufacturer's stated pages per cartridge measurements are very much dependent on what you printing. They are based on only a small percentage of the page actually being covered in ink.

Toner cartridges for laser printers have a higher unit price than inkjet cartridges, but have a higher capacity so that the cost per page is lower for lasers.

A Look Inside The Elusive Inkjet Industry

2009-02-17T20:00:00.001-08:00

Writen by Niall Roche

The Inkjet printer industry is booming. Office supply companies report they make more money on ink sales alone than on printer sales overall. Due to increasing ink sales, many inkjet manufacturers have introduced innovative products and services to meet the demands of discerning consumers. Customers are now able to purchase refill kits that allow them to handle their inkjet needs at home, without having to purchase expensive new cartridges. Refill kits contain a syringe like instrument that injects ink into the cartridge.

In addition to ink refill kits, some printer manufacturing companies are also designing a chip that can detect when the cartridge is nearing the depletion level. On some models, this service will even report the number of pages left to print. Manufacturers believe this type of service will be beneficial to customers because it will enable them to know they are about to run out of ink, before it actually happens.

Despite the measurers that manufacturers have taken to lighten the financial burden on consumers who purchase ink products, consumers frequently try different strategies to conserve their ink. One of these strategiesis to produce bulk quantities in black ink, under the mistaken impression that this will conserve their more expensive color ink cartridges. Unfortunately, this strategy doesn't work because color ink is required to make black ink on some machines.

One strategy that will work is to realize that it takes significantly less ink to print a standard page of text than it does to print a color photo. In fact, a color photo requires 30 times more ink than a single page of text. So, use your ink wisely.Another way consumers can save money is in the quality of the printer they purchase.

Consumers frequently purchase printers based on the sales price, failing to realize that by the time they purchase printing supplies, like ink cartridges, it is cheaper in the long run to go with more expensive inkjet printer that has cheaper consumables. The initial cost difference can easily be made up by the difference in the cost of consumables.

In recent years, the inkjet industry has developed printers capable of printing faster than ever before. Some printers are now capable of printing out 20 pages per minute. Before consumers rush to purchase a printer with such lightning fast capabilities they need to give some consideration to the type of projects they will be printing. Some printers are perfectly capable of printing several pages per minute and maintaining print quality at the same time; however some are not. Take the time to shop around in the inkjet aisle to find the printer that will serve your personal daily printing needs.

With all these new changes in the Inkjet industry, it's important for consumers to take the time to research the many new services and products now on the market. This is the key to understanding the constantly evolving inkjet printer industry.

Benefits Of Compatible Printer Inks

2009-02-16T20:00:00.001-08:00

Writen by Carla Weaffer

Personal computers along with inkjet printers can be found in many homes these days both for personal and home office use. As prices for inkjet cartridges can become quite expensive, it can be a wise consumer decision to look into purchasing compatible printer ink cartridges.

What are compatible printer ink cartridges? Compatible printer ink cartridges are refurbished printer ink cartridges that are compatible with Epson and Canon printers just for example. Purchasing compatible printer ink cartridges can be beneficial in several ways. There are very few consumer printer models that are not compatible with compatible printer ink cartridges.

The first reason that it is a wise consumer decision to purchase compatible printer inks is that it will save you money. Replacement cartridges that are produced by printer manufacturers can a lot of the time end up to be more expensive then the printer itself. If you were to do some comparison shopping you will see that compatible printer ink cartridges will end up costing less than cartridges produced by manufacturers. Consumers that buy inkjet refill kits can greatly extend the life of a printer ink cartridge, thus saving them money.

Ease of purchase is another excellent benefit to purchasing and using both compatible printer ink cartridges as well as inkjet refill kits. It is extremely easy for consumers to locate a retailer of compatible printer ink cartridges online at more reasonable prices then brick and mortar stores. Most consumers appreciate the convenience of this as they do not even have to leave their home to order a new printer ink cartridge.

If you use an inkjet refill kit you will be helping to reduce the amount of solid waste getting disposed of into landfills. In addition to that the use of inkjet cartridge refill kits are very convenient as you can often refill a cartridge several times with one refill kit. Using a compatible printer ink cartridge along with an ink refill kit can greatly increase the life on an ink cartridge as long as the cartridge is refilled before reaching the empty point. Also as most ink contained in quality compatible ink cartridges and ink cartridge refill kits is very good quality it would be possible to purchase a number of cartridges and store them for later use. Since the printer ink is of a quality you should not have to worry about stored printer ink producing a poor quality print job.

Many consumers are under the impression that using a compatible printer ink cartridge or an inkjet refill kit will void the warranty on their computer. This is not the case, as typically the use of compatible printer ink cartridges will not void the warranty on a consumer printer. Another concern of individuals looking to purchase a new printer is that it will produce a print job that is inferior to a ink cartridge. A quality compatible printer inkjet cartridge will produce a print job equal to that of a cartridge produced from a manufacturer, sometimes even better in some cases.

So when you are looking into purchasing a new printer, remember all the great benefits that go along with using compatible printer inks.

Writen by Jason Gluckman

Your PC is incomplete without a monitor. A computer monitor is required for all desktop PCs, to see the characters and images processed by the computer using the graphic card.

Computer monitors are designed according to the display standards laid down by the industry. Occasionally these are called heads, when referring to several monitors used to display data using only one computer. Generally, the cathode ray tubes used for display screens are rectangular in shape, but circular and square screens are also popular

Present-day computers use a cathode-ray tube to display characters. This tube is made of glass and connected to a flat screen on one end, tapering to a narrow end on the other. A single electron gun is connected to the narrow end of the tube for a single-color monitor whereas three electron guns are required for multicolor monitors. The monitor emits light when the electrons strike the screen.

Although computers have become an integral part of our lives, using these machines for a long period of time can cause visual problems and headaches. The glare on the computer screen can strain the user's eyesight, especially when trying to read small characters on the monitor.

Call an expert immediately if your screen is flickering noticeably, and adjust the contrast balance between the text and the background. Eye specialists advise you take regular breaks from your work, and try focusing your tired eyes at an object twenty feet away from your work station.

Keep your computer monitor clean using a mild cleaner, and wipe it using a lint-free cloth. Close your eyes whenever you are tired, and don't hesitate to use eye drops to soothe your dry eyes.

Playstation 3 Vs Nintendo Wii

2009-02-14T20:00:00.001-08:00

Writen by Victor Vargo

There will always, regardless of our time in space in the span of human history, be an open competition between those who believe in the old school and those who side with the new school. In other words, those that believe that there needs to be some traditional guidelines for how to be a success and those who believe you have to change all of the rules. While Nintendo has certainly been at the forefront of the gaming industry since its inception, few would argue that they have, "kept up with the Joneses" so to speak.

Nintendo is trying to change this fact with the introduction of their latest competitor in the video game industry, Nintendo Wii. However, those who are "new school" in the video gaming world will tell you that Sony has far surpassed Nintendo in the gaming industry to a point that the talk of a "competition" is almost comical. Regardless of where you stand on this argument it is always a good idea to know what everybody has to offer and in that spirit here is a small comparison of PlayStation 3 and Nintendo Wii.

PlayStation 3 has introduced perhaps the most powerful processor in the history of gaming with their Cell Broadband Engine that will allow for awesome game play to jump start this edition of the PlayStation Empire. Nintendo Wii has a very good "PowerPC" that they have nicknamed "Broadway" that will allow for a good gaming experience. Nintendo stepped out and solicited the help of IBM for the production of the Wii processor, meaning that they are seriously looking to re-enter the video game wars.
One feature of both the Nintendo Wii and the PlayStation 3 that will both impress and excite gamers is the fact that both are backwards compatible, meaning that you don't have to throw away your favorite games from the previous console. PlayStation 3 owners will be able to play games from both the previous PlayStation consoles, while Nintendo Wii owners will be able to play Nintendo Game Cube games whenever they want.
Both consoles are "always on" which means that any communication needed to get updates or make changes to your system will happen without you worrying about being logged on or retrieving important codes. Both use wireless router technology and are able to connect whether you are at home or even logged on.
Perhaps the most exciting aspect of each console is the advent of new controller technology in both the PlayStation 3 and the Nintendo Wii. The Wii will introduce a long and skinny remote that has motion sensors to pick up your movements and use them within the game. PlayStation 3 will be introducing the same type of technology to allow a more real and sophisticated experience for every user.

What Is A Fuse And How To Test It

2009-02-13T20:00:00.001-08:00

Writen by Jestine Yong

A fuse is a very thin wire, which either melts or vaporizes when too much current flows through it. The thin wire may be made of aluminum, tin-coated copper or nickel. The resulting open in the circuit stops current flow. In electronic equipment, most fuses are cylindrical glass or ceramic type with a metal cap at each end! The current rating also can be seen in one of the two metal end caps. There are two popular physical sizes: 1 ¼ X ¼ - inch and 5X20mm. The 1 ¼ X ¼ - inch size is used in many automobiles. You'll find both sizes in many electronic equipment, but the smaller 5 X 20mm has become more common. Fuses are available with current ratings from 1/500 Ampere to hundreds of amperes.

Purpose of Fuses

The purpose of a fuse is to open an electronic circuit when current flow exceeds a certain amount, determined by the rating of the fuse. Opening a circuit under high current conditions can save electronic components from damaged and prevents overheating, which could cause a fire.

Types of Fuses

There is two basic types of fuses: fast acting and slow blow. The fast acting type will open very quickly when their particular current rating is exceeded. This is important for analog meter movements, which can quickly be destroyed when too much current flows through them, for even a very small amount of time. Slow blow fuse have a coiled construction inside. They are designed to open only on a continued overload, such as a short circuit. The purpose of coiled construction is to prevent the fuse from blowing on just a temporary current surge.

Do not use a slow blow fuse in place of a fast acting fuse. It may not open fast enough to prevent components damage under a high current condition. It's not harmful to replace a slow blow fuse with a fast-acting fuse, but it will probably open up unnecessarily every now and then when the equipment is first switch on. A blown fuse can tell you something about your service problem. Often the glass case of the fuse appears clear, and you can still see the broken pieces of the fuse element. This means you have the kind of problem that causes a slow, gradual overload on the power supply. Some fuses even die of old age. But if the inside of the glass fuse is discolored, and there is no trace of the fuse element (the center connector), you know that the center connector was destroyed quickly and violently, using a lot of heat. The fault was a short circuit or other problem that caused a lot of current to flow very quickly.

Is some cases a fuse will open up fast enough when there is a surge so that other components aren't damaged. If this is the case, replacing the fuse with one of the same type and rating restores operation. Unfortunately, a high probability exists that if a fuse blew, something in the circuit it was protecting shorted out. In this case, a replacement fuse blows right away. The blown fuse can easily be replaced by a new one, after the overload has been eliminated when come into replacement. Use only the same current and voltage ratings as the original. The common type and current rating of a fuse in a monitor are slow blow 2A to 5A. When you buy replacement fuses, get several you can easily use all of them while you're troubleshooting an elusive problem.

Testing Fuses

Turn the power off and remove the fuse from the circuit to check with a multimeter set to the lowest ohms range. Connect the probes to both end of the fuse. You may check the fuse while it still in circuit. A good fuse should showed continuity or read 0 ohm. A blown fuse is open which reads infinity on the meter.

Have you ever wanted you ever wanted your own troubleshooting guide for your toner cartridges?

Well here you go!

Your Toner Cartridge Troubleshooting Guide:

Below are some common problems that may show up during your printer usage. Here's what will happen and how to fix them:

Dirty PCR (primary charge roller): A dirty PCR, which is located inside the printer, will cause vertical gray streaks down the test page or create a gray background on the entire page.

Scratched Drum: This condition is indicated by a very thin, perfectly straight line that runs from the top to the bottom of the test page.

Chipped Drum: A chipped drum will make a dot or series of dots that repeat three times per page. Any drum defects will repeat three times per page based on the drum circumference of 5.2".

Light Damaged Drum: This condition will show up as a shaded area on the test print that normally should be white. Again, this will repeat three times per page.

Bad Wiper Blade: A bad wiper blade will make either a gray line approximately 1/8" thick or shading across the entire page. In either case, there will be a film of toner on the drum surface.

Weak Doctor Blade Spring: This will usually show as shaded areas on one or both sides of the page.

Machine Error Codes:

32 Unsupported Print Cartridges: (Wrong chip, encoder wheel combination or bad chip). If this code appears immediately upon cartridge installation, there is either a bad contact or the chip is bad. If the machine cycles and then the message appears, the wrong encoder wheel is installed. In the T632 machines, this message will also show if the extra high yield cartridge is not installed.

80 Scheduled Maintenance: The code appears when 300,000 pages have been printed.

88 Toner Low: Add toner.

Capitol Flag Displays

2009-02-11T20:00:00.001-08:00

Writen by Jimmy Sturo

The Capitol Flag Program began in 1937, when a member of Congress asked that a flag be flown over the Capitol. The program now includes flags that are flown on national holidays and special events. Flags that are used to honor the work done by schools and civic organizations are also included in the Capitol flag program. Since these flags are always used to commemorate special events, they are considered to be unique and rare items.

A number of online companies and local shops offer Capitol flag displays. These displays are available in acrylic or glass with wood or metal bases. The transparent cases are semi-circular, pyramid and flat laid out shapes that allow a viewer to have an unobstructed view of the inlaid flag. The size of the flag determines the size of the display. A number of these artifacts are passed on as heirlooms. For this reason, the materials used to build the cases are sturdy and durable. A number of Capitol flag displays used in museums are specially tinted for added protection.

In recent times, the demand for Capitol flags has rapidly increased in comparison to supply, because many congressmen and senators order them to emphasize their state. The purchase price of Capitol flags includes flag costs, postage and handling charges and supplementary charges for set up. These high quality flags generally last for many years and come with a certificate of authenticity. The certificates provide a date and place detailing when and where flag was flown over the Capitol. In most cases, along with arranging Capitol flag displays, enthusiasts and collectors purchase a certificate case to go along with the flag.

Buying A Refurbished Pc

2009-02-10T20:00:00.001-08:00

Writen by Dave Stewart

Refurbished desktop computers are essentially second hand pc's. Refurbished desktop computers come from two main sources, returns and trade-ins. These days the majority of manufacturers recycle their returned stock, whether they were considered faulty by the consumer or returned for other reasons. You may have also noticed other consumer electronics popping up on the market described as 'manufacturer refurbished', these products come from the same process as refurbished computers.

Simplistically when a manufacturer refurbishes a computer they;

Clean the machine and peripherals

Test each component individually to verify that they still function properly

Format every hard drive, to remove any data stored on them

Assemble the parts to form a 'new' refurbished system

Test the system again, as a complete platform

Install an operating system and hardware drivers

These systems are then put back on the market as refurbished systems, with a lower price tag reflecting this. So now you're wondering, should you buy a refurbished desktop computer? There isn't really a simple answer, it all depends on the individual system and your circumstances. By circumstances I’m referring to your budget and what you're going to use the system for. For information on determining what you need in a computer from what you're going to use it for check out http://www.discountdesktopreviews.com/articles/finding-a-cheap-pc.html . Once you have decided whether a refurbished system would suffice your needs, you then need to look at your budget.

For those running a tight budget, refurbished systems are a great way to save some cash when buying a new system. If, on the other hand you have more money to spend on a pc, you should consider the limitations and disadvantages of a refurbished pc.

A big limitation of refurbished computers, and all refurbished consumer electronics for that matter, is the inability to customize your purchase. When you buy a brand new computer, you have the choice to customize it to your needs. With refurbished systems they come as they are.

Another disadvantage of second hand systems is the fact that what you can buy, is constrained by what consumers have returned. If you're looking for a specific part or setup then you may have great difficulty in finding it in a refurbished pc.

Finally when purchasing a refurbished computer, you need to check whether it comes with a warranty and the specifics of the service or repairs.

A Review Of Brother Laser Toners

2009-02-09T20:00:00.001-08:00

Writen by Max Bellamy

Brother is right up there with HP and Samsung as one of the most sought-after brands of laser toner. The Japan-based Brother Industries was first famous for its sewing machines. It went on to produce all kinds of office equipment, such as machine tools, fax machines, label makers, printers, and other office equipment. They began making dot-matrix printers in the 1970s. In the 1980s, after HP blew up the market, Brother began releasing their own laser printers to consumers, and to other companies under the name of OEMed. Brother has a great reputation for printers and printing accessories.

You can buy new toner from Brother. There you will find plenty of personal, home, and small business laser toner cartridges and refills. You can also buy new toner refills in bulk, for middleweight to heavyweight business in need of massive amounts of toner on a daily basis.

One popular Brother laser toner cartridge costs about $34 from their website. This will yield about 2200 pages at 5% printing capacity. This percentage means that 5% of the page is assumed to be covered in ink. If you print a lot of photographs, that number will be much lower.

Be careful when buying Brother toner from third-party distributors. They will offer you lower prices under the umbrella terms of "compatible" or "remanufactured" laser toner cartridges. While some of these are perfectly reputable and suitable for a full range of printer uses, many others are below par. These phony cartridges will produce bad printing results and possibly damage your printer. Sometimes a third-party distributor might even package phony cartridges in real Brother packaging. You can find a list of authorized Brother retailers at their website.

Laser Toner Info provides detailed information about later toner cartridges and refills, as well as reviews of laser toner products. Laser Toner Info is the sister site of Brochure Printing Web.

Video Card Guide What You Should Know When Purchasing Video Cards

2009-02-07T20:00:00.001-08:00

Writen by Donny Duncan

When choosing a video card, it is important to know what you're going to be using it for.

The cheapest route is to find a Motherboard with one built into it. This is sufficient for most users. If you simply don't want one built into your Motherboard, or can't find one, pretty much any cheap video card will do for everyday use.

If you're into gaming, there are a lot of factors that make a video card "gaming" quality.

Memory - Video cards have memory (RAM) built onto the card that it uses for its calculations. This is the primary selling gimmick when it comes to most video cards, but simply having a ton of memory on the card won't make it fast, it also depends on what kind of memory it is, DDR currently being the best. Another factor in memory is how many bits it runs at, the higher the better.

Interface - The interface is the technology used on the card to connect it to the motherboard. The motherboard has to support the interface of the video card you're using, or it simply won't work. There are a lot of different types of interfaces now, from PCI, to AGP, PCI Express, and there are also different variations of AGP, like AGP 4x, AGP8x, etc. The AGP interfaces are usually backwards compatible, but they are not usually forward compatible, so you can put a 4x card into an 8x slot, but not vice versa. These are also never cross compatible, so you can not put a PCI Express card into a regular PCI slot, or into an AGP slot.

Interfaces also regulate how fast the card can be. PCI is the slowest, then AGP scaling up to the various versions of AGP, and the fastest currently being PCI Express, which is used on most of today's high end video cards.

Other factors that you might want to consider that don't necessarily have anything to do with speed:

Resolution - How large of a screen the video card can display on. If you have a very large screen, you'll want a card that can display in a larger resolution.

Outputs - The kinds of connectors that the video card has to connect to a monitor. VGA is the most common, but is also the lowest quality. A lot of monitors, especially LCD monitors, support DVI now, which is a higher quality output. Some also have S-Video outputs, or possibly one of each, or multiples, which brings us to whether or not it can support multiple displays.

Multiple Display Support - Regulates whether or not the card can display to multiple monitors at once. Some cards will have multiple connectors of a single types, others will have several different types, it just depends on the card. While most cards with multiples of the same type will most likely support multiple monitors, the ones with several different types won't necessarily support multiple monitors. Windows XP has built in support for stretching your screen across multiple monitors, so you just have to find a card that supports it.

Aluminum Laptop Cases

2009-02-06T20:00:00.001-08:00

Writen by Thomas Morva

A laptop is a very delicate instrument that has to be taken care of when traveling, and this is the reason people use laptop cases. One of the sturdier laptop cases is the aluminum laptop case. In fact, it is often considered a Fort Knox for your portable computer. Actually, a few years ago, owning an aluminum laptop case was quite difficult, as there were not many cases in production. However, nowadays the cost has shrunk drastically, while its availability has increased tenfold. So many people are opting for aluminum laptop cases.

An aluminum case is of course made of aluminum, sometimes with extruded aluminum frames. Most of the aluminum laptop cases come with grey ABS plastic pads on their bottoms to keep them from scratching desks. The handle of an aluminum laptop case is sturdy, with a comfortable molded plastic grip and a removable shoulder strap. For the safety of the laptop, the aluminum laptop cases usually have one or two combination locks. The inside of an aluminum laptop case has a lining with mesh and vinyl leather-look trim, some padded divider panels to separate the laptop from accessories, and also lots of pockets to hold necessary cables and discs. To keep the laptop fitted snugly into the aluminum laptop case, the bottom of the case has totally customizable Velcro-adjustable dividers.

The advantage of using an aluminum laptop case is that it gets reduced shipping costs in the event of shipping of the laptop. It is easy to handle in all weather, as it is both water- and dust-resistant. There is little risk of the laptop getting damaged if the aluminum laptop case falls. Aluminum laptop cases are recyclable, and are thus beneficial to the environment.

How To Use A Usb Flash Drive

2009-02-05T20:00:00.001-08:00

Writen by Damian Sofsian

The popularity of USB flash drives does not solely come from its convenient size and the amount of data it can store but also in its easy use. It is very simple to operate and use a USB flash drive provided that the computer you connect it to has all the installed drivers that support the device. However, if the computer does not have an existing driver, USB flash drive installer software is also very easy to install and operate.

The protruded "connector" of the USB flash drives is simply plug directly into the computer or to a plug which is directed to the USB port. The computer then detects the device and upon detection, a folder containing all the files in your USB flash drive would appear on the computer screen. Files can then be easily accessed and transferred to the USB flash drive simply by dragging these files or by copying them into the USB flash drive folder. After using the device, the user can simply detach the flash drive from the port and use it again similarly with other computers.

USB flash drives can be used with most computers as long as they have a USB port and the software compatible with the drive to make it run. A lot of the newer operating systems have pre-installed USB drive drivers, but for those with operating systems that are quite dated, USB flash drive makers also offer drivers which may be used with these systems. These are easy to install and to use, as well. The compatibility of the USB flash drives and the availability of drivers in order for it to run must be checked with the manufacturer before even purchasing your flash drive. However, almost all USB flash drives work well with most computers.

Using USB flash drives are even simpler and more accessible than CD-R or DVD-R, besides USB ports are more common than CD or DVD equipped computers. Also, files stored in the USB flash drives may be erased as often as the user wants it to and may be changed as well.

The novelty of USB flash drives have long gone, yet despite this, users still enjoy its power and portability.

Wireless Usb Vs Bluetooth

2009-02-04T20:00:00.001-08:00

Writen by Preston Wily

USB is currently the industry standard If you spend any amount of time on a computer chances are that you have used a USB device, such as a mouse or a keyboard. There are currently more than 2 billion USB devices in use around the world.

Cables can be a mess When USB first became popular (around the year 2000) everybody loved the technology and embraced it. It was so easy to use and offered inter-compatibility with virtually every PC. As we became increasingly more reliant on USB for most of the devices that connected to our system the nest of cables behind the average computer continued to grow.

Enter Bluetooth Bluetooth was released a couple of years following the initial release of USB and grew in popularity because it offered computer users a way to connect precious devices to the computer without worrying about the tangle of wires behind the computer and the inevitable "creative" wiring options required to connect two computers and printers located across the room.

Bluetooth took off in Europe and Asia Bluetooth has become very popular in Europe and Asia. Not only is Bluetooth popular with computer users, but also cell phone users looking for a way to use a hands-free headset without worrying about hauling around another wire. For some reason the technology became very popular abroad, but many US computer and cell phone users had security concerns about the technology or were unimpressed with its relatively low speed for data-intensive applications.

We are on the verge of a revolution in connectivity Wireless USB offers the convenience of Bluetooth with the security and seamless integration of current USB technology. In addition, the first release of Wireless USB (aka WUSB) will allow you to use legacy USB devices wirelessly. Here's how it will work - you will plug a Wireless USB dongle into your desktop or laptop and then plug the Wireless USB hub into an external power supply - this could range from a few feet to several meters away. Then you could plug your USB devices into the Wireless USB hub and use them as if they were attached directly to your computer. This would be especially useful for a printer, scanner or any other device you might want to share with local computers but not necessarily over a network.

Differences between Bluetooth and Wireless USB The most obvious difference between Bluetooth and Wireless USB is the speed - empirically you will generally always see speeds less than 1 Mbps with Bluetooth. Wireless USB, on the other hand, is rated for 480 Mbps at 5 meters. Both technologies are slower at further distances, but Wireless USB should always be faster than Bluetooth. Another obvious difference between Bluetooth and Wireless USB is security - Bluetooth devices are highly susceptible to signal-hijacking wheras the security standard for WUSB is very strict and should result in a much more secure connection - this is very important for any application which may require the transfer of sensitive data or information.

Time frame on Wireless USB Wireless USB dongles and hubs are currently in production and should be available for purchase in the first quarter of 2006. A few manufacturers have already received approval from the FCC and other stanards organizations.

Is Wireless USB right for you If you can hold off a couple of months to try out a really cool wireless technology I highly recommend that you consider WUSB. It may take some time to refine the protocols and iron out a few bugs in the design but the wait should be well worth it.

Preston Wily is a product development manager for Sewell Direct, an online retailer of hard-to-find USB adapters. Sewell Direct is currently establishing relationships with manufacturers of Wireless USB peripherals and devices and plans to offer these products as soon as they are available.

While it can be fun and useful to have some the smaller stuff, the truth is that there is plenty of high tech equipment, available at a reasonable price, that can help you get your professional business off the ground.

Professional grade listening devices are a must in any arsenal of professional spy stuff. These go beyond the pens outfitted with mics and get into some serious listening ability. Listening devices that can allow you to hear what is being said 300 yards away are ideal for many professional jobs. Simply hook your device into a high tech recorder and listen and record at the same time. It is even possible to use devices that cancel our background noise, allowing you to hear the object of your surveillance much clearer.

Another piece of spy stuff is some sort of night vision accessory. Many operations are done under cover of darkness, and it is important to be able to see without creating a light that could draw attention to your location. Night vision is not just about those goggles that you wear on your head; it is also possible to get binoculars and monocular that can aid you in seeing at night. The best devices do not rely on stars or the moon. This means that you can do surveillance in any kind of weather, no matter how cloudy or dark.

Nvidia Geforce 7800 Gtx Review

2009-01-31T20:00:00.001-08:00

Writen by Nicholas Spriggs

Nvidia has done it again, with it's newest video card, the geforce 7800 GTX. If money is no object and you demand the best, this is the video card for you.

The 7800 GTX, which promises 600 MHz, 256 MB of 256-bit DDR3 memory and a graphics core clock speed of 430 MHz, is the absolute fastest video card, to date, that money can buy.

Despite the high clock speeds, the 7800 utilizes a single-slot cooling solution. This is made possible because of the processor size which is 20 NM smaller then their previous 8600's. Also contributing to the cooling of the card is the improved power managment system, which automatically turns off unused portions of the chip.

The 7800GTX is equipped with 24 pixel shader units and 8 vertex shader units. With over 200 GFLOP's of shading avaliable, Nvidia raises the bar, once again, on video card's graphics and performance.

This is all in just one videocard, pair them up in SLI mode and you have the best video cards in terms of speed, stability and appearance. One thing to watch however, when running dual cards in SLI mode, is that unless you have a top of the line processor, such as the FX-55 you may find your video cards waiting on your processor to catch up. In this case you may want to hold off on getting both cards untill you upgrade your processor.

Inkjet Refills

2009-01-30T20:00:00.001-08:00

Writen by Richard Romando

Inkjet printers are the printers that dominate the consumer market. Although contrary to popular belief, inkjet printers are not successors of the dot matrix printers. Thermal printers are used for specialized printing in industries similar to those previously serviced by the dot matrix. You can purchase an inexpensive inkjet printer that gives you fast and high-quality printouts. You can even purchase ones that can print out photos with realistic-looking colors at reasonable prices.

A marketing strategy used by inkjet manufacturers: printers are sold at a very affordable price, but in order to maintain the quality of the printouts, you are required to purchase specific kinds of ink. These inks are usually very expensive.

There used to be no alternatives to such products. You were stuck buying these inks at high prices. Nowadays, you can purchase ink refills instead. Ink refills are not manufactured by the same companies that produced your printer or the ink that comes with it. They come at a very low price compared to the original inks. Inks refills usually come in remanufactured or recycled ink cartridges. You can purchase do-it-yourself refill kits or ink cartridges that have already been refilled. You can save up to 80 percent off the price of original inks if you opt to use ink refills.

The problem is that once manufacturers discover that you have used alternative ink over the original one that is recommended for your printer, the warranty of your equipment is automatically void.

In using ink refills, there is also a very high chance of ink bleeding, which can ruin the printer heads of your printer, making it defective. Even without this happening, manufacturers may still be able to detect if ink refills have been used on your equipment. Newer printers are now equipped with features that can detect the authenticity of the ink that you use.

Some consumer are willing to take the risk of using ink refills because of the substantial savings they can get from such products.

Will Ipods Change The Way We Watch Television

2009-01-29T20:00:00.001-08:00

Writen by Ro Russell

The industry was intrigued by Wednesday's announcement that episodes of the hit ABC shows "Desperate Housewives" and "Lost" will be available for Apple's new video iPod. Episodes will go on sale for $1.99 on iTunes the day after they are broadcast.

For ABC and its parent Walt Disney Co., the bet is that the new technology will bring in more new fans of the programs than will be taken away from watching them on traditional broadcast television.

The network's affiliates were not told the deal was in the works before Wednesday, and they're the people most likely to be concerned about its impact. Now the iPod will join digital video recorders and DVDs as another way of seeing television programs other than their regularly scheduled times on the ABC stations.

Leon Long, chairman of ABC's affiliate board and general manager of WLOX-TV in Biloxi, Miss., wasn't worried.

He said if viewers have the choice of watching "Desperate Housewives" on their wide-screen television with surround sound or a two-inch iPod screen, they will almost certainly watch it on TV. The iPod option will likely be attractive to people who missed an episode and want to keep up with the story, he said.

Portable Mp3 Player Based Education

2009-01-28T20:00:00.001-08:00

Writen by Bal Simon

A revolution in learning technology has taken place. Actually, it took place a few years ago, and I'm only just now catching up. The reason is that no one connected the dots for me, and I guess I'm a bit slow. :)

That's the value added I'm giving you here today. I'm connecting the dots for you, in case you haven't yet made the connection.

MP3 players have become huge business. The most popular of these, of course, is the IPOD, but you can find many other brands with lots of different features to select from.

They mainly get used for entertainment purposes - listening to music on the go, hearing podcasts by your favorite artists, and so forth.

But the real revolution for upwardly mobile people is in having portable education that you can take with you most anywhere.

I got, as a birthday gift, Creative's MuVo TX FM. If you get this one, and if you have ears anything like mine, be prepared to spend another $10 to get a decent set of headphones, because the ones that come with it physically hurt my ears. Not permanently - just a bit of temporary pain. And since I'm not into avoidable pain, I went to my local Radio Shack and got their "Three-In-One" package - which includes 3 sets of headphones for, like I said, about $10.

OK - so having an MP3 player is "dot" number 1.

"Dot" number 2 is that you can find huge numbers of MP3 audio files for instruction on almost anything. And you can download these files to your computer. And from your computer, you can transfer these files to your MP3 player.

For example, from one of the membership sites I in which I participate, there is an mp3 file of an interview of Brian Keith Voiles, an acknowledged master copywriter. I've had that file on my computer for ages. Never got around to lisening to it.

Now it's on my little MuVo and I've started listening while - well, I'm getting ahead of myself. Let's go to ...

"Dot" number 3 is that you can get an adaptor (I got mine, again from Radio Shack) to let you play these audio files in your car over your stereo speakers.

Beautiful!

Now as I drive around doing errands, I can absorb in the convenience of my car, wihtout breaking any laws, information from copywriting experts or from self-help coaches, and more.

I spend a fair amount of time in the car, so this really increases my productivity.

But we're not done yet...

"Dot" #4 - My little MuVo enables me to go to bed, and continue listening as I drift off into the Land of Nod ... without disturbing my wife!

I can walk around the house, go work out, and all kinds of other sundry things - and continue learning.

Finally - the unit I bought also enables me to record ideas on the fly and play them back. I haven't fully tested this yet, so I'm not sure about the audio quality - is it suitable for playing to you on my website? I'll be experimenting and report back to you.

The MuVo that I got costs about $149 plus whatever tax and shipping applies. Add the new headphones (a must, I'm sad to say) and the car adaptor, and you're looking at a total expenditure of about $180.

That may seem like a fair amount of money, but if you spend a lot of time doing mentally deadening things like driving around doing errands or working out while the gym plays the latest in so-called music so that you can't think - well, this may be an incredible value.

I can recommend the MuVo (depsite the headphones), but shop around. Lots of folks vouch for the iPod. And others for something called Zen. You'll find lots of options, including price. Something is bound to work for you.

And once you have it - watch out. You're brain may just explode with the new wealth of information you'll be painlessly absorbing.

Your Hard Drive Is Going To Explode Why A Ups Is Essential

2009-01-27T20:00:00.001-08:00

Writen by Kevin Souter

It's most peoples worst computing nightmare. You wake up in the morning, flip on the computer, and it doesn't boot. Sometimes the problem rears its ugly head as a horrific clacking noise. Other times it simply gives a read error.

At this point, most people panic. The first thing you wonder is whether or not the data is recoverable. There is no universal answer to this. In some cases, a simple scan with some data recovery software is all that it takes to retrieve the contents of the drive. In other cases, if you want it badly enough, it will take thousands of dollars and a shipment of the drive to a clean lab where they will pull the platters inside of the drive and access them that way.

Now you're probably wondering if there's a way to prevent this from happening. Well, you're in luck. Getting a UPS (Uninterruptible Power Supply) is the very best and most effective way to prevent your data from pulling a disappearing act.

While it is not fool-proof, having something that regulates the electricity flowing into your computer can reduce the risk of a drive failure by up to 70%. This figure goes up to around 90% if the computer is being used while in an electrical storm. (My computer repair business always gets a little boost after a thunderstorm, courtesy of the lightning wreaking havoc on people's hard drives.)

Don't just run out and get any UPS. You want to get an intelligent one. The 'intelligent' UPS will regulate the power without having to hit the battery every time the voltage takes a dip which greatly improves battery longevity. They also include options to hook the power supply up to your computer via a serial or USB port so you can monitor what the power is doing. This also gives the option to allow for a soft shut-down if the power goes out and you are away from your desk.

You can get an Uninterruptible Power Supply at most computer stores. Best Buy carries a fairly wide selection of them.

As for brands, I've personally used APC with much success. Opti-UPS is another excellent brand. In fact, I have an Opti that is 6 years old and still works fine, although the batteries now have no life to them. (That's to be expected. Rechargeable batteries only last so long)

Now that you know of the importance of a UPS I would strongly encourage you to invest in one. It is far better to spend $100 now on some preventative maintenance than having to spend much more later on data recovery.

A Market Study Of Colour Printers

2009-01-26T20:00:00.001-08:00

Writen by John Sollars

The printer manufacturing market seems to be a booming one. Manufacturers are no doubt eyeing expansion and coming up with newer products to capture the burgeoning market. The manufacturers are interested in the colour -printer sector for purely reasons of expansion. There is stiff competition between the makers as all are concentrating to keep the prices low to capture the market. It must be said here that while in the monochrome department Hewlett-Packard co. are the market leaders, the reigning company in the colour segment still remains undecided.

However the future of the colour printer market is purported to be a bright one according to those investing in these companies. The investors are much optimistic, as these printers, using four times the toner cyan, magenta, yellow, and black of a monochrome printer, will produce pictures of a much higher quality. The market, currently a billion dollar industry, will increase manifold.

Adding on to its product range, printing giant Lexmark introduced its c52x series, which included the c524n last June. Earlier there was a huge gap in its colour line up-there was simply the low- end c510 with a capacity of printing about 8 colour and 30 monochrome pictures in a single minute which wasn't all that fast. There also existed, side-by-side, the high-end c762 which, though having a higher speed, was much more expensive, thereby difficult to afford for the smaller offices and home users. As there was no other product catering to the demands of the users the competitors of Lexmark had an edge over it.

The introduction of Lexmark's c524n however changed things. They introduced this product with a very low price range, thereby making it affordable. Offering a dpi resolution of 1200*1200, this network ready colour laser printer has an outstanding colour output and can print up to twenty pages per minute. The very first page may be printed in as little as 13seconds. The model has a monthly maximum duty cycle of 65000 pages, which is quite impressive. The new c524 also reduces the time taken by print jobs considerably as it has a 437.5MHz processor and 128Mbytes of memory. The memory can be expanded up to 576, which decreases the waiting time taken for print jobs. Moreover, colour care technology and Lexmark coverage estimator help in managing the cost involved in using colour toner. The model, weighing 57 pounds, is 17.3 inches wide, 19 inches high and 20.2 deep. With the model also comes a CD consisting of the user guide and the printer software, a power cable, a paper exit extension tray, set up sheet and toner cartridges for cyan, yellow, magenta and black. The product has a one-year warranty period for on site repair.

It goes without saying that that outsourcing of IT and consumer electronic products lower manufacturing costs of the product, which helps lower the prices of the produced good. The question is how low must the producers keep their profit margins in order to stay in the race in today's colour printing market?

The current analysis lab examined the c524n at a product volume of 1,20,000 units under the assumption that the model was produced in china. An analysis was made of the procurement costs of commodity components, manufacturing costs of fabricated components and location labour rates. The production cost was estimated to be around £265 / unit. The cost distribution showed the cost of the printer mechanism and its assembly to be about £51. The electronics and assembly account for £60. Other costs included laser power supply, consumables assembly, fuser assembly, paper assembly, control panel assembly electronics assembly, final arrangements, etc.

At the time of launching the product, the product was supposed to be priced at £390. However, Lexmark priced the product at almost half of the originally intended price at some places. To maximize its revenue, the company in a clever move, outfitted the toner with different toner cartridges. The toner content was increased or decreased according to the budget of the customer. The more expensive models containing more toner catered to the demands of the enterprise segment while the lower priced models with low yield cartridges were ideal for small offices and also home users.

The product, being suitably priced, was a great success, perfectly fitted to meet the needs of the buyers and the manufacturers and compete with its competitors in the lucrative colour printer market. Lexmark claimed the print quality was Photorealistic. On account of its chemically processed, spherical toner delivering a 1200*1200 dpi resolution and also because the new print head four lasers in one unit with a mirror. The machine enabled Lexmark to take on the enterprise market as well as their competitors, especially Hewlett-Packard.

Printers What Really Happens When You Hit Quotprintquot

2009-01-25T20:00:00.001-08:00

Writen by Bill Smith

You just poured hours upon hours into a lengthy research paper. All that's left to do is print it out. And that's the easy part, right? Sure looks easy from the user perspective, but it's actually quite complicated. A series of critical processes kick off as soon as you kit the OK button.

The first thing that happens is your software application (MS Word, Excel, etc) sends the data you want to print to your printer driver. The printer driver is nothing more than some software that translates data into a format that your specific printer can understand. When you buy a new printer, it generally comes with a CD. On that CD is the printer driver software you need to enable your specific printer to talk to your computer.

The printer driver takes the translated data and physically sends it along to your printer. It's able to connect to the printer via the USM connection interface. Much of the data received by the printer goes directly into the printer buffer, where it is stored. By storing the data within the printer itself you're able to finish the print job quickly.

If you just turned your printer on for the first time in a while or if the printer has been standing idle for a while, the printer will run through a series of diagnostic tests. Some of these tests check he availability of ink, while others clean the print heads.

Once this preprinting step completes, your printer brain sends a message to the paper stepper motor telling it to engage the rollers and feed paper into the printer body. As the paper is being fed into the machine, the belt pulls the print head into "ready" position. When the paper is perfectly positioned, the print head goes to town, firing droplets of ink at the paper. With incredible speed and accuracy, the print head travels back and forth across the page spewing colors. When it reaches the end of the page, the stepper is quickly engaged, advancing the paper forward. This process continues until the print job is complete.

Making The Right Decision About Toner Cartridges

2009-01-24T20:00:00.001-08:00

Writen by Chris Robertson

The prices of inkjet printers and laserjet printers have never been lower. Similar to video console manufacturers who sell gaming consoles at below cost, knowing that they'll make enormous profits from the sale of video games, manufacturers of inkjets and laserjets sell their products at a low cost, knowing that they will profit tremendously from the sale of inkjet and toner cartridges. Indeed, it's been said that you'd have to spend over $5 billion to fill a swimming pool with ink from manufacturers' cartridges.

The expense of the cartridge is compounded by the growing use of inkjet and laserjet printers. The popularity of digital cameras has grown exponentially in the past five years, and consumers are increasingly opting to print out their digital photos at home. Businesses are utilizing desktop publishing software and high quality printers to produce brochures and marketing materials that they would normally send out to be printed. Likewise, everyone from scout troop leaders to health educators are using available technology to tailor educational content that can be printed on the fly using inkjet and laserjet printers.

This means that the market for inkjet and toner cartridges is booming. It also means that, in order to make an informed decision, the consumer needs to understand the emerging issues in the cartridge wars. To wit:

Black and white vs. color: When you go to buy a printer, you may be stunned at the number of brand options, which include InfoPrint, DocuPrint, WorkCentre, OfficeJet, Optra, and more. If you're primarily going to print documents, a printer with only a black cartridge will suffice. If, on the other hand, you're planning to regularly print photographs or brochures, a color printer might be a better option. If you decide upon a color printer, you'll further be able to choose from among printers that have a four-color cartridge, a six-color cartridge, or even more colors.

Manufacturer's brand vs. generic: Some manufacturers insist that only their proprietary cartridges are optimized for your printer. On the other hand, there are many who view that stance as simply a way for manufacturers to rake in the dollars, and who say that refilled or generic cartridges perform the same function for less money.

The coverage question: Many consumers experience sticker shock when they buy replacement cartridges for their inkjet or laserjet printers. Depending upon what you print, you may be in for a greater shock when your cartridge runs out of ink in a very short time. Typically, when a cartridge package indicates that the cartridge will print a certain number of pages, the assumption is that only five percent of the page will have ink on it - typical for a word processing document. If you're printing pictures, though, you're getting ink coverage of 100 percent, so your ink cartridge will run dry much more quickly.

Paper vs. ink: When it comes to ink cartridge quality, your photo or document will only look as good as the paper it's printed on. This especially applies to photos, where poor paper can cause an image to look muddy.

Webcam How To Choose

2009-01-23T20:00:00.001-08:00

Writen by John Wright

With the growing availability of high bandwidth internet connections getting a webcam and staying in touch with friends and family has never been easier.

What is a Webcam
A webcam is a small video camera that takes still or moving images and sends them to your PC via a USB cable. The quality of image capture is determined by the webcam's lens, optical sensor and the frame rate the camera can transmit.

The best available resolution is 640x480 and the frame rate is almost always 30 frames per second. If your looking to take movie clips then you will need a camera with a high resolution and frame rate. If you want to use your video camera for video conferencing, you could go for a cheaper, lower-spec camera but with the ever increasing availability of high bandwidth internet connections and VoIP software such as Skype, I would recommend going for a good quality camera.

PC specification and your Webcam
At this point it would be a good idea to check the minimum specification required to run the webcam of your choice, and whether your PC meets that specification. The majority of current webcams require at least Windows 98 Second Edition to work properly. Minimum processor requirements generally vary from 350MHz to 700MHz but I would suggest a processor speed of at least 1000MHz. RAM specifications vary from 128MB to 512MB. Manufacturers of webcams will generally state a wide compatibility specification, however, a good rule of thumb would be to take the top specification mentioned for your webcam and use that as your minimum specification requirement.

Ok your PC has met the minimum RAM and Processor specification for your webcam, the next thing to think about is the kind of port your webcam is going to plug into. The majority of webcams manufactured in the past five years plugs in to a USB port. However, there are two kinds of USB ports older USB1.1 ports (12Mbit/s) and the more recent USB2.0 ports (480Mbit/s). These two types look identical and you can plug a USB2.0 port into a USB1.1 socket and you can plug older USB1.1 devices into a USB2.0 port, however, only a USB Hi-Speed device on a USB2.0 port will transfer data faster than 12Mbit/s.

Upgrading your PC to meet your webcam requirements
Before you undertake any upgrade, you need to compare your PC's specifications to the minimum requirements of the webcam you want to install. Check out the need to know below before you take the plunge.

A webcam's manufacturer will specify certain minimum requirements that your PC should meet if it is to work successfully with the device. These generally include the version of Windows on your PC, your processor's speed and the amount of RAM fitted.

Some webcams use a USB Hi-Speed connection. Before you buy one of these cams check to see if your PC has USB2.0 ports. If your PC runs a version of Windows older than XP then it almost certainly doesn't have USB2.0 ports.

Most current webcams come with a built-in microphone, but a few don't. Before you buy, check to see if your webcam has a microphone, if it doesn't you'll have to buy one that plugs into your sound card.

Dvd Replicationwhat You Dont Know Could Give You A Free Pass To The Jailhouse

2009-01-22T20:00:00.001-08:00

Writen by Teresa Tam

DVD replication has come a long way recently. I could recall the times when I started burning CD-R's. Back then, It would take close to an hour to replicate only one CD. Now, I could put 6 times the amount of data into a single DVD in less than 1/6th of the time. With the advent of the internet, there was so many things to download. With all the freedom online, there have been more legal concerns with DVD replication.

The way the law is, you have the right to own and use your DVD replication equipment. However, it's what you do with it that may burn you. DVD duplication can become a very big legal issue. So whether it's a movie, some music, or any time of image, video, or audio, you have to determine if it is in fact copyrighted. If it is, you have to get permission from the owner to duplicate it. There are also cases where you must pay to duplicate the media. This can be in the form of a royalty.

Now what happens if you legally own the DVD? Should you have the freedom to do what you want with it? That are some fine guidelines that you must follow. Let's say that you make a copy of that DVD. In this case, you are not breaking the law. You are legally permitted to have a backup for your own personal purposes. Especially if it's a rare DVD - you can have a copy in case you're afraid that something might happen to the original.

So far, that's only part of the story. Again, that duplicated DVD is for your "personal" use. So what if you decide to let a friend borrow that DVD. You have now breaking the law.

Don't take this lightly. I knew a friend that came back from China. At the time, there were tons of bootlegged DVD's. You could find thousands of blockbuster movies that were recently released in the U.S. cinema. This person ended up buying four of these DVD's and packed them in his luggage on his trip back to the U.S.

When he arrived at the airport, they discovered the bootlegs. To make a long story short, he was fined $10,000 for each DVD. So that was a total of $40,000. Who knew if those movies were great or not. It wasn't worth that huge penalty. In fact, he had to sell his home to pay off the fine.

Now that you're informed, it is now up to you to make an educated decision. If you decide to duplicate copyrighted DVD's that you own, make sure that you don't loan them out. You never know what will happen once it get's out of your hands. Even if it's a friend that you trust, who knows if it will be viewed or seen by a person who you don't trust?

Wireless Headsets

2009-01-21T20:00:00.001-08:00

Writen by Josh Riverside

Wireless headsets are headphones that are not physically connected to the main device with a wire. These headsets use radio or infrared waves to receive signals from the main source. They provide extremely flexibility to do anything while wearing them-walk, jog, skate or even ski.

Wireless headsets are becoming fairly common even for household use like watching TV or listening to music. Since they are not connected by cords to the main equipment, they allow flexibility to move around and do things like cooking, exercising or any other household chores.

Some wireless headsets use infrared rays for receiving signals, like a remote control. These have a limited range of receiving of a maximum of 30 feet. Cordless headphones, on the other hand, use radio waves. The headset should be adjusted in frequency with the base station so as not to interfere with other devices. These headsets have a greater frequency of up to 2.4 GHz and can reach up to 300 feet.

When buying a wireless headset consider the following: is it comfortable? Does it stay securely in place for long hours? Is the microphone flexible and unobtrusive? Are the volume and other controls easily accessible? Is the sound quality on both the lines clear?

Most wireless headsets these days come with advanced features like standard/voice tube/ noise canceling, the solution type (telephone use/ mobile use/ headset adapter/headset accessory), the kind of ear piece (monaural/binaural), the kind of phone or computer connection to be used with the headset (Bluetooth, USB, 3.5mm/ Analog), the compatibility (to music), the kind of computer usage (VoIP, Computer Gaming), the range of bass/treble, the speaker power, etc. The kind of battery should also be considered since the length of use is dependent on the strength of the battery. Some wireless headsets use rechargeable batteries.

The leading manufacturers of wireless headsets are Plantronics, GN Netcom, Headsets.com, Sennheiser, Jabra, and Sony. The Internet is a good source for locating the ideal wireless headset. There are several web sites that provide comprehensive information about the wide range of wireless headsets available in the market today. Manufacturers also provide the support of online specialists to help you select the best headset, including discounts and warranties.

Toshiba Offers You More

2009-01-20T20:00:00.001-08:00

Writen by John Gibb

One product area that Toshiba has been doing very well in lately is the DVD player market. This includes normal DVD players and recorders that hook up to a TV, DVD drives that go inside computers, and portable DVD players that can be used to watch films on the go.

When it comes to TV DVD players, Toshiba was part of the original DVD working group that worked together to come up with the format, and had some of the first players on the market. Unlike the cheap clones that have since come out of the Far East, Toshiba DVD players implement the standards consistently and reliably, making sure that all DVDs will play, all the extra features will always work and the picture quality will be the very best that the disc can manage. Although Toshiba DVD players can be expensive, their reputation is second to none, and they are considered by many home cinema fans to be some of the best players available at any price.

Given its mastery of the high-end DVD player market, then, it is understandable that Toshiba has made moves to expand its product offering in this area. As recordable DVDs came on the market, Toshiba was again in the working group and one of the first companies to offer the product. The same goes for portable DVD players, where Toshiba was at the forefront of building a market for them, combining the great DVD playback of their DVD players with the build quality and light weight of their laptops to come up with some of the best portable players out there.

Finally, if you're thinking of buying a new DVD drive for your computer, you would do well to consider getting a Toshiba. Toshibas tend to be able to read DVDs slightly faster than some other brands, and are much more reliable when it comes to burning discs. They are a favourite among computer enthusiasts, as they can copy some discs that other players can't, making them especially good for making backups of copy-protected commercial software.

Led Lighting Modules Taking The Heat Out Of The Situation

2009-01-19T20:00:00.001-08:00

Writen by James Stratford

The appeal of using LEDs in lighting applications is growing rapidly. The numerous and significant benefits of using modules that incorporate a matrix of LEDs are being recognized by design engineers in several key industry sectors, including aerospace, architectural lighting, and the "golden egg" automotive market.

Attributes such as design flexibility, low power consumption, even and reliable light, and long lifetime distinguish LED modules from designs based on traditional filament lamps and fluorescent tubes. LEDs can also have knock-on benefits, such as greatly reducing the size and complexity of the module and simplifying the lens design.

A good example of some other benefits of LED lighting is demonstrated by an application in the cabin of a passenger aircraft. A retrofit LED unit that replaced a fluorescent-tube lighting module enabled finely controlled dimming and also provided mood lighting through the use of differently coloured LEDs.

Thermal management

Perhaps the most challenging issue when realizing a module design that uses LEDs is to manage the temperature of individual device junctions during normal operation. If the considerable amount of heat produced by all the devices in a module is not managed correctly then the junction temperatures may reach a level where the LEDs' expected life is shortened and reliability is compromised (see Links).

LED modules typically comprise a matrix of many surface mount devices. These LEDs are soldered to an etched copper layer that provides the interconnects between the individual LEDs as well as other passive and active components that are required to complete the circuit. The small size of the LEDs and the close proximity with which they can be mounted means that designers have a huge amount of design freedom and can achieve complex lighting patterns with high levels of brightness.

The etched copper circuit is separated from a base plate usually made of aluminum by a thermally efficient, electrically isolating dielectric material. The characteristics and capabilities of the dielectric layer are key to the design flexibility and performance of the overall module.

Dielectric materials are made by blending thermally efficient materials such as alumina and boron nitride with other ingredients, to provide a flexible yet resilient coating on the base plate. An important characteristic of the dielectric layer is the amount of electrical isolation it provides between the copper on the topside and the metallic base plate on the underside. This is known as its dielectric strength. A typical dielectric material may possess a dielectric strength of around 800 V/mil and be coated onto the base plate to a thickness of 812 mils (1 mil = 1 inch3 = 25.4 µm).

Dielectric materials used on insulated metal circuit boards usually have a thermal conductivity figure in the region of 3W/mK. This is approximately 10 times the performance achieved by FR4 (flame retardant woven glass reinforced epoxy resin) PCB material.

A further key requirement of the dielectric layer is to be able to compensate for the different coefficients of thermal expansion of the copper track on the topside of the assembly and the aluminum base plate/heat spreader on the bottom side.

Going three-dimensional

Flat sheets of insulated metal circuit board comprising copper foil, a dielectric layer and an aluminum base plate have been available for several years. In the eyes of the forward-thinking LED module designer, the main problem has been that flat sheets of insulated metal circuit board limit them to 2D shapes.

To address this limitation, new dielectric materials are becoming available that have a low modulus, meaning that they are compliant with mechanical stress and strain. These materials not only accommodate the coefficient of expansion of the metal elements of the construction, but also enable parts to be formed into right angles, and even through 360˚. This enables designers to realize complex-shaped designs and ones that form a complete circle with either internal or external copper traces.

When designing with new, formable insulated metal circuit board materials it is possible to route the tracks around corners, which alleviates the need to use connectors and hard wiring. There are several benefits to this, including enhanced reliability resulting from having fewer junctions and interconnects. Despite the slightly higher cost of the new materials, the overall cost is reduced because fewer components are needed, and assembly time is reduced.

Strength and durability

LEDs themselves are inherently durable. Mounting them on metal based circuit boards only serves to enhance their robustness and that of the finished module, providing excellent resistance to vibration and mechanical shock.

Automotive lighting clusters provide a good example of how LED modules can provide superior performance compared with traditional filament lamps. On-vehicle applications experience high levels of vibration and wide operating temperature ranges that can cause premature failure of filament lamps. In some operating conditions LEDs can last up to 100,000 hours, which means that they should not require any attention for the life of the vehicle.

The long life of LEDs also simplifies the designers' task because it is less important to make the lighting module accessible for servicing in the finished product. This can result in a neater, more integrated installation and also in potential cost savings.

Temperature modelling

Thermal analysis software packages are available to help prove LED based module designs before they are committed to manufacture. These software packages gather data from an integrated database about LED performance and specifications along with those of other devices that are mounted on the insulated metal circuit board. This data is combined with other information about elements of the design, including the copper traces, power and ground planes, and vias. The collated information is then processed to produce an accurate representation of the thermal performance of the design.

User-friendly graphical representations of the results enable the design engineer to quickly pinpoint areas that may require attention, right down to component and track level.

Thermal analysis software can bring significant commercial and design benefits by helping speed the time to market and reducing the number of iterations needed to reach a production-ready solution.

Printer Cartridges

2009-01-18T20:00:00.001-08:00

Writen by Elizabeth Morgan

There are so many different printer cartridges available. It is up to you to decide which one is most suitable for your printer. When you buy a printer cartridge, make sure you take into account the cost involved in replacing the cartridge.

Printer cartridges come in two types: the combination print head and the ink reservoir cartridge. The combination print head is not economical because the print process is controlled by set circuits and these have to be replaced with every ink replacement. Moreover, they can be refilled only once.

The ink reservoir cartridge is considered economical as the print head is not within the cartridge thereby saving a basic expense. The design is such that compatible units can be produced. Inkjet printers use thermal technology and go by the name of bubble jet printers. Laser jet printers are based on static electricity and the quality is superior to inkjet printers.

While using printers, keep in mind that they should be serviced regularly, that the paper used should be of good quality and that correct installation techniques and aligning instructions are followed.

If you are buying refilled cartridges, look for OEM or original equipment manufacturers like Canon, Epson, Brother, to name a few. The company's name on the product is a sign of its authenticity. Generic cartridges give high quality results and are reliable and they are a cheaper option to their branded counterparts. Some names in this field are Hewlett Packard, Compaq, and Lexmark. Remanufactured cartridges are basically recycled cartridges which pass the required test for proper use.

It is necessary to have some knowledge about printers and their use regarding printing output and cartridges otherwise one may end up buying the wrong cartridge. Since cartridges come in different varieties for different jobs, one must have a clear idea of one's requirements. Accessories can be quite expensive so good research before buying a printer would go a long way in keeping within your budget.

Guide To Buying A Desktop Computer

2009-01-17T20:00:00.001-08:00

Writen by Andrew Gates

With the rapid pace of technological developments, nothing has become as ubiquitous as the computer. Everyone's got one. And they are used for all manner of endeavour, by people of all walks of life. So, do you simply buy the computer that someone's selling? Or do you do some homework and figure out what detailed specifications are going to make some difference to you?

At Myshopping.com.au you can compare the prices of a wide range of different computers from different vendors and of different specifications. This guide will help you find what you're looking for.

Mac or Windows (PC)

At the outset, you need to decide what you are going to use the computer for. This will help you make the fundamental decision of whether you should go Mac or PC. Although, with the advent of the dual core processor (an Intel chip now used by Mac) the differences are narrowed a little, there are still some choices that can help you favour one system over another. Historically, Mac computers have a reputation for greater stability that comes from a more robust operating system than Windows based computers. Largely for this reason, Macs have been the computer of choice for the graphic design industry, the music production industry and the video production industry. This has prompted the software manufacturers to make professional software packages for these disciplines that favour the Mac operating system. Although they have packages supporting the Windows operating system, they are often less capable.

Consequently, if you are engaged in these industries and need your computer for this type of work, you should consider Mac. Mac computers appear to attract fewer viruses and software malfunctions than do Windows based PCs. On the down side, there has always appeared to have been limited software support for Mac systems.

Another decision that may guide your choice is the aesthetics of the computer. If you have limited available space, there is nothing quite like the iMacs or the mini Macs for space saving. iMac's all-in-one desktop units are compact and complete with all the connectivity you need. However, the look of other brands may be more to your taste, with many models available in compact packages and modern colour schemes to suit practically all dйcor. Now that you've made that basic decision, you can start comparing the apples with apples.

The Components of Your Computer

The two factors that determine the price of your computer are size (yes it does matter) and speed. Either or both of these two dimensions are a factor of practically every component that makes up the machine. Naturally the highest price tags go with the combination of biggest and fastest.

CPU
The heart of the computer is the CPU (central processing unit). You need to decide which CPU you want driving your computer. These come from different manufacturers, and the current development of the technology is called Dual Core, which means that there are two processors on the one chip. Dual Core technology delivers more performance with less energy requirements. Intel and AMD are the two leading CPU manufacturers, and they offer different products under different names.

Current processing speeds range from about 1.4 GHz (gigahertz) through to 3.46 GHz. But it is not simply just a matter of speed. There are other considerations. Mac Operating Systems have a different architecture to Windows and will perform many functions faster with a slower speed CPU. A dual core chip at 1.4 GHz will deliver a better performance that a Pentium 4 chip at 1.8 GHz. A 1.4 GH dual core chip running a Mac with OSX Tiger, will perform better than a 2.0 GHz Pentium 4 processor running Windows. You need to decide what you want your computer to do, what your major software requirements are before you decide on the CPU processor.

However, for everyday use, a processor faster than 1.8 GHz will deliver excellent performance. As a rough rule of thumb, choose a Celeron for low cost computing, a Pentium 4 for mid-range budgets, or an AMD Athlon for bigger budgets. You can compare computers based on Pentium, Celeron, Athlon or Dual Core CPUs by searching those specifications on Myshopping.com.au and finding different vendors and brands using different processors.

RAM
This is where bigger definitely means better performance. RAM is the system memory that enables the computer to use its programs and swap data between the hard drive and the program functions. It's important to match the speed of the RAM of your computer with the speed of the CPU. The more RAM you have available for your programs to work, the faster will your computer run. Most computers today come with at least 256 M (megabytes) of RAM. But memory is a relatively cheap component, and it costs little extra to upgrade to 512 M or greater.

HARD DRIVE
For a detailed explanation of hard drives, please see the article on Myshopping.com.au dedicated to Hard Disc Drives.

The hard drive of the computer stores your program files and your data. As computers have advanced, so has the need for more capacity to operate programs and store data. People working in media fields tend to work with very large files and require large storage space. Most computers in today's market come with a minimum of 40G of hard drive space. However, this can be upgraded (usually in 20G chunks) to as much as 200G or more. The effectiveness of your hard drive also can depend on its physical speed (5400-7200 RPM) and the speed at which it can transfer data between the computer's RAM and the hard drive. Faster means better performance.

REMOVABLE MEDIA
You will want to have a CD-R or (CD-RW) drive installed in your computer, and or possibly a DVD or DVD-R. For reading a CD ROM, all that is required is a CD drive and for watching DVD movies, a DVD ROM drive. However with a CD-R drive, you can record your own data and music CDs, and with a DVD-R drive, you can burn files in a DVD format, allowing you to store movies and data in far greater quantities. The CD-RW (DVD-RW) drives allow you to use re-recordable media. Your decision will depend on what you want to use your media drives for and what you want to store.

Other removable media will possibly include flash card storage, which is usually plugged in via the USB ports on the computer.

MONITORS
For a detailed explanation of monitors, please see the article on Myshopping.com.au dedicated to Monitors.

The monitor for your computer is integral to its function and aesthetics. If you are working in graphics you may want to stay with a CRT monitor. However most bundle offers these days are supplied with LCD monitors, which have the advantages of smaller space requirements, use lower energy and offer wider screen images. However they generally are more expensive (although prices are dropping everyday), can frequently be not as bright, have limited viewing angles and sometimes require a digital interface connector.

For graphics intensive work, LCD screens do not have the same capacity to render colours in gradients as CRT monitors. Once again, size matters. Bigger screens cost more than smaller ones.

VIDEO AND SOUND
For a detailed explanation of video cards, please see the article on Myshopping.com.au dedicated to Video Cards.

The interface between the CPU and the Monitor is provided by the video card. One of the basic decisions you need to make is whether you require a 3D or 2D card. Video cards come in two different types: those that use an AGP (accelerated graphics port) on the computer motherboard and those that use the PCI bus. Data transfer rate is critical to video performance. Faster video cards use an AGP, and this proves a faster data transfer than PCI cards. Most video cards also have their own video memory installed on the card, a feature that increases a computer's memory performance. Today, these memories are often 128M or 256M, and can be more in the higher-end cards dedicated to sophisticated video work or gaming. Video cards performance is also affected by what is known as clock speed or clock rate, cards with a faster speed offer faster performance.

Cheaper computers, and laptops and notebooks, have an integrated graphics chip included in the motherboard instead of a discrete video card. This type of configuration is not as powerful or as fully functional as having a separate video card, which can allow more comprehensive gaming, the use of multiple monitors and faster and better rendering of images.

For a computer to reproduce the sounds recorded in games, movies and music products it requires a sound card. Quality of sound can be affected by the sound card your computer has installed. It's important that you know how you want to use the sound reproduction processes of your computer. If you are a musician and want to record audio, then you will want to be sure that you have excellent connectivity, good midi access and at least 16-bit (CD quality) audio reproduction. Sound cards give you the possibilities of full cinema surround sound, and the many subtle effects employed by high-end games.

Nearly every computer comes with a set of stereo speakers. However it pays to have a good listen to what you're buying. Make sure you listen to program that you are familiar with (take your own CD along) and compare the sound in a quiet environment. Many speaker systems for computers have poor frequency response and are underpowered. For desktop use that does not involve a quality listening environment this may be satisfactory. But if you want to listen to music and watch movies for the full effect, then you need to consider buying a good quality set of speakers. Use the search facility of Myshopping.com.au to compare specifications and prices of different speaker systems.

KEYBOARD AND MOUSE
The choice of keyboard and mouse are personal choices. Sometimes it depends on what you do on your computer, whether you have formal typing skills or whether you're a two-finger hack. Serious writers may prefer an ergonomic keyboard. Keyboards frequently have different clicks and responses to others. You may prefer an infrared cordless keyboard and mouse. You may prefer an optical mouse on which you don't have to clean the rollers. Optical mice have no rollerball, and can be used on most flat surfaces, but they are more expensive.

CONNECTIVITY
Today, connectivity is everything. Your computer can have wireless connections to all of your peripherals: printer, scanner, and other computers. Having an onboard modem will only be really important if you are using a dial up internet connection. Broadband modems tend to be peripherals and you can connect via USB, wireless or firewire. It does pay to consider how you will connect to the internet and other peripherals. It's not always convenient to get behind your computer to plug something in or unplug it. Some sound cards have a front face panel with all the connections you need. The USB ports on Macs are conveniently located. Many PC manufacturers haven't caught on to the fact that it's important for some people to easily access the connections to their computers.

To compare the different bundle offers from different brands, and to compare the different components by their specifications, search the Myshopping.com.au database for exactly the specifications you are seeking. You can compare prices and vendors, and order what you need online with a few clicks.

Dualcore Processor Wars Amd X2 Vs Intel Pentium D

2009-01-16T20:00:00.001-08:00

Writen by Peter Stewart

There's a war going on and the latest battle continues to offer the promise of good prices to consumers looking for the best stuff for their computer.

Since the inception of dual-core processors a little while back the race has been on to see who can get the better chip with this dual-core processor technology.

During the final days of the single-core battles, there was a stalemate between AMD and Intel. Intel's clocked higher but were unable to match the speeds that the AMD managed at lower clock speeds.

The oldest difference between them has been their suitability for specific tasks. AMD have had the gaming sector in the bag, especially in terms of the value for money possible with their lower clocked chips, which could be overclocked to the same speeds as their top models. Intel has the crown for general performance. When it comes to office related tasks, Intel processors are able to outperform AMD chips in these areas.

As the ability to clock the chips any higher became more and more difficult technically, the next step was to just add another core, theoretically allowing twice as much number crunching in a dual-core processor. This is not exactly how it works however.

Modern operating systems and programs have not been designed with multiple-core or dual-core processors in mind. They were designed to make use of one core on one processor. The major expense that went with multiple processor computers was the circuitry needed to split tasks up amongst the processors and sharing cache.

Dual-core processors simply act like two places for tasks to go. Instead of single tasks getting split up and performed in two different places, as is the case with traditional single core processors, single threads get split up amongst the cores. This essentially means that each program gets assigned to a core.

Because of this there is absolutely no increase in speed for gaming from dual-core processor chips. Only once the games themselves have been programmed to take advantage of dual-core processors will there be a difference. This is due to the intensive nature of games and the number crunching needed for intense graphics, which for now cannot be split over multiple cores in dual-core processors.

So back to the battlefield.

AMD were the first to introduce their dual-core processor solution to a desktop computer. This gave them a slight lead over Intel. Despite this, AMD gave people a bit of a surprise with their new offering.

Always having been renowned for giving far more than expected for the price, these new dual-core processors were very expensive. Part of what managed to give AMD a hold in a market previously dominated by Intel was their good pricing. This shock did not go down well with consumers.

To add insult to injury, Intel's dual-core processor offerings came in at remarkably good value. Both of their initial dual-core processors cost less than AMD's lowest priced model. That's right, AMD's cheapest dual-core processor cost more than Intel's most expensive. This definitely put the ball in Intel's court and was downright disappointing for AMD fans.

AMD did manage to introduce a cheaper model to compete better with the Intel offerings. Despite this, Intel was still the forerunner in this area.

Performance remains an area that is sketchy.

With the relatively new technology involved it is hard to draw a clear conclusion on who is faster. With operating systems only recently oriented towards fully utilizing dual-core processor technology, it is still new territory. Both offer increased performance, but as to who will rule the roost, we'll have to see.

For the meantime it would probably be advisable to just watch. Being a cautious buyer I prefer to buy into a sure thing, once things have settled down, prices will balance out and all the related technology will be in place. Then we will be able to get a true opinion on where to put your hard earned cash.

Just The Fax Mam

2009-01-15T20:00:00.001-08:00

Writen by James Snyder

For years, I smugly prided myself as a non-fax machine person. I felt it beneath my dignity to own such a technical contraption. The quill is more my style than a computer but, being practical, I reluctantly use a computer, casting wistful glances at the dust gathering on my quill.

Unfortunately, in the world in which we live, it is necessary to fax some letters or documents to someone in some odd part of the world. I don't like it, but that's just the way it is.

On the rare occasion when I must fax some document at an office supply store, I usually sneak in the back way. It has been my experience, when the fax man seeth me cometh, he always raises the price per page. This is just a small service he does for Yours Truly.

Then, when paying for this service, the fax man usually says with an impish grin, "When are you going to get a fax machine of your own?"

I always flash a smile back at him, but if he knew the thoughts in my head, he would charge me more per page. Silence truly is golden, especially for the person exercising the virtue.

Actually, I don't trust machines. I know a mind somewhere is controlling all of these machines a menacing, mischievous mind dedicated to the simple task of messing up my life.

When I eventually break down and buy a fax machine someone will invent something to replace it and I'll have another antique on my hands to put alongside of my Underwood typewriter and boxes of 8-track tapes.

This notwithstanding, I ended up buying a fax machine several weeks ago. I didn't want to, but I had no choice in the matter.

My printer finally went the way of all printers. I hated to see it go. The left side was cracked where Noah, the original owner, dropped it. For years, it served me quite well. My next printer will have a big ink cartridge to fill.

I hate buying replacement equipment. Rarely is the new any better than the old, just more expensive, not to mention complicated. But, necessity is the stepmother of all complications in life, and I set out to buy a new printer.

I resolutely did not want to buy a fax machine. Under no circumstance did I want to buy a fax machine. Therefore, I ended up buying a fax machine.

It is impossible to buy a printer anymore. In order to buy a printer you must buy a machine that prints/copies/scans/faxes. I think it's a pretty sneaky way to get me to buy a fax machine. Someone "out there" is set on me owning a fax machine even though I don't want to own one.

This new machine does everything but vacuum the interior of my car. But it was the cheapest machine I could find.

I bought the machine but determined not to use the fax part. After all, somebody has to stand up for what they believe. Not everybody should succumb to the latest trend.

I was doing fine until ending up in the hospital. When I got out, I needed to fax a document to the hospital. Now I faced a taxing dilemma.

Do I go to the office store and fax my document, or do I try out my new printer/copier/scanner/fax machine?

Precedence finally gave way to convenience. I took my document to my new machine and figured out how to fax it to the hospital.

Not being confident in my technical knowledge, I called the hospital office to check on the faxed document. Much to my surprise the person on the other end said in a very cheery voice, "Yes, I have the faxed document right here in my hand."

I must admit, although I hate doing so, faxing from my house was much easier than going to the office store.

I now knew how to fax a document anywhere in the world, but I had nothing to fax to anyone in the world. I just stood there looking at my machine trying to think of something to fax.

Even though I knew how to fax a document, I still did not know how to receive a fax.

Several days ago, a friend called and said he had a document he wanted me to have right away. He then asked the ominous question, "Do you have a fax machine?"

I began to say no, but hesitated and confessed I had a fax machine but did not know how to receive faxes. It was humiliating to make such a confession, but it was true.

"It's simple," he said, "hang up the phone and I'll dial again and let the machines talk to one another."

This caused no small discomfort. To think these machines are talking to one another behind my back is most disturbing. What are they saying about me behind my back?

Now that I come to think about it, I have heard sounds similar to snickering coming from the general direction of my printer/scanner/copier/fax machine. I don't mind Big Brother watching over me, but I do mind some machine making jokes with other machines about me.

When it comes to "new things," God is the master. This is what He promises to do for us. "Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new." (2 Corinthians 5:17 KJV.)

Put that in your printer and fax it.

Advantages Of Discount Laptops

2009-01-14T20:00:00.001-08:00

Writen by Jimmy Sturo

Used or refurbished electronics are better than new ones for some excellent reasons. Companies such as IBM, Dell, Compaq, HP, and Gateway are known for making high quality laptop computers. Each company is a reliable manufacturer of quality goods and is highly competitive in the market. Giving the customer exactly what they want, making top-notch products, and offering repairs in cases where the products are defective are a few options to be provided to the customer. Every company spends a lot to advertise their new product. However, when the product is refurbished they do not advertise it, thus saving that money.

Products being reconditioned must pass a thorough examination. After repairing any defect and sanitizing if required, the product is repackaged either by the original manufacturer or a reputable professional outside firm may perform the reconditioning, returning the products to like-new new condition. Every refurbished laptop sold must meet the original manufacturers standards and must maintain high quality standards. Each item is checked multiple times for proper working condition and quality. Reconditioned goods usually have a very low cost of return.

Lots of money can be saved by purchasing remanufactured goods. Savings can go up to 50%~60% of the original cost. A refurbished laptop computer will have the same technology and features as a brand new mobile computing device, except for the price. Refurbished laptops are also offered the best value in extended warranty and support programs. Buying refurbished computers or used laptops allow saving money and still owning a feature-rich, quality computer or laptop with a manufacturer's warranty included.

Some discount computer stores excel in delivering quality, name brand refurbished laptop computers. They constantly have more used laptops, computers, monitors, and printers that have been refitted and approved for sale by manufacturers such as HP, Dell, Compaq, Gateway, IBM, and Sony.

It is suggested to also consider if the LAN card, CD Writer, DVD Player, DVD-CDRW (although these might depend on personal preference), 56K modem, IrDa (Infrared), and Bluetooth are available when choosing a cheap laptop, since they are usually provided with all the present laptops. Also, it is advised to always check the upgradeability of the laptop.

Your Common Questions And Answers On Your Inkjet Cartridges Are Now Ready For Your Review

2009-01-13T20:00:00.001-08:00

Writen by Joseph Mercado

There are so many questions within the printer market which still haven't been answered. No more mysteries. It's usually the most common questions which are frequently asked where people have the most trouble.

On that note, let's get straight to the point and no cutting corners, shall we...

Q1. What is the difference between a new toner cartridge and a remanufactured cartridge?

A. The difference between a new toner cartridge and a remanufactured cartridge is the price, quality, and packaging. The majority of the internal parts are replaced with new parts, reusing only those long life components that are in good condition.

Many new OEM (original equipment manufacturer) cartridges, such as Hewlett Packard or Canon, are also built from new and used parts.

What you will notice is a difference in the outside of the packaging and most importantly, the price of the product. You will save anywhere from 40% with the toner cartridges and up to 80% with the ink cartridges, which is less than OEM pricing.

This reducing un-necessary overhead will result in saving capital. At the same time, you will maintain the highest quality print output to give you phenomenal end results.

Q2. Will using a replacement toner or ink cartridge voids my printers warranty?

A. No, according to all printer manufacturers, using a replacement toner or ink cartridge will not affect coverage under the printer's warranty.

This especially goes for those who purchase extended warranties with their local retailer. This is proven by the following US Congress Legislation.

MAGNUSON-MOSS WARRANTY IMPROVEMENT ACT:

Magnuson-Moss Warranty Improvement Act United States Code Annotated Title 15 Commerce and trade Chapter 50 Consumer Product Warranties 15 Section 2303.

No warrantor of a consumer product may condition his written or implied warranty of such product on the consumer's using, in connection with such product, any article or service (other than article or service provided without charge under the terms of the warranty) which is identified by brand, trade, or corporate name; except that the prohibition of this subjection may be waived by the commission if:

1)The warrantor satisfies the Commission that the warranted product will function properly only if the article or service so identified is used in connection with the warranted product, and

2)The Commission finds that such a waiver is in the public interest.

This means that the printer manufacturers cannot void the warranty on your printer because you use supplies and products manufactured by a third party manufacturer.

We cannot replace a printer nor have it fixed should any problems occur from using a remanufactured or compatible cartridge.

We guarantee our products from any faults and we have not had a single case of a printer being damaged by a cartridge sold by us.

Q3. What do my printer's error codes mean?

A. Your printer can produce a variety of numerous error codes in two-digit format. Please contact Inkjet Surplus, Inc. to diagnose the problem.

Q4. Why does paper keep jamming in my printer?

A. There are simple reasons and complex reasons to why paper can jam in a printer. You will experience paper jams if you use the wrong type of paper in your printer, such as it being too thick, too thin, or laminated with an unnatural chemical finish.

If paper jams occur at the front of your printer, the problem may be more serious, such as a worn-out pickup assembly. The pickup assembly is responsible for feeding the paper from the paper tray into the printer.

It is possible that when using a top load paper feed tray, dust particles can cause the rollers to jam the paper, which will lead into causing streaks when printing.

To avoid paper jams align the paper properly in the tray, and do your best not to load too much paper in at once.

Q5. When should I consider adding more memory to my printer?

A.If your printer isn't printing as fast as its rated engine speed, adding more memory can and may help close the wide area. You will also need to add more memory if you frequently receive memory overload messages when trying to print documents.

Those messages indicate that your documents are too complex, sending more data to your printer at one time than your printer's memory can handle.

"Those who do not ask the questions are those who are ignorant within themselves"

Q6. When should I consider upgrading my printer?

A. As good as your printer may be, there will come a time when upgrading makes sense. For one thing, printers do wear out eventually, getting to a point where the cost of repairs approaches the cost of a new machine.

You may even want to upgrade before your printer's lifespan comes to an end. No matter how much memory you add to your printer, it will never print faster than its rated engine speed, also as fast as the new technology that recent machines contain.

If you or your staff frequently have to wait for the volume of pages you need to produce, then upgrading to a faster printer would contribute to the efficiency of your operations.

As your business changes, you may develop printing needs that your current printer simply cannot handle or perform, such as high resolution, print speed, or paper sizes. That is when it is time to upgrade.

Q7. Our printer can get very warm during printing. Will this indicate a problem or cause my printer to fail?

A.Most printers are sturdy enough to operate for many hours at a time. In the process they do get warm, After all, the fuser mechanism reaches nearly 400 degrees in order to melt toner onto the paper.

That being said, it is possible for your printer to get extremely hot. If its air intakes are blocked or if its air filter is dirty, your printer won't be cooling it properly and could overheat.

Very serious overheating will occur if your printer's fan fails. A strong recommendation to reduce this from happening, purchase a printer that has a high monthly volume or duty cycle that can handle heavy printing loads.

Consider too, that keeping your printer in a cool environment, such as an air conditioner can help keep it cool.

Q8. What does the fuser assembly do, and does it need to replaced periodically?

A. The fuser assembly is located at the back of your printer. After toner has been deposited on the paper, the fuser (which gets very hot) melts the toner so that it adheres permanently to the paper.

If the fuser is not cleaned properly and regularly, it could need to be replaced as early as 35,000 prints. Dirt and debris can damage the fuser by scoring its surface. If you notice a ring around the roller, it may be time to replace the mechanism.

Q9. What is DPI?

A. DPI stands for dots per square inch. It represents the level of intensity as well as quality depending on how many microscopic drops per dot are layered upon each other.

There are directions in which ink is layered, horizontally and vertically. Pixels are contracted together to bring the image to its realistic life looks.

A high resolution such as 2400 x 1200 dpi will result in its best performance on high quality photo paper. DPI is measured on the amount of drops layered on the base of the paper, not the size of the resolution.

Q10. What is the difference if I purchase a printer that contains the print heads built-into the carriage or on the cartridge?

A. The difference is that every time you purchase a new cartridge such as a HP or a Lexmark, you are getting a brand new print head.

Whenever a printer is purchased with the print heads built-into the carriage, the more wear and tear will occur on the print heads within that printer. The cost of having a carriage replaced or repaired can result to the same cost as a new cartridge or even a new printer depending on the manufacturer.

Q11. What are compatible cartridges?

A. Compatible cartridges are specifically manufactured to meet or exceed Original Equipment Manufacturer specifications.

These cartridges offer a high output of quality, reliability, and offer great printing results.

Compatible cartridges are brand new retail boxed cartridges, containing only new components such as OEM product.

They are also an economical alternative to expensive brand name cartridges and supplies that allow the consumer to enjoy big savings. The use of compatible or replacement cartridges does not void the printer's warranty.

How To Purchase A Flat Panel Tv

2009-01-12T20:00:00.001-08:00

Writen by Philip Liu

When purchasing a flat panel TV, there are a few things to keep in mind. Here, we've listed a number of considerations for you to evaluate.

High Definition Upgradeable or HDTV-Ready

If you see either of these terms used when deciding to purchase a flat screen TV, it means that the TV is capable of producing the highest resolutions possible for digital television today. "Upgradeable" means that you'll need to first add a separate HDTV receiver before you can view the pictures in high definition mode (1080i or 720p). But, even if you don't upgrade, the picture will still look fantastic. When watching regular DVDs or TV broadcasts, the picture will be almost as good as real HDTV because most have line-doublers to improve the picture.

16:9 Aspect Ratio

Unlike conventional televisions, new plasma, LCD and rear-projection televisions most likely have a wide, rectangular screen that is very similar to the shape of a movie screen. This is known as 16:9 aspect ratiofor every 16 inches wide, the screen is 9 inches high. Compared to conventional TVs, which are 4:3 in aspect ratio, the field of vision is wider for a new flat screen TV.

When watching DVDs at home on a 16:9 wide-screen television, you will be able to enjoy the full screen effect of the movie the way it was intended. On the other hand, when watching regular, standard definition television (like a news broadcast or talk show), you will need to either set the television to fill the screen entirely or watch with vertical black bars on either side of the picture.

Finally, remember that even though most television broadcasts are in 4:3 format, 16:9 widescreen format is the way of the future. Many events are shot in HDTV format (for example, the Olympics, special sporting events, nature documentaries, etc.) and as more and more people purchase high definition television, all broadcasts will be in high definition within the next few years.

Reverse 3:2 Pulldown

Television shows are usually shot on film at 24 frames per second. When transferred to video running at 30 frames per second, the picture quality is distorted in the translation. New televisions are able to correct those distortions through a series of reconversion techniques which reverse the distortions. The result is a smoother and cleaner picture.

When looking to buy a new plasma, LCD or rear-projection television, look for this feature.

3D Y/C Digital Comb Filter

The 3D Y/C digital comb filter's job is to take the cable signal coming from the wall and separate the color, sound, brightness information into useable information. New plasma, LCD and rear-projection televisions have digital 3D Y/C comb filters that do a pretty good job of this so as to avoid what is know as "dot crawl" where the edges of objects appear rough. In addition, a good digital comb filter will also counter the effects of moiré, where still objects appear to move and ripple.

Most high end plasma, LCD and rear-projection televisions also have component inputs from video sources (such as a DVD player) that separate the signal before reaching the TV and bypass the digital comb filter. This results in an even clearer and brighter picture.

Picture-in-Picture

Picture-in-Picture (or PIP) allows you to watch two shows at once, with the second show in a box in a part of the screen. PIP is fairly common these days to all sorts of televisions. However, consider getting a dual tuner PIP plasma, LCD or projection television since that allows you to watch the second channel without needing an external tuner (for example, from a vcr). In addition, there are also TVs that will show different channels side by sidethese are called twin view PIP TVs.

Inputs

"Inputs" refer to how related audio/visual components connect to your plasma, LCD or rear-projection television. The highest video quality input is known as "component video". With component video inputs, the color and brightness information from the cable is separated into useable data before entering the television. The next best input is S-video input which give a picture almost as good as component videowhereas component video separates brightness, blue signal and red signal from each other, S-video just separates brightness from blue and red signals.

All new plasma, LCD and rear-projection televisions will also have inputs for various multimedia devices such as DVD players. In addition, some will allow you to connect a computer.

Nvidia Graphic Card Ge Force 6600 Gt Review

2009-01-11T20:00:00.001-08:00

Writen by Kirk Jensen

This is an in-depth review of the Nvidia Graphic Card Geforce 6600 GT as it compares to last generation top-notch cards and low-end current tech cards.

(PRWEB) April 17, 2006 -- This review is taken from experts at Anandtech. To start with it is good to distinguish the difference between the AGP and PCI Express versions of the Nvidia graphic card for the Geforce 6600 GT series. First the Geforce 6600 GT for the AGP has an auxiliary power counter, which is not present in the PCI version because it can take up to 75 watts of power from a PCI express X16 slot. Also motherboards are only an option for the PCI slots not the AGP slots.

Until now, we didn't have a good midrange card with the latest technology on it for an affordable price. Those how wanted good performance and a reasonable price went with older cards that where cheap as time went on. This was fine but consumers lost out on staying on top of the lastest technologies available to them with newer cards. This problem is especially present with Nvidi's release of the Shader Model 3.0 support. FarCry is a good example of the lack of Shader Model 3.0 support with older Nvidia graphic cards.

The key marketing factor for the Nvidia Geforce 6600 series aside from it features is its performance and price. All the feature with the Geforce 6600 series promises amazing value.

What Anandech did was a comparison of the latest and most demanding games with a heavy focus on PS2.0 to see how it stacked up against current and previous version of ATI and Nvidia graphic cards.

The Test

As a comparison point Anandech took the ATI X600 XT, but this doesn't give a trully good comparison, the only way to get a good comparison is by comparing both AGP and PCI cards. One such comparison with Doom 3 uses a source engine AGP benchmark which ran on a over clocked Nvidia graphic card FX 5300, so that are not as comparable to the rest of the world.

Anandech felt this was a good setup because of the fact that PCI express systems will have to compete with AGP systems. So as long as the processor has enough power to keep it from becoming a large bottleneck they will have a clue about the graphic cards performance.

The Test Setup

The Geforce 6600 GT did very will and scored in a dead heat with the Geforce 6800 and ATI X800 pro. The games in which the test was done are the following: Doom 3, FryCry, Halo, Jedi Knight: Jedi Academy, and Unreal Tournament 2004.

Doom 3 Performance

The Geforce 6600 GT scores high with the PCI express systems, but falls short compared to more powerful card as resolution increased beyond 1024 X 768 and AA is turned on. The resolution where lower then other test because Doom 3 is a very taxing game.

FarCry

The Geforce 6600 GT scored very well until it hit 1600 X 1200 without AA/AF, with the AA enable it dropped greatly in performance.

Halo Performance

Regardless of the resolution the Geforce 6600 GT scores between the Geforce 6800 and AT X800 Pro.

Jedi Knight: Jedi Academy Performance

Very strong performance until the AA and AF were enabled. Also this test shows that the Nvidia Geforce 6600 GT is perfectly capable of filling the gap the top of line, latest generation graphic cards.

Unreal Tournament 2004 Performance

This demo was very graphic intensive and stressed the cards more then other above games. The number show that the Nvidia Geforce 6600 keeps up with the lower performing current generation cards and out performs in most cases the last generation high end cards.

Final Words

The Geforce 6600 GT give a very high showing in the market. The card keeps up with some of the lower end high end cards (6800 and X800 Pro) at lower resolutions below 1600x1200 without AA and AF enabled. This alone should be enough to sell any normal gamer on the card. Especially that the two previous generation cards (6800 and X800 Pro) go for at least $300 anywhere Anandech could find them, this makes the 6600 GT a much better buy. On top of that, previous generation cards that go for $200 will be much less performing still. This is great for hardcore gamers who just doesn't have $300 to $500 to spend will be very satisfied with a 6600 GT. If they have the $200 in the budget, and PCI Express is a necessity, the Geforce 6600 GT is absolutely the way to go.

Bar Code Label Printers

2009-01-10T20:00:00.001-08:00

Writen by Jimmy Sturo

Bar codes improve data management significantly, and almost every business is using very advanced versions of this technology today. Bar codes speed up data collection considerably by storing significant amounts of data digitally in small black lines that can be easily machine-read. Better printing technology, label materials, scanning systems and wireless communication systems have made bar codes even more indispensable.

Bar code label printers are generally the most common dot matrix, laser, and ink jet and thermal printers. Dot matrix printers are one of the oldest printers used for printing bar codes. In these printers, the lines are built dot-by-dot as a solenoid-driven needle strikes an ink ribbon, transferring the ink to the paper. These printers are inexpensive, can print any form and are easily accessible. However, the quality dot matrix printer is unacceptable today. Ink jet printers are one of the most commonly used printers, especially for high-speed applications. They can also be used to print directly onto a carton where a label has already been affixed.

However, they are suitable for only high-speed printing and may not be very cost-effective for small-scale bar code printing operations. Ink jet clogging, limited barcode resolution, "bleeding" ink, and poor contrasts are some of the disadvantages. Laser printers are quite good as far as the quality of the print is concerned. They have very good resolutions and can scan quite well. However, they cannot effectively print smaller labels. The adhesive on the labels has to be good enough to take the heat and pressure from the printer as most label adhesive tend to melt. Thermal printers for bar coding are of two types: direct printing and thermal transfer.

Bar code printers have to be analyzed on the basis of: quality of the print, readability, initial installation cost, speed, long-term maintenance cost, materials waste. Each of these printers has different results. Thermal label printers score well on all aspects except for material waste. They are most suitable for applications that have variable data fields, point-of application systems, varying label sizes, graphical and scalable text fonts, and high-definition bar codes. They are also compact, quiet, and have lower operating costs.

Today, there are special bar code label printers available with various options like different print modes, label cutter, liner take-up, peel, rewind, tear, real-time clock (for printing time and expiration dates); alerts for maintenance; portability, compatibility with parallel; serial, USB, wired or wireless Ethernet, twinax or coax cables; memory for storing frequently used data; font options like styles and colors; multi-lingual options; sensors and many more. These printers are also compatible with different sizes and materials of labels, including water-resistant, fabric or acrylic.

Prices of bar code label printers start at $300 for a basic printer and may go beyond $3000 for one with all the works. Most of them come with all the required software and tools.

Writen by Richard Romando

Inkjet printers are common equipment both for the house and the office. They are fast, cheap, efficient and produce professional-looking results. Aside from the proprietary inks that you use for these printers, manufacturers also provide you with specialized papers to give you the best quality printouts. Manufacturers claim that original printer papers give you the advantage of sharper text quality and brilliantly colored images, which make office presentations, business proposals and school reports much more impressive.

The most commonly used paper is 28-pound 8½" x 11' matte finished paper. However, you can opt to use higher grained papers. Manufacturers sell these in packs of 200 sheets at around $20 per pack.

If you need larger sized paper, you can also acquire 32-pound 11" x 17" paper with the same matte finish. You can purchase them in packs of 100 sheets at $30.

You can also produce your own brochures or flyers by printing them on paper that has a glossy finish on both sides, giving it a more professional feel. This paper is thicker than the regular types of paper, preventing the ink from showing through to the other side. You can purchase it in 8½" x 11" or 11" x 17" sizes, in packs of 50 sheets, at $13 and $20, respectively.

If you want to print your own photos on your inkjet printer, you can purchase photo paper in 4" x 6", 5" x 7" and 4" x 12" sizes for panoramic photos or 8½" x 11? paper for full-page photo printing. This special photo paper is designed to resist water, smears and smudges. You can purchase 4" x 6" and 8" x 11" photo paper in packs of 100 sheets for $12 and $30, respectively. Panoramic 4" x 12" photo paper is sold in packs of 20 sheets for $15, while the 5" x 7" paper is sold in packs of 60 sheets for $20.

You can also purchase specialized papers like photo cards to print holiday greeting cards, mailing labels, banner papers and iron-on transfers.

The Hard Drive Buyers Guide

2009-01-08T20:00:00.001-08:00

Writen by Steve Jones

As home computers become more advanced, and our uses for them become more complex, the need for higher performance and capacity hard drives increases. It is now possible to choose hard drives with vastly different capacities and rotational speeds, making things more confusing for the consumer.

Thankfully for consumers the hard drive market is extremely competitive and the price at which a high capacity hard drive can be bought is quite astounding. Now that broadband internet is common place, with more and more people downloading music and movies, the need for high specification hard drives has never been greater.

When choosing a new hard drive it is important to consider What you use your computer for. Those who just use their home pc for basic requirements such as word processing and surfing the internet will not need to spend as much on their hard drive as someone who may use music applications or lots of games. When buying a hard drive also try and anticipate any future requirements also.

Lets consider the following hard drive specifications:

1)Capacity

2)Rotational speed

3)Buffer size and transfer rates

In terms of capacity, hard drives can range from 30 - 300 GB. 40 GB hard drives are fairly standard these days. If all you will be using your PC for is to run a few basic software applications and games then this will provide you with plenty of space. But as most people these days are generally also using their home computer to store lots of music, videos and photos, I would strongly recomend buying something between 60 - 120 GB capacity. With hard drives being relatively cheap these days it is better to buy something that will continue to provide storage in the future, than go for a smaller option now and have to upgrade sooner.

The second factor we really need to consider is the rotational speed of the hard drives. This has become a big selling point for manufacturers. The speed is measured in revolutions per minute and you will find figures such as 5400RPM, 7200RPM, 10000RPM, 15000RPM quoted by the hard drive manufacturers. Hard drives work by reading information from rotating magnetic platters as they rotate, hence the faster the rotating speed, the quicker the information is read. There is a down side to faster rotating speeds though, and that is wear and tear. The faster a hard drive spins the quicker it will wear out and it will also be more vulnerable to crashes. Rotational speed is really important, so if your going to be using your PC for music or gaming then you need to buy a 7200RPM drive. If its just for basic usage then a 5400RPM drive will suffice. Again as the price difference between 7200RPM and 540RPM drives is minimal, you may consider opting for the faster speed as this will not need upgrading as soon.

The buffer size and transfer rates will not be of importance to many people, and only need to be considerd by people building dedicated games machines or for high end music applications. The buffer is used as a temporary store for data and the larger the buffer size the better your pc will operate. It is possible to buy hard drives with a buffer size of 8MB. Its best to buy a drive with as large a buffer as you can afford. The same is true for transfer rates, buy the drive with the highest transfer rate that you can afford.

This buyers guide should have covered all the points you need to consider when purchasing your new hard drive, but if you want more information then plenty is avaiable on the internet. For further information please visit our site.

Basic Inkjet Printer Care And Maintenance And Ink Related Troubleshooting

2009-01-07T20:00:00.001-08:00

Writen by Christy Berger

The printer is the one computer component that requires the most attention, though the importance of regular maintenance is often overlooked. Your printer is the single conduit between concept and creation --- the device that brings your virtual media into the physical world.

In this article I will provide tips to maximize your print quality and introduce you to regular maintenance procedures. This information is provided to assist you in consistently producing quality prints and to extend the life of your printer.

Whether you use your ink jet printer frequently or infrequently, to improve and lengthen your printer's life it is essential to ensure that it is clean, running smoothly and is clog free. It is recommended that you clean your printer thoroughly every 6 months for optimal performance based on how often the printer is used. Also, if you have pets it is a good idea to blow the printer with compressed air from time to time as dust and hair take their toll over time.

Keep in mind that the maintenance processes consumes ink, so only perform it when necessary or swap out your ink with inexpensive cleaning cartridges to conserve your ink levels. The maintenance tools can be accessed through the printer driver or control center. Once the cycle begins it is imperative that you run the complete cycle before restarting the printer.

Check the Nozzle: Are you experiencing a faint print quality or are certain colors failing to print? You will need to run your nozzle pattern check utility. If the printout still shows gaps you will need to clean the nozzles.

Clean the Print Heads: If your nozzle check indicates that your print heads are clogged, it will be necessary to run the cleaning utility which removes the blockages. Occasionally it may be necessary to perform the cleaning utility more than once to remove the blockage. Also, some printers have a built in 'deep cleaning' option that you may need to perform.

Align the Print Heads: If the lines and colors are out of sync or there is banding, it may be necessary to align your print heads. This can be done by choosing the 'alignment' option on your printer's utility menu.

If cleaning and aligning do not solve your problem, you will have to contact the original manufacturer to assess the cost of the repair. If your printer isn't covered by a warranty you should weigh the repair cost versus the cost of a new printer. Sometimes a new printer equipped with new cartridges is the most logical alternative.

Testing Capacitorhow To Test A Capacitor When Breakdown Under Load

2009-01-04T20:00:00.001-08:00

Writen by Jestine Yong

Have you ever come across power problem where once you switch on the power supply and the fuse blow? You have checked all the components in the power (primary) and secondary section and all the components seems to be ok! Where is the fault? A fuse blown are usually caused by a shorted bridge rectifier, defective posistor, power transistor or FET, shorted primary winding of switch mode power tranformer, shorted secondary diode and etc. But in this article i'm gone to show you another secret of electronic troubleshooting tips.

I got frustrated as to where is the cause of power problem. Everytime when i switch on the power supply the fuse blow immediately (the fuse became dark color and this indicate that there is a major short circuit in the power supply). I have checked all the components in the power supply and can't find the culprit! What i do is i desoldered all the suspected parts one by one and replaced with a known good component. I eventually found the caused of the power supply problem. Guess what? It was the main filter capacitor (220 microfarad 400 volt). After replacing the filter cap the power supply worked perfectly fine. I begin my detective work to find out why this capacitor can caused the fuse to blow eventhough i already confirmed it ok with my meters.

The meters that i used to check the filter cap were analog meter, digital capacitance meter and esr meter. In this article i will not explain about how to check capacitor or testing capacitor and how capacitor work. I believed most of you know how to check capacitors and also generally using this type of meters. Measured with analog it showed capacitor charging and discharge, with digital capacitor tester it showed around 220 microfarad and with esr meter it showed low esr reading!

This proved that the bad capacitor breakdown when under full operating voltage. Then, how do i confirm that this filter capacitor is faulty? By using an analog insulation tester. When i connect the faulty cap to the meter and press the go button-it showed a very low resistance and this is the proved of short circuit between the plate when voltage applied! There is nothing to do with bad electrolyte. A good capacitor will just showed a charge and discharge in the insulation meter just like you are checking a capacitor using analog multimeter. In the market there is quite a number of ranges that you can buy. It has the range of 50v, 100v, 250v, 500v, 1000v and even 5000v! If you want to test a capacitor of 100 microfarad 160v then you have to select 100v. If you select 250v, it will blow your capacitor that is under test.

If you have the SENCORE TEST EQUIPMENT such as the sencore lc meter LC102 OR LC103, these meters have the capabilities of checking any type of capacitors with four tests:
-testing for capacitor values
-checking for leakage
-equivalent series resistance (ESR) and
-Dielectric absorption

It can check aluminum electrolytic capacitor, film capacitor, ceramic, high voltage capacitor and etc.

Conclusion-Different capacitor manufacturer produced different type of quality of a capacitor. Perhaps the bad capacitor that I encountered are from the lowest grade one. A capacitor failure when under load is very rare. Using ESR capacitor meter alone can solve most of the electrolytic capacitor problem.

Your Cartridge Components Are Clogging Your Inktoner Cartridges And Counterfeits Are Slowly Melting

2009-01-03T20:00:00.001-08:00

Writen by Joseph Mercado

Are you aware of the facilities where your cartridge components are being made?

Some of those parts bought do not always come from the sticker label that is on the cartridge component itself.

There may be times you encounter a marketer who is willing to provide inkjet or toner cartridges to you at an inexpensive price without further concern on the actual component.

This is done in the area of falsehood in which the buyer is deceived by the false markings and doesn't realize the hoax.

Allow me...

The prices from the manufacturer are so cheap it makes the offer irresistable to some and to others it throws up a red flag.

This is what you would call grey market offers that take place in dark dungeoned rooms. A good portion of cartridge manufacturer's turn to the grey market particularly because they need product before the customer's lead time runs out. This can lead into the buyer renegotiating the terms or rejecting the transaction.

The problem with this is when the distributor goes to resell for the manufacturer, the printer toner cartridge componets aren't coming from a reliable manufacturer.

The failure rate for the goods become greater. Some buyers and sellers will catch on to these misguided labels after the defective components have been returned and processed through quality and inspection.

It is nearly impossible to notice the difference in color and quality between a genuine cartridge component and a counterfeit one.

This is why further examination is critical in circumstances such as an investigation. It determines how quick it will fail.

Please let me explain. The last thing you need is an imported quantity of 50,000 inkjet cartridges and find more than 51% of them are duds. This foreign quick scheme is notorious from exporters. You just never know who is replicating these ink items.

Your much better off requesting for a sample and testing it for yourself. Most manufcturers will have you pay for the sample cartridge which is normal. They do this so they are not handing out samples all day otherwise they would be out in the cold with a cup in their hand begging for quarters.

Oh by the way, expect to pay full price for the sample printer ink since it's not a volume order. Counterfeit cartridge labels on cartridge component goods cover approximately 9.7% of the perecent of international and domestic hardware trade.

Recent Studies have indicated nearly $524 billion dollars have been sold throught various trade scandles. Custom duties perform more indepth thorough searches before releasing any goods into the new land. It's a very strict and vitale procedure.

The way this benefits the cartridge counterfeiters is when they don't have to be concerned about marketing and branding purposes, therefore they inherit quite rather large profits as a result.

There are several countries which take place in cartridge counterfeit materials. Be sure to be as sharp as a number 2 pencil in your dealings. Here are 7 regions to have your cartridge sniping scope targeted for the foresight of these incoming counterfeits:

-Nigeria

-Egypt

-China

-Paraguay

-Asia

-Hong Kong

-Philippines

-Vietnam

-Russia

-Ukraine

-And many others

Please don't misunderstand me here, there are suppilers within these regions who are reliable and who do provide authentic product and excellent services. You just have to find them, a matter of who you know at that point. The chances of them finding you is great, so keep your night vision on red alert.

Printer Ink Money Saving Tips

2009-01-02T20:00:00.001-08:00

Writen by Steve Jones

The home printer is a wonderful thing. In a very short space of time we have gone from there being no home printers at all, to most homes having a printer capable of high quality documents, pictures and photographs.

The printing capabilities we now have at home are pretty amazing when you stop and think about it. Even more amazing than this though are the extremely low prices that you can buy a brand new printer at these days. There is however a catch (Isn't there always!).

Printer manufacturers use a very clever marketing model that can be seen in with many other products such as razors and cell phones. They will actually sell you the printer at a loss just so that they can then sell you ink cartridges at over inflated prices. That's why if you buy the manufacturers own ink cartridges you will probably be spending $20-30 for a replacement. They make a huge amount of profit on these ink cartridge replacements, which is why they spend so much time and money trying to convince you to buy their ink cartridges. Well we do not think this is fair, so that is why we are going to tell you how you can beat the big manufacturers and save yourself a lot of money at the same time!

There our a few simple things you should do first in order to make the most of your printer ink cartridges.

Always make sure your printer options are set to draft print until you get the printing your final document.

Always choose black and white print if your printing contains no colors, and have black and white printing set for any of your draft documents until you are ready to print the color version.

Of course the ink will not last for ever even using those two handy hints, so read on and learn how to save money when you have to buy replacement ink cartridges.

Purchase a non-branded compatible inkjet printer cartridge. Many reputable manufactures now make printer ink cartridges, but sell them at much lower prices than if you bought the printer manufacturers own ink. Do not worry about lower quality though as these ink cartridges still meet the same standards.

You can purchase a remanufactured ink cartridge. These will have been used ink cartridges collected by a third party company and then refilled and tested. Again these are cheap and still high quality.

It is now possible to purchase ink refill kits that you can use to refill your own printer cartridges. It is possible to refill one ink cartridge around ten times. It is a fairly easy process to do, the only thing you should try and do is refill before all the ink has been used and the ink cartridge has dried out. With the refill kits being so cheap this can be another great way to save money. As well as being cheap it is also good for the environment because if we recycle our existing ink cartridges less ink cartridges need to be produced and then dumped in landfill sites.

Buy in bulk. You will find deals with many online stores if you purchase several printer ink cartridges at a time.

Hopefully these tips have given you some help. It is best to look online for all your ink cartridge requirements, as prices tend to be cheapest.

Flat Panel Monitors Are They All Created Equal

2009-01-01T20:00:00.001-08:00

Writen by Ellis Pullman

The intuitive answer is no, and yes you'd be right for thinking that. If you see a cheap flat panel monitor for sale, you need to remember that you get what you pay for.

In general the "budget" flat panel displays will lack color balance as well as sharpness compared with the entry-level and higher end flat panel displays. Also one other consideration is whether the machine is refurbished or used. If it's used or refurbished there is probably a higher chance that some of the pixels may be "inactive".

What this translates to is that even if a small fraction of the pixels on your monitor or inactive, there may be parts of your monitors that will stand out more and not be consistent with the rest of the colors on your screen. Sometimes this happens with new monitors too so you need to be careful on this issue.

Though there have been discussions of ways to resolve these broken pixels, such as through special "massage" methods, its clearly preferable to get a monitor that works 100 percent out of the box.

Another thing you might want to consider is the lag time in the video output. For cheaper monitors it may lag a bit more. In general, cathode ray tubes will have the highest available performance in this regard for high end applications.

If possible test out the monitor at the store prior to buying it to see if you notice any glaring shortcomings. Otherwise you may have truly found a good deal.

Things To Look For When Buying A Computer Microphone

2008-12-31T20:00:00.001-08:00

Writen by Mantius Cazaubon

Computer microphones are a valuable addition to any PC and they greatly increase interactivity and communication levels. You can use a microphone for performing various tasks, both business and fun related. For example, you can hold a conference with your business partners, over the Internet, or you can chat with your friends online, instead of doing that on the phone. Of course, in order to enjoy accurate and high quality communication, you have to choose a good PC microphone. There is a huge variety of models on the market, ranging from microphones that you can buy for a few dollars and going all the way to expensive, high tech desktop microphones. So which PC microphone is right for you?

Price Vs Quality

You can pay $5 for a microphone, or you can pay $50. So where's the difference, apart from the price? Well, cheap microphones have low prices for some good reasons: they offer average to low quality sound, they break down more easily and you can't use them successfully in all applications that support a microphone. The materials they are manufactured from have to be cheap, which eliminates the idea of high quality, so the end product is of lower reliability. And at this price, you can be sure bulk manufacturing is present and quality tests are quick and far from rigorous. Microphones that come for a higher price have, in most cases, better sound quality and more features. Such microphones will have noise canceling filters, which help diminish background noise. Distortion filters and integrated circuits also help keep voice sounds clear and accurate. The materials used for more expensive microphones also last longer plastic doesn't crack so easily and if you drop it on the floor you know that the internal components are well protected.

Choosing the right computer microphone

Determining what price range you are in and what model to purchase depends heavily on the purpose you have in mind for the microphone. Are you going to use it just to chat with friends online? In that case, spending a lot of money on a professional computer microphone is not justified. Do you plan to hold business conferences over the Internet? Then maybe you should get a better microphone that will allow the discussion to be continuous and clear, without noise distortion. Giving vocal commands to your computer or dictating to word processing software with speech recognition capabilities is another use for desktop microphones. Quality should be first here speech recognition software is very sensitive and demands a high quality microphone and sound card. Recording your voice and inserting it into music tracks is possible, but a high quality microphone is absolutely essential in this case.

Cd Burner The Day The Music Burns

Writen by Robert Thatcher

Before, owning a copy of your favorite artist would only mean buying either from a local music store or online music sites. And a copy with an average of 16-18 cuts would cost you at least $10. If you think this is reasonable, then consider yourself lucky. However, if you are one of those who cannot afford buying copies of their favorite artists and still would want to listen to them, all you can do is to wait until your local radio stations play their songs. If you have the computer and the Internet connection, you can go to online music sites with free radio like the Launchcast, Shoutcast, Live365, and MSN radio and hope that the song will be played.

Today, with several music download shareware programs it is possible to get your favorite song directly from other users without actually buying from them. These programs let you store the songs you have downloaded to your hard drive or transfer it to your portable MP3 player.

But for you who would like to keep a complete collection of the song by actually storing it to a disc for archiving or play it to your vehicle of home entertainment system, there is one piece of computer peripheral you need: CD burner.

If you know how CD player looks like (and I'm sure you do), you would recognize the CD burner.

CD burner comes into two forms: the "independent" and the "attached". The independent CD burners or writable CD drives do not necessarily have to be permanently attached on the CPU. It could be connected through a USB port with its own power source. The other type of CD burner is the one that is attached to the CPU just like the CD ROM we know for quite some time.

Remember the times cassette players were only meant to play cassette tapes? Then came the cassette recorders that enabled users to copy the content of cassette tapes to a black one.

The same concept applies with the CD burner. It could copy from one CD to another or from a hard drive to a black CD and vice versa.

But to actually use your CD burner, you have to have software. Some of these softwares are available and downloadable for free online. Examples are ISO Recorder, DeepBurner, Burrrn, Windows Media Player, Xduplicator, Cheetah CD Burner, and more. Other CD burner softwares could be purchased. While those for free have the same burning capability, those that are sold give more features and flexibility.

CD burners are not limited to audio copying. It also can copy document files, programs, games, videos, MP3, WMA, and WAV files. Not only that, CD burner with DVD burning capability enables you to copy you favorite DVD collection to another CD if in case you would want to share it to a friend or keep it in case your original DVD is lost. You can also burn a DVD movie after you downloaded it through the Internet so that you could watch it on you television or your home theater.

Although many would argue that the release of the CD burner provides venue to produce uncopywrited CD's whether audio or video, there is no question that CD burner brings the production technology within the reach of the consumers. And soon, as technology still progresses, there would be technology more advanced to cater the needs of music and video collectors and enthusiasts.

Step #1:

Place the cartridge on the work table with the drum facing upward and the small drum gear towards you. Using a small bladed screwdriver, pry off the developer roller drive gear and set it aside.

Step #2:

Rotate the cartridge to the right so the toner hopper is facing you. Using a spring hook or needle nose pliers, gently remove the toner hopper tension springs from the posts at each side.

Step #3:

Grasp the toner hopper with the left hand and the waste hopper side plate with the right. Gently bend the side plate outward, while sliding the toner hopper to the left to expose the right guide post.

Step #4:

The drum cover may be taped back to facilitate handling. Using a small flat bladed screwdriver or needle-nose pliers, take off the retaining clip on the left side of the drum shaft.

Step #5:

Now you will need to hold the large gear end of the drum with your left hand, pull the drum shaft out with your right. Remove the drum and set it aside, just be sure not to lose the washer on the small gear end. If lost, it may take some time finding a new one, so be careful, time is valuable.

Step #6:

Next, remove the two screws holding the wiper blade using a #1 Phillips Screwdriver.

Step #7:

Carefully, slice the sealing tape on the topside of the waste hopper covering the top of the wiper blade (instead, some cartridge uses a foam seal behind the wiper blade, if so, delete this step if necessary). The PCR access door opens inward and sets on the horizontal lip of the wiper blade. Open the PCR door to remove the wiper blade and be careful not to break the two small plastic alignment pins positioning the wiper blade.

Step #8:

Empty out the toner from the waste hopper and inspect the recovery blade for nicks, tears, or wrinkles and replace as necessary.

Step #9:

While holding the waste hopper cavity firmly with your right hand and the wiper blade in your left. Open the PCR door with your left thumb and install the wiper blade on the waste hopper and secure with the Phillips screws.

Step #10:

Now, apply a small amount of padding powder to the wiper blade, drum and recovery blade. Install the drum, washer, drum axle and retaining clip and set the waste hopper aside for now.

Note: If the OEM (original equipment manufacturer) drum comes with a one way spring, it may need to be transferred to the new drum.

Step #11:

Place the toner hopper on your work area (label up) with the developer roller facing you. Using your fingertips of both hands, gently pull off the doctor blade spring and set it aside.

Step #12:

Using a small flat bladed screwdriver pry against the base of the contact plate and remove the contact and lift the end piece from the developer roller.

Step #13:

Grasp the left end shaft of the developer roller and lift it out to the left, doing your best not to damage the Teflon washers or Mylar blades.

Step #14:

Remove the Teflon washers from the developer roller and inspect them thoroughly for damage and wear. Replace the Teflon washers as a set.

Step #15:

Turn the toner hopper to the right so the fill plug is facing you. Using a small flat bladed screwdriver, pry the slotted encoder wheel off and set it aside.

Step #16:

Using the same screwdriver, pry out the toner fill plug carefully and doing your best not to damage it. Clean the filter inside the plug with either vacuum or compressed air.

Step #17:

Empty out all the toner from the toner hopper and clean the hopper with vacuum or compressed air. Be very careful not to damage the foam rollers or Mylar blades.

Step #18:

Using a cotton swab and isopropyl alcohol, clean the developer roller ends, and seal at each end of the foam roller.

Step #19:

Clean the underside of the DR bar with a cotton swab and isopropyl alcohol.

Step #20:

Clean under the ground contacts for the foam roller shaft and the DR bar with a cotton swab and alcohol.

Step #21:

Clean the developer roller with a dry soft lint free cloth or compressed air only. Clean the developer roller shaft with a cotton swab and alcohol.

Step #22:

Install the Teflon washers on each end of the developer roller and slide the flat (keyed) end of the roller into position on the right side of the toner hopper. Lower the left end into position being careful not to damage the Teflon washer on that side.

Step #23:

Install the brass end piece and contact plate into position on the left end developer roller shaft. On the Optra T and SE 3455 rotate the brass end piece downward until the lobe rests between the legs of the contact plate.

Step #24:

Re-install the DR bar leaf spring with the point of the "V" stamped on the spring pointed towards you.

Step #25:

Carefully pour the correct amount of toner into the hopper and re-install the fill plug.

Note: The toner amount must be matched to the correct encoder wheel, key tab and chip to ensure that the customer's machine does not reject the cartridge.

Step #26:

Re-install the plastic encoder wheel.

Step #27:

Place the waste hopper top down on your work area with the opening facing you and the hopper tension springs out of the way. Turn the toner hopper label down and insert the left roller guide into the slot. Lower the right side downwards, while pulling outward on the waste hopper side plate.

Step #28:

Re-insert the guide posts into the proper holes in the waste hopper side plates and reattach the hopper tension springs. Inspect thoroughly for correct toner hopper position and ease of movement.

Step #29:

Re-install the developer roller drive gear. The cartridge is now ready to test.

Step #30a:

At last, align the encoder wheel with the three slots in the down position before packaging.

Step #30b:

Test the cartridge.

Buying Refurbished Electronics Is It Worth The Risk

2008-12-26T20:00:00.001-08:00

Writen by Andrew Ghigo

Introduction

We are always looking for new ways to save on the bigger purchase - irrespective of whether this is a new PC or notebook, a digital camera, or a big screen LCD HDTV for the living-room entertainment area.

Seasonal and clearance sales are always on the agenda of bargain hunters, but there is a further option - that of buying refurnished products. For example, a refurbished LCD TV may sell online for anything from 50% to 80% of its retail price.

Still, even at these big savings, it is not easy to get someone buy a refurbished product for the first time.

To the uninformed, buying a refurbished product may seem like a compromise; it is as if buying a car with dents and scratches on the paintwork, or unknown problems with the mechanics. However, in the electronics world, the tag 'refurbished electronics' does not refer to reconditioned, used or re-build products.

In fact, buying refurbished electronics allows you to enjoy deep discounts and still have a product that is essentially new. What's more, factory refurbished products often come with an extended manufacturer warranty. But...

You need to exercise constant vigilance when buying refurbished electronics. This is only possible if you have a through understanding of what the 'refurbished' tag, once assigned to a product, implies in the electronics world.

What 'refurbished' products are not?

Before we delve further into what may qualify as refurbished electronics, it is important to first understand what cannot be labeled as 'refurbished'. In particular, there is the misconception that 'refurbished' and reconditioned' are one and the same thing. This is NOT.

A refurbished product has practically never been used while a reconditioned is a used product. The difference between a product classified as 'USED' and one labeled as 'RECONDITIONED' is that in the case of a used product, you are buying it 'as is' after it has been used by a first owner. In the case of a reconditioned product, this is also a product that has been used previously - often under lease - but then was repaired (not necessarily by the manufacturer), and resold by a retailer.

Used or re-conditioned products represent greater savings over refurb units as these sell cheaper, but then such products constitute a higher risk. This risk is even more pronounced when dealing with expensive electronic products such as rear projection TVs, home theater projectors, flat-panel HDTV sets and the like. You can never really tell what has been the impact on the aging of the respective electronic components inside the unit as a result of the previous use.

We say: Be wary of such products. Instead, if you are after a smart buy and a great bargain, opt only for 'factory certified' refurbished products. These still represent substantial savings over the normal retail price, and carry a manufacturer's warranty.

So... what qualifies as 'Refurbished Electronics'?

As already stated earlier on, a 'refurbished product' is not a reconditioned product. While the terms 'refurbished' and 'reconditioned' are often interchangeably used say when referring to machines, cars, and the like, yet this is does not apply to the world of electronics. Thus, buying a refurbished LCD TV or plasma television is not like buying a reconditioned TV.

In general, refurbished electronics are items that were returned for one reason or another, to the manufacturer. These items are then re-tested at the factory to make sure they are in tip-top shape. Any defective or damaged parts - if need be - will be replaced in order to restore the product to its original specification, and then the product is repackaged 'like new'.

Refurbished electronics are not used items, but at the same time, these can no longer be sold as new - hence they are sold as 'refurbished electronics' often at deeply discounted prices.

More specifically, reasons for returns include: Customer Return: Most major retailers offer a 30-day money back guarantee; during this period, a customer may return the product for whatever reason and still get full refund. If there is nothing wrong with the product, most stores will simple reduce the price and resell it as an 'open box' special. However, if there is some sort of defect, the product is returned to the manufacturer were it is inspected and/or repaired, and then repackaged for sale as a refurbished item.

Shipping and Exterior Damage: These include damaged packaging due to mishandling, the elements, etc., in which case the product itself may be perfectly fine. These may also include minor damage to the product exterior casing, such as dents, scratches, etc., and any other exterior damage that in it self would not affect the product performance. Retailers would normally return these products to the manufacturer. The manufacturer would then inspect the product, replace any damaged casing, etc., and then repackage the item just like new. However, these items cannot be sold as new; hence they are tagged as refurbished electronics.

Demonstration Units: Sometimes demonstration units at major retail stores, trade shows, and even returned items by product reviewers, are often returned to the manufacturer where they are inspected and/or repaired if needed, and repackaged as refurbished units.

Opened Box: Sometimes, if a box was simply opened, the item is returned to the manufacturer where it is re-tested and repackaged. Even though technically, there is no issue here, yet the item cannot be classified as new; instead, it will have to be sold as refurbished electronics.

Defect During Production: If a specific component is identified as defective once the product leaves the factory - say as a result of an abnormal number of customer returns during the warranty period, a manufacturer may recall a product from a specific batch or production run that exhibits the same defect. When this occurs, the manufacturer can repair all the defective units and send them back out to retailers for sale as refurbished units.

Overstock Items: While most retailers with an overstock of a particular item would simply reduce the price and put the item on sale for clearance, yet there are instances when a manufacturer want to introduce a new model on the market at a time when there are still a substantial number of older models on stores shelves. In these circumstances, the manufacturer may opt to collect any remaining stock of the older model and redistribute them to specific refurb retailers for quick clearance. Overstock items are brand new items; these can be sold either as a 'special promos' for quick clearance, or can be labeled as refurbished electronics and sold at deep discounts.

To strike the best deal, you have to act fast, but not too fast!

Fast... because when it comes to refurbished electronics, you cannot expect to simply walk into a store and pick up your favorite refurbished LCD TV or plasma unit off the shelf. Refurb retailers like RefurbDepot and Second Act, work with manufacturers and distributors to acquire as many products as possible, yet the quantity they acquire can vary from just a few units to a couple of hundred units. In other words, you never really know how long they will last, and at 50% to 80% off the retail price, inventory levels change all the time. Additionally, you never really know if a particular model will be available as refurbished item.

But... do not just jump on the first deal. Act too quick and you may equally miss on the right deal. Act only when you feel you have got the right product at the right price. Once you think you have found what you want, then it is time to check with the retailer about return policies and warranty issues. If the refurbish item is factory-refurbished and comes with a full manufacturer warranty, then it is time to act!

Finally, remember: Purchasing a refurbished item can be a great way to a smart buy. There is no reason why the 'refurbished' tag should lead to a negative connotation to the product under consideration. At the same time, it is important that you inspect the product yourself within the return policy period. This is especially important since with refurbished electronics, you are getting a bit of a hit on product warranty in that you are only getting a typical 90 days warranty against the one year or so associated with standard products.

In other words, it is true that there is a higher risk when purchasing refurbished products, but if you follow through the guidelines detailed in this article, and the additional buying tips detailed in our Buying Refurbished Electronics guide, you can easily transform that risk into a great buy - one which results in a big reduction in price.

And in the end, you are still getting a 'like new' item. Happy bargain hunting!

Inkjet Ink

2008-12-25T20:00:00.001-08:00

Writen by Josh Riverside

The most important part of the inkjet printer is the ink that is used in the cartridge. The quality of printing is directly affected by the quality, type and amount of ink in the cartridge. Inkjet inks are designed for use in specific printers or print heads.

Inkjet inks can be classified into the following categories: water based, solvent-based, oil-based, UV-curing and hybrid ink. Water based inkjet inks have no volatile organic compounds and have low toxicity. This slows down the drying rate in non-absorbent surfaces. They are not suitable for high resolution printing as they tend to feather or bleed. These inks are generally used on paper, while solvent-based inks are usually used for commercial printing like coding and marking on cans and bottles. They dry faster but emit volatile organic compounds. Oil based inks are used for card printing, packaging, labels and boxes where ink is fully absorbed. As the droplets can be formed with very small quantities, they can be used for high-resolution printing. Oil based inks tend to clog if left unused for long period of time but need a special medium to ensure proper drying. UV curing inks are used in high quality printing. These inks do not emit volatile organic compounds, and are thus environment friendly. These are used in applications that require excellent durability such as card printing and billboards. They cure only when exposed to UV light. The cost of UV curing ink is higher than any other ink but requires low print head maintenance. Hybrid inks are a combination of two or more of the above mentioned varieties. Though they are high in cost, they ensure better control of resolution.

Every new development in printing has brought in a suitable modification in the ink used.

Different types of inks are used for different applications depending on various factors like cost, quality and durability.

Convenience More Than Enough Reason To Own A Set Of Wireless Headphones

2008-12-24T20:00:00.001-08:00

Writen by Meryl Rougeaux

Looking for a gift for the business person in your life? Look no further than wireless headphones as the perfect gift...even for the person who has everything. These excellent music accessories make a great gift to give, whether as a business gift or as a personal gift to someone important to you. What makes these listening devices such a good gift? It says that you value their time, safety, and happiness because of what these type of head phones offer.

Professionals can use these for a number of uses. In the office, they allow them to listen to music on their computer, or to take e-learning training or webinars without bothering the people around them and without having cords to get the way of their work.

These same professionals can answer phone calls with wireless headphones and attached microphones, allowing them to converse and participate in conference calls while at the same time doing work that needs to get done (typing, filing, filling out reports, cleaning up their desk, etc.). If the signal sending unit is located close enough, they may even be able to wander around their office while they talk, allowing them to stay engaged in the conversation without getting sleepy or bored by sitting down the entire time. Many units have signal distances of up to 300' away.

While on the road, they allow the professional user to make calls without taking their hands off of the wheel or their eyes off the road. It's a great way to help the busy professional stay in control of the car even during a business call. (However, many people suggest that you should still pull over to the side of the road while taking a call because your mind may not be on the road).

Traveling for business sometimes means working in airplanes, airports, and staying in hotels. Having wireless headphones allow the professional to plug into their laptop and do their work without having to untangle the cords.

Expect to spend $100 or more for a decent set of wireless head phones. You may also want to get batteries for them so the person can use them right away out of the box. There are a number of good brands out there. Some of the top names include: Koss, Logitech, Panasonic, Sennheiser, Iawa, and Shure, bluetooth, AKG, Audio-technica, Etymotic Research, JVC, Skullcandy, Philips, although there are many others.

There are a range of prices and styles. Some of the things you'll want to look for include noise canceling features (to keep out background noise) but those are often (not always), bigger and bulkier than the smaller ones available. One of the best kinds are canalbuds, which fit right into the ear (but don't mix them up with earbuds which are cheaper versions that may be of a slightly lower quality). Canalbuds offer noise dampening and great sound, and are very high quality, but can also be expensive.

Wireless headphones are the ultimate in convenience and safety because of their hands-free use and lack of cords. The professional you're buying a gift for will thank you for making their life far more convenient and enjoyable.

Give yourself the freedom to listen to great music with wireless and cordless headphones from HeadphoneWarehouse.com. This technology really gives you the listening convenience you'll love and use everyday. Get yourself a pair of wireless headphones today!

Uncapping Cable Modems

2008-12-23T20:00:00.001-08:00

Writen by Kevin Stith

Cable modem technology has the ability to achieve speeds in excess of 1 Mbit per second, but modem cables are set to run at a lesser value. It is typically reduced to half of this number for downloads and around an eight of this number for upload. ISPs cap modems to ensure that the bandwidth is equally distributed among users and the upload cap in particular is designed to discouraged users in creating large servers.

Uncapping is defined as the concept of somehow eliminating the bandwidth limit many cable modem service providers impose. Some customers want to do this in order to improve the speed of their cable modem. This is obviously theft of service and may have seriously unpleasant consequences like imprisonment.

One way to do this is to set up a modified DOCSIS config file on a TFTP server hooked to the Ethernet side of the Cable Modem and tricking it to read the config file from the Ethernet side instead of the cable side. There are other ways but it involves highly technical skills in server technology and is too risky.

Cable modems service providers are fighting back with MIC, MAC/IP Checking and DOCSIS 1.1. MIC. Message Integrity Checking is run by authenticating the config file in the modem through robust encryption techniques using a shared secret. MAC/IP Checking is run through the service aggregation device (router) that checks the matching IP addresses with MAC addresses that were assigned to the end user PC during DHCP or statically. This would prevent the IP Accumulation attack way of uncapping. If the BPI+ of DOCSIS 1.1 is enabled, the Fake MAC way of uncapping would be consequently prevented. Most MSOs have not yet upgraded to v1.1, but that is expected to happen over time. Problems with theft of service may influence the decision to upgrade.

Laptop Battery

2008-12-22T20:00:00.001-08:00

Writen by Richard Romando

Laptop batteries are exclusively designed for every laptop model and make. Thus, the batteries required for a particular brand of laptop differ from batteries those that are used for other brands of laptops. The life of a battery depends upon the type of that battery. This means that a nickel metal hydride battery will have a shorter lifespan compared to a lithium ion battery.

Laptops are famous for their phenomenal power consuming capacity. This happens because these batteries must be small and lightweight so that they can be easily fitted in the laptop. A typical laptop battery lasts for about ninety minutes. This is a major problem because laptops are supposed to provide service even on the road or when moving. Using heavier and larger sized batteries can solve this problem.

One more factor that affects the performance of a battery is the temperature inside the laptop. A battery loses half of its power when working because of the temperature in the laptop that can reach the 45°C mark. This happens because of the cell oxidation that takes place inside the battery. Cell oxidation is an irreversible process that is detrimental to the lifespan of a laptop battery.

All these problems cannot be solved in an instant. However, some precautionary measures can be taken in order to save time and money. Leaving a laptop in a car that is parked in the sun will result in battery damage and this situation must be avoided. Using the laptop in a cool room will result in increase in the lifespan of the battery. Lithium ion batteries are well suited for those who switch from a fixed power source to a battery on a regular basis. On the other hand, nickel based batteries are useful for those who prefer using the battery as a primary source for the laptop.

The way in which a person uses a laptop battery and the type of battery used, is more important when we realize there are very few alternatives that can really satisfy a laptop user when it comes to battery failures.

5 Tips For Buying An External Hard Drive

2008-12-20T20:00:00.001-08:00

Writen by Niall Roche

So you've finally decided to buy an external hard drive as a backup option for your computer. This is a great choice for you because you're making backing up your data faster and easier than you could ever have imagined. You're also making your data far more portable in larger quantities than before.

You'll no longer be limited to storing a few hundred megabytes or even several gigabytes. Nope. Now you can look forward to portable and reliable storage capacities ranging into terabytes. That frustrating desktop computer or network file server backup job just got a whole lot easier.

If you've never bought an external hard disk before then there's a few pointers here that may help to have on your shopping list before you go and make that final purchase.

1. Buy A Brand
Do yourself a huge favor and buy a brand name that you easily recognize. Sure these may cost a little more than brand x but with computer accessories like this you really do get what you pay for. If a Western Digital 100GB external drive costs $200 and another brand x 100GB drive costs $80 why do you think that is? Because the company likes you? Because they like making smaller profits? No it's because it's a cheaper drive made with inferior parts that's going to break a lot sooner than you might expect.

The other aspect of sticking with a brand is your warranty. For example Maxtor, Western Digital and Iomega are all reliable companies and well known for their external hard disks. If something goes wrong with your drive you can have it fixed. With brand x you'll probably not even be able to find an email address that you can contact the parent company on. Is saving a few dollars worth that risk?

2. Google It
Whatever brand or model you decide on make sure you do some research before purchasing. Always, always Google the exact brand and model of the drive you're considering buying. Look for reviews and especially any feedback on how reliable a drive is. You'll be very surprised to find that some companies have particularly bad reputations in terms of equipment reliability and what's known as the "click of death" in the external hard drive industry.

Spend time in Google checking out your prospective purchase. You'll be glad that you did.

3. Connectivity
When it comes to external hard drives you'll need to choose carefully when selecting your connection types. Your external hard drive will support either USB or Firewire. Firewire is the fastest option available at the moment but your computer may not support this. The vast majority of modern computers will, however, feature a USB port.

The next question now is what type of USB port do you have - USB 1.0 or 2.0? If your computer only has a USB 1.0 port then your external hard drive is going to transfer data VERY slowly. USB 2.0 is the minimum you should consider as connection options for both your computer and your external hard drive. If you don't have a USB 2.0 port (also called HiSpeed USB) on your computer you may need to get a USB 2.0 card fitted.

4. Speed
Now of course we need to talk about speed. The faster your hard drive operates the faster data will get transferred to your computer and vice versa. Without boggling you with comptuer jargon there's a couple of technical things you need to include on your shopping list.

Seek time - this needs to be 10ms (milliseconds) or less

Buffer size - more is better. Get a drive with at least a 4MB buffer.

RPM - higher is better. 5400rpm as a minimum. 7200rpm being preferred.

Stick to the above basic pointers and you'll do just fine.

5. Size
This is the simple part of the whole "buying an external hard drive" equation. Buy as much as you can afford. If you can afford 100GB then get it. However if you can afford 200GB then get it. Then again if you scraped together a few dollars more you could afford 300GB then do it.

This isn't a sales pitch. Far from it. There is simply no such thing as having too much data storage space. The 160GB drive that I have here was filled up in a little under a month. Currently a terabye option sounds good for my future needs.

Always add 50% to your data storage requirements. Honestly. You'll thanks yourself within the first 90 days of buying your external drive.

Hopefully now you'll be better prepared for purchasing your new external hard drive. It's one of the best purchases you'll ever make.

Standalone Cdrom Copiers

2008-12-19T20:00:00.001-08:00

Writen by Kent Pinkerton

The operational details of stand-alone CD-ROM copiers are similar to those of automatic CD copiers. The only difference between the two is the difference between the CD and the CD-ROM.

CD-ROM means CD-Read Only Memory (ROM). No additional data can be written on these CDs once they are recorded. The recording of CD-ROMs is done by the vendor and is known as stamping. However, the data from these CDs can be written on other blank CDs using a CD-ROM copier, provided the necessary software is available.

CD-ROM copiers work on the technology called "pits and hills." CD-ROMs are coated with an organic layer of dye. When the CD-ROMs are written, the data is encoded on them by burning specific parts of the organic dye coating. These parts are called pits and the remaining parts are called hills. While burning, a laser head reads the pits and hills and then burns the corresponding regions on the blank CDs. This results in the same data getting transferred onto the blank CDs.

The CD-ROM drives are rated with a speed factor relative to music CDs: 1x or 1-speed provides a data transfer rate of 150 kilobytes per second in the most common data format. For example, an 8x CD-ROM data transfer rate would be 1.2 megabytes per second.

CD-ROM copiers may be attached to a computer or they may be stand-alone. Stand-alone CD-ROMs have a hard disc of their own. These CD-ROM copiers are designed in a tower format. Stand-alone CD-ROM copiers may allow several CDs to be burned at once and may contain as many as 2 to 16 unitary drives and can have speeds as high as 52X.

So, if the requirement is to copy a master CD into several CD-ROMs, a high-end stand-alone CD-ROM copier may be the best solution.

Your Business Versus Mother Nature

2008-12-16T20:00:00.001-08:00

Writen by Harald Anderson

Business Consultants earn hundreds of thousands of dollars every year showing businesses how to improve their productivity. All business consultants in the Information Technology area agree that the biggest threat to business survival is data loss.

There are many different data backup solutions available on the Internet today. Unlike years past there are not only different providers but also many different methods of data backup. Some solutions are "on-site" based methods. These include tape drives or other magnetic storage media, DVD-R and CD-R based methods and NAS (network attached storage) methods of creating local (within the LAN) backups of critical data. These methods of data backup are definitely better than nothing, and can provide protection against user error, data corruption, and in some cases even computer theft (that is if the data backup equipment itself isn't also stolen) and many of the other pitfalls associated with digital media.

But what about protection against the most powerful of all forces, Mother Nature?

Hurricanes, tornados, earthquakes, and other natural disasters are a serious potential threat to the crucial data you have stored within your computer network. Add into the equation the collateral damage of flooding and fire that often comes along with Mother Nature's wrath and you have a recipe for some serious data loss in the unfortunate event that one of these uncommon, but critically devastating, events occur. In most cases your existing backup solution would be useless and would suffer the same peril as your original data.

The answer is simple: Have a complete, up-to-date copy of your data stored at a different location. You should back up your data using an offsite data backup service. Offsite data backups allow you to store mission critical digital files in a secure, remote location. When you store data in an offsite location you are doubling the protection of your most import data files and enabling a level of security that even the best on-premises data backup solutions can't provide.

Your data is encrypted and backed up over your existing internet connection to a secure server. You can set it up to perform backups at any frequency you wish. You can even set up the system to schedule backups while the office is empty on weekends and evenings, or when the computers are idle for a certain period of time (great for those systems that need to be accessed 24/7 and cannot afford the potential downtime that may be incurred due to backup procedures being run at the time).

Mother Nature is a concern for the integrity of your critical data. All smart businesses understand this.

Your DATA is your LIFE. Protect it!

Writen by Elizabeth Morgan

Today communication and technology have reached new heights. Various types of electrical devices can be connected to laptops, computers and mobile phones. A special port is installed in these devices from where a USB connector is attached. The other end of the port is connected to external devices such as printers and scanners.

USB is an abbreviation for Universal Serial Bus. USB connectors are used to connect different types of USB cables with all standard compatible USB ports. USB cables are primarily used for data transfer. Data transfer speeds may vary from 12 Mbps in version 1.1 and up to 480 Mbps in version 2.0. USB ports can be also used to connect numerous computer accessories by substituting their particular cables with USB connectors.

USB connectors are available in various configurations. These are widely used to connect two different USB products. They can also be used to connect peripherals to other standard port types. USB connectors provide connectivity to different systems and make possible transfer and translation of data between two separate USB ports.

Among the various types of USB connectors available in the market, the most popular ones are serial to USB connectors, parallel to USB connectors, RJ11 USB connectors and USB Ethernet connectors. Several of these connectors can be mounted directly onto PC boards and are often called USB motherboard connectors or internal USB connectors. However, this variety takes up space and is cumbersome to install.

Panel USB connectors do not need to be mounted upon the PC board. These are attached to the front of the PC board and are also known as USB front panel connectors and front USB connectors. Connectors are designed in definite male-to-male or female-to-female adapters. These may also be made to order as per requirements. Straight and right angle connector types are also available for specific needs.

Learn Hardware And Design Your Commercial Product

2008-12-14T20:00:00.001-08:00

Writen by O G Popa

I am certain the first question in everybody's mind is: "Why should I learn this tiresome hardware design in my spare time? I like to listen music, to play games, and to eat pizza. I just want to relax!"

There is absolutely noting wrong with listening good music and eating pizza in your spare time, but... Living our life is, unfortunately, harder and more demanding with each passing day. If you have a good job today, you also have 75% chances to lose it, tomorrow. This is the new trend in our social life: jobs are not secure anymore. Even worse; if you do manage to "keep" a job for sometime, you could discover, after ten years of dedication and hard-work, you didn't manage to set aside your 100000 $ "safe cash buffer". Realistically, our life today means a permanent search for the next job, a never-ending and terrifying resume work, and also an acute lack of sufficient money for anything.

Our society is polarized into employers and employees; between the two, being an employee it is far tougher! Some time ago a manager was required to know how to work with many, psychically different employees; today, it is the employee who must know how to "deal" with the managers. More often people retire and they have to sell their homes, because they cannot afford continuously increasing costs of living--no, Sir; not anymore. Well, think ahead tiger.

Now, which is the right way to become an employer? If you want--mind this, please: only if you want to--you could start working on becoming an employer today, and hardware design is one (important) way that leads to building your own commercial product and your future business. Besides, it will also increase your chances of employment, so... there are only benefits ahead for you. Please note, our entire social activity it is strongly--if not totally--dependent on hardware, firmware, and software technologies.

The first thing you should know about hardware design is, it doesn't work by itself--well, not much. Hardware it is driven by firmware and/or software most of the times. This complicates things a little, but not too much--don't worry about this. Now, let's detail the action plan, a bit. The first thing you need to do is, start with a reasonable life-plan. For example, you could decide in ten years from now you are going to start your "J J Hardtronics Technologies Ltd." business. Ten years is a good time-buffer, in which you will learn everything you need to know about hardware, firmware, and software design. However, please be aware the most important thing, during these ten years, is to discover your future commercial product!

There are millions of good commercial products waiting to be discovered, and do not look at the high-end technological monsters like cell-phones; this market is so fiercely driven by competition that the best thing is to stay away from it. This doesn't mean you cannot design a good product for the cell-phones industry if you want to. A quick example is a cell-phone utility software program, or a game.

Truth is, the most beneficial applications are the industrial ones. There are thousands of industrial sensors that may be embedded into nice applications; a quick example is the acceleration sensor, or the one that measures the O2 concentration in water. You could design commercial motor-drivers, particularly for brushless DC or steppers motors. Other promising applications are: designing an instructive toy; you could break into the display-signs industry; or you could start building light-organs if you are a true music lover. The analog light-organs were a mandatory accessory in the 60s and 70s; without one, you simply couldn't understand music, because you missed the related visual analog equivalent--please, take this last one just as a personal opinion. (The right way to relate colored light to music is: blue for low frequencies produced by the bass-guitar or drum, then green for solo-guitars and normal organ notes, red for voice, and finally yellow for the highest and most delicate frequencies which few people manage to hear.)

I have seen an automotive coolant sensor controller selling very well for 35 $, and it contained only 2 transistors and few resistors; a temperature transducer was efficiently sold for 20 $ and it contained only resistors! A friend of mine has sold for half a million dollars the license of a tiny, intelligent controller for boilers. Please note, he was a beginner designer, and the application itself was nothing past beginning hardware design level. Of course, my friend was very lucky to find the right people who needed that particular application, and who were willing to pay handsomely for it. This is in fact the difficult problem: finding the right and the needed commercial product, and this is why I said you should allocate ten good years to research the market, or to find the opportunity. Sure, you could discover even ten commercial products in ten years--the more they are, the better it is!

So, the need to become an employer and of improving your skills are sufficiently strong motivations to start learning hardware design. You could still be unclear about why hardware design in particular; why not firmware, or even software design? This is true, and you could do it anyway you want; however, starting with hardware design it is particularly beneficial. First of all, hardware is the beginning of the hardware-firmware-software chain, and it is best to start everything from the very beginning, one step at a time. Secondly, hardware design helps building your commercial product as an independent unit, or as a perfectly contained application. Next, the range of beneficial hardware applications it is way larger, and the competition is a bit less brutal, when compared to firmware and software. On the other hand, hardware design is going to lead you, naturally, to firmware and software design. My belief is, starting with hardware design it is the best method of learning, because you take everything from ground up.

All right, I am certain you are motivated enough by now. Your next question is: "How do I do this?" You see, this is in fact the easy part! Incidentally, you could start by visiting my home site, Corollary Theorems. Have no fears, my friend; you are going to discover that hardware, firmware and software design are very easy to learn, and they are even fun!

Little relaxation in your spare time it is very good and quite necessary. Although you do not hear much about this, lately, when I was a bit younger we were encouraged to experiment with "active relaxation". This means, by reading an instructive, useful book, you could get the same level of relaxation as when listening music, or playing PC games. However, the lecture of a good book is going to enrich your level of knowledge, and you will gain valuable skills, instead of just "killing time". This is the theory behind the active relaxation concept. Nice, aye?

Everything You Need To Know About Touch Typing

2008-12-13T20:00:00.001-08:00

Writen by Sindy Coffard

Hunt - and - peck typing vs. touch - typing

Typing is an immanent part of work for predominant number of people. It is a daily task, the ability we can't go without. It is no wonder that the necessity to master this skill has increased essentially in the recent years. It led to the emergence of the considerable amount of computer courses, which were flooded with those who eagerly wished to master typing as quickly as possible. Meanwhile, the popularity of courses was brought down by various computer self-tutors, which offered amazingly fast programs to master typing.

It was natural that the typing skills were tried to be improved. People aimed at equalizing quality and quantity. Hence, the method which combined all the requirements to typing with personal approach to each user was invented and called touch-typing. Touch typing means to engage in typing without having a look at the keyboard. The fingers are trained to locate the keys by position.

It is an intrinsic to the human beings to bring the development of the skills to perfection, to introduce automation to the daily routine, to simplify life by all means, making it more enjoyable. Same was in the case of touch - typing.

Touch-typing has become an essential, even mandatory skill these days no matter what line of work anyone does. Touch-typing is a method of typing, where the typist uses the sense of touch finding the proper keys rather than the sight. This method of typing is considered to be highly effective, as it redoubles the productivity of work and allows the typist to concentrate not on the search of proper keys while typing but on the sense of the information he types. In such a way the typist avoids the process of continuous and time consuming proof reading and makes only some minor editing after typing. The quantity of the misprints reduces twice.

It was counted that using the touch - typing method allows touching 60+ words per minute. People using the touch - typing method have much more advantages in comparison with the 'hunt - and - peck' typists. Hunt - and - peck typing or so called two - fingered typing is slower than touch - typing, using this method the typist required to find each key by sight, instead of relying on the memorized position of the keys.

It takes from 30 to 40 minutes to type one page of the text by the 'hunt - and - peck' method and only 5 or even 4 minutes by the touch typing method. So it helps to blueprint the time more rationally. At the same time general culture of labor increases. There is an important rule of touch typing which makes the technique of this method easier and distinguishes it form the 'hunt-and-peck' method. The less quantity of keys falls at one finger, the quicker the typing is.

Mastering the touch - typing and utilizing it in practice also helps to preserve health. As touch typists don't have to shift the gaze from the keyboard to the screen, so the eyes don't get tired and the eyesight doesn't damage. Consequently, touch - typists are able to cope with the larger scopes of work and get tired less after the working day. At last, touch - typing leaves more time for the personal life and lets you enjoy your work.

Touch - typing software

How is it possible to master and become familiar with touch typing? There are a great variety of programs, which were specially elaborated to teach touch - typing. Preparing this article I've got acquainted with a stunning number of the freeware and read a lot of polar comments about different programs which teach touch typing. I want to share with you the information about some programs which are considered to be the most effective in teaching touch typing. They received a lot positive feedback both from the users and from the specialists.

Stamina Typing Tutor 2.5 is a multifunctional typing tutor with support for several layouts: QWERTY (US, UK), AZERTY, Dvorak etc. The intimate details: work with lessons and text (5 modes), a lesson editor, statistics, progress graphs, virtual keyboard (can be hidden), super MP3 sounds and music, a play list, support for several users.

Kiran's typing tutor is an effective typing program, which was worked out especially for beginners. It contains 500 typing lessons and 500 testing lessons. It measures typing speed, errors for each letter and shows Accuracy, Word per minute and key per minute after every lesson.

TypingMaster Typing Test is a full-featured typing tester for Windows. After warming up with enjoyable typing games, you can evaluate your typing skills with any of the several test texts, or add your own one. This program includes custom texts, multi-user support, warm-up games, result history, and a printed test diploma.

Max Type LITE is a multifunctional typing tester for Windows, which has two different modes of learning. Extreme Typing mode allows you to compete with an opponent, who can be set according to your typing level, for a typing speed in a chosen text. Another unique feature of this mode is that the record of your own typing at a wanted replay speed can be your opponent. Typing Test mode gives a possibility of statistical evaluation of your typing according to 20 parameters of any txt-file.

KP Typing Tutor is an easy-to-use program, which lets you practice basic typing course, sentences and longer texts. KP Typing Tutor supports Dvorak keyboard layouts (Dvorak, Left Single-handed Dvorak and Right Single-handed Dvorak) with special typing courses.

And one more program, unique to my mind. Only imagine it can teach you to touch type in 90 minutes! KAZ - Learn To Touch Type in 90mins v17 costs 13.97 $ on the Amazon.com. It is based on just 11 words in 5 phrases. It offers KAZ Speed builder short practice sessions for daily use. KAZ - Learn To Touch Type in 90mins v17 is designed for all ages from 5 to 95 and can be utilized in all versions of Windows to XP and Mac OS 8, 9 and X on same CD ROM".

Touch - typing technique

How does touch typing method work? Everything is simpler than can seem. The keyboard is divided in the areas; moreover each area corresponds to the appropriate quantity of fingers, for instance keys QAZWSX should be typed with a little finger. The position of the hands also depends on the areas; your left hand's fingers should be placed on the home row keys ASDF and your right hands' fingers should be on the keys JKL;. The letters on the keyboard are positioned so that the most frequently used letters are placed in the central row and are pressed with the forefingers.

By the way, there are a lot of different variants of layouts. The type of the layout is also important in the development of the technique of typing. The most habitual and accustomed is QWERTY, moreover it is the most frequently used layout, but according to the results of testing Dvorak proved to be more effective as it increased the speed of typing for 20 - 40 percents.

In touch typing not only the correct position of the hands and the type of the layout are significant, but the position of the body also plays an essential role. Your posture should be straight, legs shouldn't be crossed, palms and fingers should be loose as though they rest over the keyboard. Imagine that you are having an apple in your hand and it is going to slip. You should hit the keys lightly and abruptly. The quieter the sound from the keyboard is, the better it is. Touch the keys with the finger cushions and after the hit withdraw the finger from the key.

Hence, I recommend you not to procrastinate and to set to touch typing right now. Remember "Knowing how to study is like knowing how to fish. It is a set of learning skills that lasts a lifetime and brings many rewards. Just as there are ways to know that you are a competent fisherman, there are ways to develop skills competency." And one of them is touch typing.

5 Ways To Backup Your Data

2008-12-12T20:00:00.001-08:00

Writen by Jason Kohrs

The data on your hard drive is the most critical item inside your computer, and the only item which can not be replaced. It may be an unwanted hassle and expense to replace a defective memory module, monitor, or processor, but there is no replacing data once lost.

In addition to the possibility of a simple hard drive failure, the threat of internet borne worms and viruses has become an increasing risk to data loss or corruption. Although you may not be able to provide absolute protection to your hard drive, there are various ways that you can ensure that the data on your hard drive is protected. Five methods of backing up your data are summarized below

1. USB Flash Drives

Although I am not recommending that flash drives be used for the actual data storage, they are a convenient means of transferring data from one computer to another. Important files can be quickly loaded onto a device such as the MINIDISK-512-DGRY-CS USB 2.0 Flash Drive, and transported to another computer for safe keeping. Installation and operation is extremely simple, and other than perhaps having to install a software driver, the use of a USB flash drive is a matter of having an available USB port on your computer. Just about every computer produced over the last several years has USB ports included, with more modern systems supporting the USB 2.0 standard. USB 2.0 allows for data transfer rates of up to 480 MB/s, which is a tremendous improvement over the original USB speed limit of 12 MB/s, and allows a user to fill their drives with data in a relatively short period of time.

Although the storage capacity of flash drives has increased greatly over the last year or so, users are still limited to common sizes of 512MB and 1GB. Mass storage is obviously not an option, but even 512MB may be enough to backup your "My Documents" folder, several albums of MP3s, or other important files to be stored elsewhere.

2. CD and DVD Writers/Re-Writers

The falling prices of CD and DVD writers/re-writers have made them a staple of just about every modern computer. These devices can typically be found installed in a computer case, but external devices supporting USB 2.0 or Firewire are available for greater flexibility and ease of installation.

A combination drive, such as the NU Technology DBW-521, will provide the user a high speed CD reader/writer, as well as a DVD reader, for under $40. The extremely low price of the drive (and the blank media) makes for an inexpensive means of creating data backups, and the re-writable media increases the convenience by allowing the same disc to be erased and reused many times. The main limitation of using a CD writer for data backups is that the discs are generally limited to a capacity of 700MB per disc. Not nearly enough for a full backup, but adequate for archiving key files.

The popularity of DVD writers/re-writers has surged thanks to dropping prices, and they are pushing the stand alone CD burner towards extinction. DVD media affords the user far more storage capacity than a CD, and DVD burners can generally burn CDs as wells as DVDs. The recent availability of double layer DVD burners, such as the Sony DW-D22A-DO-N, represents a large boost in the capacity of writable DVDs, taking the previous limit of 4.7GB per disc and nearly doubling it to 8.5GB.

With proper storage, CD/DVD media can provide long term storage that can not be jeopardized by hardware failure. The data on a CD or DVD can easily be read by just about any computer, making it a good choice for archiving files that aren't excessively large.

3. External Hard Drives

As the name might imply, external hard drives are generally the same type of drive you might find inside your system, but housed in a smaller, external enclosure of its own. The enclosure will feature at least one data interface (such as Firewire, USB, or Ethernet), and the capacity is only limited by the size of hard drives presently available and the user's budget.

The Ximeta NetDisk is an example of an external hard drive that provides a user the option of connecting an additional 80GB, 120GB, or 160GB of storage to their system by using either a USB 2.0 or Ethernet connection. Installation for such a device is rather simple, and may involve the installation of some basic software, as well as making the necessary connections between the computer and the external enclosure.

The capacity of external hard drives makes them ideal for backing up large volumes of data, and many of these devices simplify the process by including software (or hardware) features to automate the backup.

For example, some Seagate External drives feature a "one-button" backup option right on the case.In addition to being a convenient method of backing up large volumes of files locally, most external hard drives are compact enough to be portable. The inclusion of a common data transfer interface, such as USB, allows an external hard drive to be connected to just about any modern computer for data transfer, or for more than one computer to share the external hard drive as a back up.

4. Additional Hard Drives

By simply adding an additional hard drive to you system, you can protect yourself from data loss by copying it from your primary drive to your secondary drive. The installation of a second hard drive isn't difficult, but does require a basic understanding of the inner working of a computer, which may scare off some users. We do offer a "how-to" section on our site for many tasks such as installing a hard drive into a computer system.

To take the installation of a second hard drive to another level of security and reliability, the hard drives may be installed in a RAID array. RAID stands for a Redundant Array of Independent (or Inexpensive) Disks, and can be configured in several manners. A thorough discussion of RAID and all of its variations would be an article all by itself, but what may be of interest to this discussion is what is known as RAID 1. A RAID 1 array requires two hard drives of equal size to be installed on a RAID controller, which will then mirror one drive to the other in real time. Many motherboards now come with RAID controllers onboard, but the addition of a PCI slot controller card, such as the Silicon Image Sil0680, is an inexpensive purchase that will add RAID to any system. With a RAID 1 array in place, if one hard drive should ever fail, the system won't miss a best by continuing to run on the remaining good drive, and alert the user that one drive may need to be replaced.

5. Online Storage

Online services, such as Xdrive, allow users to upload their files to a server for safe keeping. Although it may be convenient to have the data available wherever an internet connection is available, there are a few limitations.

The services generally charge a monthly fee relative to the amount of storage space required. At Xdrive, for example, 5GB of storage costs $9.95 per month, which can quickly add up to more than one would spend on any of the other options discussed.

Security is supposed to be very tight on these services, but no matter how secure it may seem, it is still just a password keeping prying eyes from your potentially sensitive documents.

The speed of your internet connection will also weigh heavily on the convenience of your backup, and no matter what type of connection you have; it can't compete with local data transfer rates.

Final Words

Although not a comprehensive list of options available for backing up your data, the five items listed provide some simple and relatively affordable means to ensure that your data is not lost. Data loss is an extremely frustrating and potentially costly situation, but one that can be avoided.

Blade Servers Offer Efficient Energy Usage And A Lower Tco

2008-12-11T20:00:00.001-08:00

Writen by Mike Colesante

With the release of dual-core Xeon chips for blade servers, Intel has again accentuated the ability of companies to save money in terms of lower power consumption and increased reliability.

Studies indicate a blade server can reduce power and cooling costs 15 to 25 percent, meeting the needs of energy-conscious customers. The dual-core/dual-processor capabilities are ideal for a wide range of low-power communications and embedded applications.

Blade-server fact: Even blades that don't use lower-power processors can reduce the overall power and cooling requirements of a rack by eliminating many duplicate power-consuming infrastructure components that are included in 1U and 2U rack servers.

A blade server might only consume one-half or two-thirds the power of traditional 1U and 2U rack-mount servers of equivalent processing power. The reason is that the consolidation of the resources helps the blade server gain an economy of scale. For example, rather than having 10 500-watt supplies for 10 traditional 1U servers, a blade server can have two 2,000-watt supplies.

With all that support gear removed and put into the shared chassis, the blade server is much smaller. With the reduced size, the blade server can be hot-plugged into the chassis, which provides the power and cooling. Therefore, the shared chassis provides a much more efficient use of space and power.

Add new, low power processors to the efficiency of a single chassis and blade servers become an increasingly attractive option for server consolidation projects.

The three new Xeon server chips released this year by Intel are Sossaman (released March 14), Dempsey (May 23) and Woodcrest (June 26).

The Xeon chips combine the benefits of two distinct high-performance execution cores with intelligent power management features to deliver significantly greater performance-per-watt over previous single-core Intel Xeon processor-based platforms. The following is a brief explanation of each:

Sossaman (also known as the Xeon Low Voltage) uses approximately 30 watts of power and is rated at 31 watts Thermal Design Power (TDP). It packs two to four times greater performance-per-watt than its predecessor, a 55-watt version of a single-core Intel Xeon chip called "Irwindale."

The processor comes in 1.66GHz and 2.0GHz speeds and offers 32-bit instead of 64-bit addressing (because it is derived from a notebook chip). It has a front-side bus speed of 667 MHz and L2 cache size of 2 MiB.

Within almost a month of each other, Dempsey (Dual-Core Xeon 5000 series) and Woodcrest (Dual-Core Xeon 5100) were released by Intel. The release of Woodcrest made some believe Dempsey, based on the Intel "Bensley" server platform, was immediately obsolete. However, Intel has marketed Dempsey as a low-cost alternative to Woodcrest.

The most important comparison of Woodcrest with Dempsey is that Woodcrest consumes far less power and dissipates much less heat than Dempsey because the micro-architecture was heavily optimized to reduce power consumption. Woodcrest comes in three varieties, the 40W TDP versions optimized for blades, the mainstream 65W TDP parts, and the 3GHz top bin part which has an 80W TDP.

All parts below 3GHz will fall into the 65W or 40W TDP range. In comparison, the top bin Dempsey parts had a 130W TDP, and mid range parts were rated at 95W, and the massive power requirements and thermal issues precluded ever using Dempsey in a blade.

Moreover, Woodcrest also has improved sleep states and clock gating which help to lower average power.

Dempsey's speed ranges between 2.67 and 3.73 GHz. Some models have an FSB speed of 667 MHz while others have an FSB of 1066 MHz.

Woodcrest, the first Intel core micro-architecture to be launched, provides an 80 percent boost in performance, while reducing power consumption 20 percent relative to Pentium D.

It has an FSB of 1333 MHz in most models, except for the 5110 and 5120, which have an FSB of 1066 MHz, with the fastest processor clocking in at 3.0 GHz. All Woodcrests use LGA 771 and all but the 5160 and 5148LV have a TDP of 65 W, which is much less than the previous generation of 130 W. The 5160 has a TDP of 80 W, still much less than 130 W.

Intel has begun shipping to its customers the next generation of Intel Server Systems, Server Boards and Server Chassis featuring the Dual-Core Xeon 5000 and 5100 sequences (Dempsey and Woodcrest).

The use of these blade servers provides great benefits to small and large businesses alike. For smaller operations, one or several individual servers are often the most cost-effective way to support a small network. In larger installations, particularly ones that are expected to grow quickly in capacity, the blade server architecture offers more impact and easy expandability.

In summary, blade servers - with the latest releases of Intel dual-core Xeon chips - increase reliability, decrease energy consumption, and are the best logical choice for a company to save money and improve manageability.

Touch Screens

2008-12-10T20:00:00.001-08:00

Writen by Kent Pinkerton

Wikipedia defines a touch screen as a display overlay. A touch screen is fundamentally an input device like a mouse only with touch screens, your finger on the display screen does all the functions a mouse pointer does. By simply touching the display screen, users can perform various functions.

Interestingly, a touch screen can be used for most computer applications. If you have a touch screen display for your home computer, you will probably never need a mouse again. The technology is somewhat comparable to that used in touch pads in laptops and other computing systems. Currently, touch screens are more popular for commercial uses like touch screen kiosks and at customer support desks.

There are various kinds of touch screens. Podium touch screens, touch panels, touch kiosks and touch screen monitors are some of the many varieties of display overlays that use the touch screen technology. The technology behind touch screens is complex. These touch sensitive displays use resistive, capacitive, photosensitive, or acoustically sensitive technology. Touch-sensation is the basis of resistive technology whereas capacitive technology works through electrical sensitivity. On the other hand, photosensitive touch screens operate through infrared rays and acoustic touch screens operate on the principles or surface acoustic wave.

Touch screens are very popular in the retail environment. Here, they are useful for providing information to customers. Touch screens are attractive and customers can use them without much technical knowledge. If the touch screen is used on point of sales, the screen usually also has a stylus that can be used to enter data into the system. This is common at ATMs where you can enter account information through a stylus.

Touch screens are getting very popular as a friendlier input device. Even gaming systems and smart-phones use touch screens. The technology is quite advanced but touch screens are more expensive than regular display systems so their usage is currently limited to the commercial segment only.

Save Money By Buying Bulk Computer Printer Ink

2008-12-09T20:00:00.001-08:00

Writen by Frank Bolsom

When it's time to replace you printer ink cartridge, buying bulk ink will save you some money. You need to be sure the bulk ink will be suitable for your printer, however. So how do you find the best deals?

The following your alternatives:

Original Manufacturer Cartridges

You can usually buy them for less if you buy them in bulk. If your printer uses both a black cartridges and a color, you likely use more of one than the other. If you're going to buy them in bulk, just buy the one you use most.

The original manufacturer's cartridges will usually give you the best quality prints out of any of the alternatives. They are the most expensive, however.

Also, if you buy them in bulk keep in mind that they do dry out. Most ink cartridges have a "best before" date on the box. If they sit too long before you use them, the ink may dry out (which means your bulk purchase savings will disappear out the window).

Remanufactured (Refilled) Cartridges

There are many companies that sell remanufactured cartridges. These are basically refilled OEM cartridges, but without the hassle and mess of doing the refilling yourself.

The companies that refill them also usually do a more thorough job of cleaning and testing them than you can do yourself, so they tend to be more reliable.

These cartridges are much like the original brand of ink - they will dry out if they sit too long. Don't buy more than you need to last you for a couple of months, otherwise they may not work by the time you use them.

Do-It-Yourself Refill Kits

These kits let you refill your empty cartridges and are the cheapest option of them all. The bottles that hold the ink until you refill the cartridge are also much less prone to drying out, so these kits have a much longer shelf life.

The refilling process can be tricky, however, for some printer models more than others. It can be quite messy if you aren't careful.

Comparing the Costs

Let's compare the price of each of the above options:

An original HP ink cartridge for the V40 series printer costs about $30 from most stores (black only).

If you buy this ink in bulk from a wholesaler, it will cost about $100 for 4 cartridges, or $25 per unit.

You can buy remanufactured ink cartridges for the same printer for $21 each, or less if bought in bulk.

Finally, a bottle of black refill ink for that printer will cost you roughly $15, and will refill the ink 4 times. This works out to $3.75 per refill.

If you are shopping for a new computer, you usually look at the size of the hard disk first, but you should also know what monitor you are purchasing. The monitor displays the messages and data that are processed and utilized as the CPU (central processing units) speed or hard disk size.

There are two kinds of monitor technologies available on the market the CRT (cathode-ray tubes) monitors and LCD (liquid crystal display) monitors. CRTs are bigger and bulkier than the LCD, and they consume a lot more power. The screen also tends to flicker. The LCD monitors are more expensive than the CRT and have less color replication. However, LCD technology has advanced, and its viewing quality is comparable to CRT. Most people still choose the CRT monitor.

For many years, the CRT monitors were the only choice consumers had for monitor technology. CRT technology is used in most televisions and computer monitors. It works by moving an electron beam back and forth across the back of the screen. Each time the beam passes across the screen, it lights up phosphor dots on the inside of the glass tube. and it illuminates the active portions of the screen. By drawing many such lines from the top to the bottom of the screen, it creates an entire screen of images.

LCD technology is used in digital watches and computer monitors. This display has two sheets of polarizing material with a liquid crystal solution between them. An electric current passed through the liquid causes the crystals to align, and light cannot pass through them. Each crystal, is like a shutter, either allowing light to pass through or blocking it. To produce color, LCD displays use two basic techniques: Passive matrix and thin film transistor (TFT). Passive matrix is the less expensive of the two. TFT, or active-matrix, produces sharp color images like the CRT, but is much more expensive.

How To Choose Laser Printers Inkjet Printers Dot Matrix Printers

2008-12-07T20:00:00.001-08:00

Writen by David Arnold Livingston

Man is always in constant search for knowledge which he makes use to create innovations that will make his life better. Among the varied inventions of man is a computer printer. The first computer printer can be traced back in the year 1953 which was developed by Remington-Rand as a match for Univac computer. Laser printers were evolved from the dry printing process or Xerox invented by Chester Carlson in 1938. 1971 witnessed the birth of the first laser printer which was then named as EARS. The next years are period of experiments and added inventions which paved the way to the first IBM printer. The IBM 3800 Printing System was considered as the first high-speed laser printer with a speed of more than 100 impressions-per-minute.

Nowadays, a computer printer is of vital importance in the different areas of human activities. It goes hand in hand with a computer as a component that generates the hard copy or a readable text from the stored data on the computer's system. Several printer technologies are available today but it can be categorized into two types - namely the impact and the non-impact technologies. A computer printer that uses the impact technology is equipped with a system that requires contact with the paper or whatever material that can be used to produce the readable text.

Dot Matrix and Character Printers are the two major classifications of Impact printer technology. A character printer is a computerized typewriter made up of a group of bars which serve as the platform for letters and numbers. Like a typewriter, the right characters are hit or struck to touch the ink ribbons which in turn pass on the characters to the paper. It can be used with speed but has limited uses. Computer printers with Dot matrix technology have a group of small pins needed to strike the ink coated ribbon to pass on the image to the paper.

A printer using the Non-Impact technology does not need contact with the paper to produce the desired image. An example of this is the commonly used Inkjet painters and Laser printers. An inkjet printer directly sprays drop of inks into the paper while a laser printer is equipped with a toner, heat and static electricity to produce the image. Inkjet printers are used in almost all offices, business, café and many other establishments. The printed image coming from an inkjet printer has tiny dots that usually have a diameter of 50-60 microns.

Print head assembly, paper feed assembly, power supply, control circuitry and interface ports are the parts making up a typical inkjet printer. The quality of the produced image in an inkjet printer is also dependent on the type of paper used. Brightness and absorption are the main factors that determine the quality of the printed image. The brightness is determined by the smoothness of the paper's surface. Smooth surface reflect more light which makes the image brighter. Absorption refers to the ability of the paper to take in the ink. Papers with good absorption capacity have images that will stay tight while poor absorption capacity can result in blotting.

Monochromatic and multi-colored images can be produced depending on the type of printer. Monochrome printer is only capable of generating images with only one color, commonly black, while a color printer can produce colored images. A printer can transform a group of characters, a vector image and a bitmapped image into a printed version. Other printers however cannot process all of these types. By examining your needs, you can choose the optimum printer for you.

Keep Your Work Mobile And Make Your Life Easier With A Laptop

2008-12-06T20:00:00.001-08:00

Writen by Gregg Hall

My Acer laptop computer has changed my life. In fact, I can say quite honestly that it has revolutionalized the way that I work. It has made me much more productive and efficient overall. How, you might ask? As a writer, I need to remove myself from the distractions at home. And I would much prefer to work in the quiet, soothing atmosphere of a coffee shop. But doing so in the past meant recording everything with pen and paper and then retyping it upon my return home. What a waste of time. But now, my life has changed.

Owning my Acer meant not only that I could leave my home and work from the coffee shop, but I could leave town and still work. If I needed to travel for business, I had my work right there with me, on the plane, in the airport, in my motel. The Acer even affected my social life. Instead of finding myself bogged down, I can just type up my reports and head out the door to meet my friends for a night on the town. I don't even have to stop at home. I can just pack my laptop up, slip it in the car, and then enjoy the rest of the evening with friends. Work and play have become one.

To make my Acer more productive and efficient, I had to modify its operating system. Instead of relying on the old standby of Windows, I converted the operating system to red hat linux. Linux offered a faster and more stable system than windows, which has recently made computers more vulnerable to viruses than linux. In a nutshell, windows can kill your system. It slows it down and opens the door up for a plethora of viruses.

I also learned that to rely on my laptop, I needed to maintain it and protect it. Laptops are much more vulnerable to damage than a desktop, simply because we carry them everywhere we go. How often do you lug a computer tower around? Thus I recommend investing in a hard case. Sure, soft cases are cheaper and easier to carry, but in the end, you will want a hard case to protect this high dollar investment that you just saved a couple months worth of paychecks for.

Because of their vulnerability to damage, laptops should also be backed up frequently, daily if possible. No one wants to lose valuable information, so back up your information on a flash drive or CD. Consider using your desktop as a backup as well for the information on your laptop.

My Acer has saved me days of work. I find myself enjoying my job even more now that I am not chained to the same desk in the same room for hours. And I find myself enjoying life more when I know that I can just pick up and go in a moment's notice.

My Pc Is Slow What Should I Do

2008-12-05T20:00:00.001-08:00

Writen by Damien Oh

No matter how good your system is, there'll sure be a time when you face the slow pc performance syndrome. This is a universal problem every user sure to bounce into.

So when do you consider your PC slow? When you discover that the booting up time is more than the usual loading time, there is frequent hanging of PC, taking load of time to start an application or sluggish game play.

What is the cause for this? Well, it can be due to the hardware or software issue.

A lack of memory RAM is often the main cause for hardware issue. As technology advances, more and more software with heavy bandwidth are being developed. An old system with only 64MB of memory RAM will surely pants when running these heavy duty programs. Check out your motherboard maximum memory support and upgrade the RAM to the maximum. This will see an improvement. If your memory RAM is already at its maximum, then maybe it is time to change the motherboard.

Other than the RAM, the CPU is also another culprit for the slow performance. Similar to the RAM, an old CPU will not be sufficient to support new and complex applications. It might be easy to think that changing the CPU will help; however, changing CPU is not as easy as changing ram. Most of the time, the old motherboard will not be able to support the latest CPU in the market. If you are seriously considering changing the CPU, then it might be better to upgrade the whole system.

The data storage on the hard drive is based on sector allocation. Over the time, due to frequent installation and un-installation of programs, the data sectors will be scattered all around in the hard drive, making data retrieval difficult. This in turn adds up to the loading time. The hard drive fragmentation percentage refers to the percentage of the scattering of the data sector. The higher the percentage, the slower the performance. Performance can be improved by doing a defragmentation. This will arrange the sector cluster in retrieving order and also move seldom used or unused data to a remote sector.

Running of background processes and programs will also slow down the pc performance. Most of the time, these background activities occur without your knowledge and it is always the main cause for PC hanging. To eliminate this, press Control + Alternate + Delete to access the Window Task Manager. Click on the PROCESSES tab. This window will slow all the background processes. Select the application that you don't need and click 'End Process'. Do this with care as shutting down of important application will cause your PC to hang and all your unsaved data to be lost. Next, the right bottom panel of the window task bar shows the program running in the background. Right click on the icon and shut down the unused programs to free up the bandwidth.

With these few tips, it will be sufficient to improve your PC performance. If the above technique don't works, then you might have to consider reformatting your pc or upgrade to a new system.

Video Cards And Related Technologies

2008-12-02T20:00:00.001-08:00

Writen by Logan Rokwild

How does a video card work?

A video card basically converts the computer's digital signals coming from the processor into a signal that the monitor is able to interpret. Hence, its basic function is to convert data. The main point of difference between an entry level video card and a state-of-the art one is that the latter's conversion speed is much better.

The Chips

The chip is the heart of the video card. It is where all the processing is done. It also makes 3D acceleration possible. The chip is to the video card, what the processor is to the computer. Of the two major chip manufacturers, ATI and NVIDIA, the former is well known for high quality and great technology.

Pipes

The information must travel through tunnels called 'pipes', before it can be converted. On one end it starts as raw data and ends up at the opposite end in a format that is compatible with the monitor. On its way, the data undergoes the conversion process. The greater the number of pipes, the more data that can be converted simultaneously.

The amount of data that a pipe can hold is called its Memory Interface. A pipe with a 128 bit interface can process more data than one with a 64 bit interface.

Memory

The memory is used to store temporary or transient information. Video information, being very data heavy, needs more memory. The two main types of memory are SDRAM and DDR RAM. DDR is superior as it can transmit information faster.

ATI Technology

An ATI card will offer many technologies that will significantly enhance your video experience. ATI's cards are fully compatible with all the latest 3D technologies and do not rely on your computer's CPU to process information, as do some of the entry-level cards.

SmartShader

This technology will unleash a new generation of visual effects on your computer. Realistic graphics with breathtaking 3D effects are possible with SmartShader. DVD movies can be viewed to better effect with it too.

SmartVision®

SmartVision® has the effect of removing jagged edges, improving the image, bringing its finer details to light.

Fullstream

This is the latest technology in video processing, which is particularly for the Internet and video playback processing. It greatly improves the quality and performance of streaming video.

Discount Computer Accessories

2008-12-01T20:00:00.001-08:00

Writen by Josh Riverside

An accessory is an additional item for a product that helps in contributing to its utility. There are many accessories available today that add useful functionalities to a computer. In a market cluttered with many different products, brands and types of accessories, a buyer has a tough time in selecting the right ones for his computer. Some accessories come along with the computer when it is purchased. There are many others that users purchase separately. Pricing is a key factor while purchasing a computer accessory and therefore, it is common for prospective buyers to shop around for a discount.

There are many reasons why computer manufacturers, dealers and resellers offer discounts on accessories. All manufacturers typically have unsold computers and accessories in their warehouses. To reduce the exposure from unsold items that could become obsolete, they offer discounted rates to clear the stock. Dealers and resellers offer seasonal discounts and promotional offers when the sales are low. Special discount sales are organized for this purpose. These are usually for a limited period of time and are widely advertised. Buyers can find information about such discount sales by visiting the Web sites of manufacturers and dealers.

Discounts are also offered by retailers and wholesalers on products that did not meet internal quality standards. Such products may have been rejected by a quality assurance team from a batch intended for exports. As long as the functionality of the accessory is achieved, many users are satisfied with products with minor defects that may not be visible or perceptible to an average user.

Discounts on accessories such as keyboards, camera batteries, desktops, digital cameras, floppy drives, hard drives, input devices and memory chips are provided when a bulk purchase is made. Large organizations and educational establishments such as colleges and schools purchase large quantities of computer accessories and benefit from wholesale rates.

It is important that a buyer does not make an impulse decision while buying an accessory. The promotional discounts being offered by a manufacturer or a dealer should be weighed by checking the product thoroughly before purchase.

Refurbished Laptop Faqs

2008-11-30T20:00:00.001-08:00

Writen by Max Bellamy

Refurbished laptops are the repaired versions of faulty laptops. They are renovated by the manufacturer and the error free versions are sold in the market at a lower price through remarketing services. These are available even in the most sophisticated models.

How are the laptops refurbished?

The rate of advancement of the computer technology has been increasing at an astonishing pace. Computers of all sorts, from the personal computers to monstrous mainframes, are at work helping individuals from all walks of life. Countless technologies have been created in the past decades and are continuously developed and refined at present. Of these incredible computer-related technological advancements, printing devices have drawn an enormous patronage from consumers.

Printers can be found practically everywhere and come in numerous models and designs. For all the advancements in graphic design, architecture, advertising, and other highly image-conscious industries, more and more printers are being introduced to the market that cater to the different needs of the rising number of consumers. There is an array of printing technologies available nowadays, namely dot-matrix, solid ink, thermal wax transfer, dye sublimation, and by far the top two most widely recognized, laser and inkjet printers.

Inkjet printers and laser printers are marketable because of their wide variations and relatively cheaper prices. A person can choose from scores of models and designs that meet his needs and suit his standards. Laser printers produce images by fusing dry ink or toner and electricity from a controlled laser beam. They can reproduce vibrant outputs in just a short while, although a person has to spend an additional amount for printers with a faster speed and better print quality. Inkjet printers, on the other hand, cost less than most laser printers; operate noiselessly, unlike dot matrix and daisywheel printers; and work without warm-up time as opposed to thermal wax and dye sublimation.

Inkjet technology produces texts and images through "jets" or small nozzles. It makes use of a series of little nozzles through which generated ink droplets are sprayed onto the printing surface, creating an image. The image of the paper is composed of diminutive dots with a resolution ranging from 360 to 720 dots per square inch or "dpi." This technology is riding a surge of popularity for its continuously decreasing price but escalating graphic capacity. As a result, people who are in need of photorealistic-quality color printing but who do not have a lot to spend resort to inkjet printers.
