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!

Building A Computer Introduction

If you are reading this article, you are probably wondernig, why and how do you build a computer. Building your own computer is more simple than you think and has many benefits.

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.
