Device Drivers

Not many people know about device drivers until they need to find one, be it for a printer or most commonly a modem driver. Finding one can be very difficult to say the least if you are using HSP based modem drivers.

What is a Device Driver?

Every device, be it be a printer, modem, or keyboard, must have a driver program. Many device drivers, such as the keyboard driver, come with the operating system. For other devices, you may need to load a new driver when you connect the device to your computer. Note that in the older DOS systems, drivers are files with a.SYS extension. now in Windows environments, drivers often have a.DRV extension.

What do they do?

A device driver is nothing more than a glorified translator which fits between the device and programs that use the device. Each device be it a modem or printer has its own set of commands that only its driver knows. That bieng said, however most programs access devices by using generic commands. The device driver, therefore, accepts generic commands from a program and then translates them into specialized commands for the device.

Finding them:

Finding a driver can be very difficult as most manufactures manufacture a device and after 2 or 3 years change and make a different version. Finding a driver for your device becomes a task as the manufactures remove the drivers from their website and refuse to support them. They hope that you will upgrade to their new line of products, but there is no need if you know where to find your drivers. Try the following website which not only has more than 2,000 drivers but finds what you are looking for, free.

Remember, don't upgrade unless you want to. There is no need to buy new, when the old printer or modem worked just fine!

Why Build A Computer?
Building a computer has many benefits over buying a premade. First of all, it is generally cheaper if you build your own than buying one. If you shop your components, your DIY(Do it yourself) computer will be cheaper than its premade equivalent. If you build your own computer, it will be faster than one that is premade, because most computer manufacturers use cheap components and try to cut corners to cut down costs. Additionally, your self built computer has more room to upgrade if you so decide to in the future. Prebuilt computers usually only have enough expansion slots for the components that are going to be in the computer. Because of this, your prebuilt computer will become obsolete sooner. Also, building a computer is a satisfying experience and you will learn more about how your computer works.

How do I go About Building a Computer?
Building a computer is probably much simpler than you think. Especially now, things have been simplified and standardized. First, you pick out components and make sure they are all compatible. Once you get the parts, you put them together! This guide was made to show you how to do everything and contains pictures and good information to make building a computer a fun and rewarding experience.

Avoiding Purchase of Stolen Computers

Most of us purchase used computers for the main reason that they can be purchased for a very lesser amount. When doing so, there is a high risk of purchasing a stolen computer, which can be passed off as a used computer. The incidence of purchasing a stolen computer is more when they are got in the name of used computers from third party computer dealers like the computer dealers online or from a theft store or from a pawnbroker who has no idea about the history of the computer he is selling.

Following measures can be taken to avoid buying a stolen computer:

One of the safe measures while buying used computer is to buy through a credit card or check payment rather than making cash purchase. If the seller insists on cash payment, the purchaser can be very sure that the computer may be a stolen one. Also stolen computers are sold at very low prices. If the buyer has good knowledge about the price trends of computers in the market, he can for sure find out if the computer sold as a used computer is of a genuine kind or not.

The place of buying used computer is of outmost importance as a reputed dealer or seller will have a well-established location. They do not sell on the streets. Hence, it is better to avoid buying used computers from the street side shops, which may be fly by night shops. Such sellers attract the buyers with the pricing or heavy discounts or even freebies along with the computers. If the buyer is not sure about the computer, he can very well ask for the documents pertaining to the computer or can find out if receipts are issued for the purchase. The best method of finding out is to check the serial number of the used computer that can be done with the help of the local law enforcement personnel.

The buyer has all the rights to ask the seller about the reason for the sale of the used computer, where it was purchased and nature of payment made initially. If the buyer is satisfied, he can go ahead with the purchase, else should move on to the next seller. Normally, one can find out if the seller is genuine or not through his body language.
A person selling illegal things will show frenzied movements, will agree even for a rock bottom price with even a small amount of profit for him, mostly will not have a decent language, will try to sell in haste, will always be looking around to find out if someone is watching him and will not have an eye contact while selling and so on.

Such kind of illegal sales of used computers happen as the illegal seller has the facility to advertise free of cost. Also posing as a private seller there is no need to provide a VAT receipt, which makes him free of any legal action being taken against him. Hence it is not advised to buy a used computer without a cash receipt provided by the seller.

Athlon 64 Processors

For a long time Intel has been leading the market in processor sales and popularity but AMD is finally putting a stop to that. With the release of their Athlon 64 processor, with 64 bit computing capabilities, they have been slowly but surely regaining the market back from Intel.

The Athlon 64 processors have been around for a while now and they have proven themselves the market leaders in processing power. As we know AMD processor run at a lot slower speeds than Intel processors making them cooler to run. This has eliminated the need for expensive cooling equipment and opened the doorway for overclocking.

Although AMD hit the target by releasing their 64 bit processor long before Intel did, they are not standing still. They have been constantly upgrading their line up to increase speed and efficiency. This is apparent with their fx series processors and their dual core processors.

The fx series processor are the king of the hill at AMD. They are the most powerful processor that is available. They show blistering speeds for CPU intensive functions such video encoding and gaming. They also show great performance in database driven work and most other aspects of computing.

The dual-core line of processor are the ultimate in multi-tasking. They provide the power of two processor running in unison while still being able to fit in a single processor motherboard. Although these processors are essentially two processors in one, they are rather pricy and may not be everyones cup of tea.

Intel is trying to fight back by forming an alliance with Apple. All macs are now available with Intel processors. Whether this will be profitable for Intel only time will tell.

With competition growing stronger from AMD this can only mean increased benefits for the consumer. As the war between Intel and AMD intensifies, the consumer will benefit from lowered prices, and increased quality in their processors.

A market study of colour printers

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.

A Checklist for Used Computers

It is very important to check a used computer thoroughly before buying it as it may lead to problems in the future. A hard drive will not show any outward signs but may be deteriorating. The same way the needle can suddenly slip and can cause scratches on the disc ultimately leading to memory loss as used computers can fail any time. If they are checked, the faults which may occur can be known. Let us first see the possible faults which may occur while purchasing a used computer.

Hard disk failures can happen due to heavy wear and tear over a period of time. The read and write heads of a hard disk are used to retrieve or recode data stored on the hard disk with the help of a disk platter rotating at a high speed. Over a period of time the risk of failure or malfunction of disk increases. Faulty sectors of the hard disks can be found out only if a full surface scan is done on the used computer. The scanning time depends on the capacity and size of the hard disk of the used computer. Many skip this procedure due to the time consuming process of scanning the whole disk and end up purchasing a used computer with a faulty sector.

Monitors need to be checked for any faults. The malfunctioning of a monitor is called a “dry joint” which results in the monitor not working after getting warmed. This can be checked only if the monitor is made to work for at least 20 to 30 minutes after switching on the computer.

Next is to look for any possibilities of the central processing unit getting freezed. Normally all the central processing units have a fan and heat sink for keeping the unit cool. Over a period of time the fans may not work properly due to the accumulation of dust and dirt resulting in over heating of the central processing unit and even leading to stopping from functioning. While buying a used computer the fan needs to be checked and if any abnormal sound is heard, it is not good for purchase.

The used computer may have a higher possibility of getting crashed and freezed due to the usage of the operating system for a good number of years. There may be a cache or RAM fault due to the over exposure leading to loss of data. To increase the performance of the computer and to avoid crashing, the operating system of the used computer can be reinstalled with a new operating system or a fresh one.

While checking the used computers for any faults, it is good to disconnect the network connection if any present before performing the tests. Also it is advisable to check the drives like the CD or DVD by opening and closing them and also playing something on the drives to see how they work. Monitors of the used computers can be checked for the resolution and brightness by trying different options of color, settings and so on. To check the hard disk size the CMOS setup can be gone through and to verify the speed of the processor, cache and RAM the pause button is pressed when it appears on the screen during the booting process. To check the booting process, the computer can be turned on and off a few times and seen how it responds. Checking should be done to see if all the passwords are erased before purchasing a used computer.

7 Barebones Computer Buying Tips

Getting a new computer should be a cool thing, especially a cheap computer. After all that time struggling with you old machine, probably fighting with it to get the latest software to run, your new computer should be a ray of light for your computing future.

Oh, if it were that simple. If things were really that easy or simple when buying a cheap computer, life would be much easier, but just like every other thing, its not that simple.

Barebones computers have become extremely popular, and for good reason. Getting a barebones computer which does not include a monitor and comes with the bear minimum of parts makes them an upgradable, practical and cheap computer.

But not all things are rosy in barebones computer land...

1. Missing parts

Although barebones computers do come with the essential pieces, most people need at least one or two extras for their day to day barebones system. This is simply due to different applications people use them for. Don't get caught missing that extra part from your barebones system that you then need to get later. You still need to do some homework and research to find out what you really need from your barebones system.

2. Super cheap computer deals

Beware, many corners can be cut to get those sub $200 dollar barebones systems. They can be great, but not always, carefully analyse the components of the package. Also remember that a barebones system couldn't possibly include a monitor for that price, which adds a lot to the price.

3. Mismatched parts

This could become a problem if building your own computer, but it even happens in pre-assembled barebones computer deals. There is a chance that you get something that doesn't fit with the barebones system. There are lots of different connections and speed ratings between parts. Make sure the ones you get match up to the other parts and your needs. Although not common, incompatibilities between parts are not unheard of.

4. Outdated components

To get super-cheap deals older parts are sometimes used in cheap computers. Although this can be a great cost-saver and some old parts are fantastic, there is nearly no chance of an upgrade without putting a major amount of money into your barebones computer again, perhaps as much if not probably more than you paid for your great deal.

5. Defective parts

Although this is another one that has gotten better as the competition has gotten stronger, there is a chance of defects in cheaper products. Your motherboard could be faulty, your power supply might give up after a month or two. These may not be intentional problems, but come hand in hand with "cheap computer stuff".

6.Refurbished computer parts

Refurbished computer parts are a great way to save some money. Not always the biggest saver, but there can be problems with the updates to these computers in much the way as mismatches happen in barebones systems. Often the computer is slightly updated to meet needs, but is really quite an old model, just with upgrades. Can be fine, but the parts they replace might be replaced with something newer but inferior.

7. Claims of great warranty

To try and entice you into feeling safe, offers of long warranties are made. Most of the parts in the computer could have past their warranty dates, so the warranties are purely from the company that put the computer together. They can be hard to contact and take their time to get replacements to you as well as expect you to mail the computer to them so that they can do the repairs.

Barebones computers can be a great way to put together a second computer, build a computer for simple purposes, like writing documents and casual web surfing. Barebones fit perfectly as a second computer. Just keep these things in mind and you won't get bitten by the bargain bin monster.

6 Tips to Save on Your Printer Ink Cartridges

Buying a printer is a one time cost, but since printer ink cartridges need to be bought on a regular basis, the cost of operating the printer and maintaining it in proper condition can add up. Each ‘print’ command, however small, makes your printer use ink, but with some easy tips, you can actually save a lot of ink and use a cartridge for a longer period than usual.

1) Print only what is necessary

Let’s begin with economising. Most often, we end up making unnecessary printouts and in the process waste precious ink. For instance, you might need to print only a small portion of a web page instead of the whole page. Instead of simply printing the whole page, complete with its heavy graphics etc, be specific on what you want to have in hard copy and print only that portion.

Text always consumes less ink compared to graphics or images. If textual information is all that you need then you can make sure that you don’t print the graphics and images. If it is a web page you need to save in a printed form, check for its print version. If there is no print version, you can copy and paste the text in a word document and take a printout of that.

Also try to do a bit of planning and double check what you are printing before hitting the print button.

2) Go for a quick print preview

Most branded printers such as HP, Canon, Dell, Epson or any other printer come with a printer driver which has a very useful print preview function. With this function, you can have a prior preview of the copy you want to take a print out of.

This function is especially handy when you are directly taking the print out from the Internet. At times, what you see on a site is totally different as compared to the printed version. A quick preview can help to get the printout of the material that you specifically want.

3) Make sure the power is turned off

Just as you never switch off your computer without properly shutting it down, the same rule applies to your printer too. If you don’t shut down the printer properly, the print heads will remain directly exposed to air causing the ink to dry in the nozzles which, in turn, could affect the quality of printing adversely. Make it a habit to check the position of the print heads before cutting off the power.

4) Use good software

There are various ink saving software options available online. These software applications are designed to reduce the consumption of your printer ink. With these applications, you can get good quality printout copies with less ink consumption even during high resolution printing.

5) Use printer ink cartridges smartly

If you don’t do printing regularly, run a small printing test at least once a week, to avoid the ink cartridges from drying up. This little precaution will help you to increase the life of the cartridge.

6) Never expose your printer to extreme temperatures

Too much variation in room temperature is bad for printer ink cartridges. You must avoid keeping your printer in too hot or too cold a temperature as the cartridges can dry up. For lasting printer performance, make sure the room has a normal and stable temperature.

With these small but important tips, your printer ink cartridges will get a longer life. It is easy to buy good quality printer ink cartridges at excellent prices from online shops.

5 Ways To Find Cheap Used Laptops

There are many reason why one would want to buy cheap used laptops, the main, and most obvious reason being that a new laptop is simply too expensive. If your goal is to find a cheap used laptop, then take some time to do the research, and you will be sure to get a great deal. I will detail 5 ways you can use to locate the right used laptop that suits your needs, and price range.

One of the first steps in your research should be to get on the Internet and begin your search. Your first stop should be eBay. Unless you've been living under a rock for the past few years, you already know that eBay is an auction site where you bid for items. It's also a great place to find hard to find items such as, a piece of toast with a religious icon burned into it, or a clip Elvis's sideburns. But, it's also a great place to find inexpensive used equipment, i.e. laptops.

Once on eBay, you can do a quick search by typing “used laptop” into the search function. You're sure to find hundreds of selections, and name brands too. Spend some time there conducting your research. You don't have to bid right away so take your time. Compare prices, and look for sellers with good ratings. The higher the rating, the more reputable the seller.

Another place to find used laptops is Amazon.com. Amazon is not only a great bargain store that sells new items—you can also find used items for sale at a great price, often a lot cheaper than their respective new items. If you've used Amazon before, then you've probably seen the links “new & used.” By clicking on this link when you do a search, you'll be able to see both options. But of course we're interested in used. You'll be given the prices for the used items, as well as its condition, and the rating of the seller.

Still another stop you should make before concluding your research is Craig's List. This website is much like a newspaper classified section in its apparent simplicity. But don't let that simplicity fool you. Do a search for “used laptop” and you will find a huge selection. You can even choose by location to find something local, or you can opt to expand your search to other regions if you wish. One bad thing about Craig's List is that it doesn't include a seller's rating, so you have to be careful. One way to avoid being scammed this is to stick to buying locally, where you can have potential face-to-face interaction with the seller.

One more place where you can try to find cheap used laptops is Overstock.com. Although this site won't yield as much of a selection as eBay, or Graig's List, and perhaps even fewer than Amazon, it's still a good place to look. You may find something in there you didn't see in any of the other sites, so it won't hurt to look.

You don't have to limit your search to the Internet. You can also try doing a bit of off line research. Look in your local newspaper and see what turns up. Often times, some people will opt to sell their used computers by placing ads in the newspaper, so you may be pleasantly surprised by what you find. Try the Sunday paper since it usually has a larger classified section.

There you have it—5 ways to look for cheap used laptops. By doing some thorough research, you're sure to find a great deal. With all of the selections you'll have at your disposal, you'll be able to find a laptop that has the features you're searching for, at a price range you're comfortable with.

5 Tips To Buying Ink Cartridges For Printers

$As a general rule, black ink cartridges are more affordable than color toner. When considering which to purchase, take a moment to think about how you will be using your printer. Will your printouts require color or will they work just as well in black & white? If the answer is ‘yes,’ you will save a considerable amount of money in purchasing the black ink cartridges.

$If you are cost conscious and also have a great concern for the environment, purchasing recycled ink cartridges may be your best bet. Not only are these more affordable, but they are also better for the environment as are other recycled products. One of the best places for purchasing quality recycled ink cartridges is Viking Office Products and Staples.

$When you purchase any type of ink cartridge, make sure that it is compatible with your printer. Many people are surprised to learn that ink cartridges are designed to be used with a specific model and manufacturer of printers, which should be clearly explained on the outside packaging. If you have trouble remembering the model number on your printer, simply write it down on a piece of paper and take it to the store with you. This will be the single most important information to have on hand when selecting ink cartridges for printers because without the right printer model number, you are not likely to get the right product.

$Because ink cartridges are sometimes very expensive, it is often possible to find a real bargain on a printer/ink cartridge combo. A recent visit to a local retail store revealed a single ink cartridge for $29.97. Just beside the ink cartridge selection were several boxed printers. Among them, a new printer and color ink cartridge combo, which was priced at just $34.95. When you consider the difference of only $5.00 and the fact that you could purchase a brand new printer and ink for almost the same price as a single ink cartridge, the better deal was obvious. In this scenario, you could simply resale your former printer on eBay and replace it with the new printer. This just goes to show that a little smart shopping can go a long way in terms of getting the best value for your dollar.

$The majority of ink cartridges for printers carry a manufacturer’s warranty guaranteeing your satisfaction. The only way to receive coverage as promised is to retain the original purchase receipt, ink cartridge packaging and warranty information. If your new ink cartridge should fail to work as promised, most manufacturer’s will either replace the cartridge at no cost to you or refund the original purchase price in it’s entirety.
