What is the CPU and its function

The CPU (Central Processing Unit) is a microchip, classed as the brain of the computer. Its job is to interpret the instructions that come from the hardware and software, so that the hardware and software can communicate with each other for example. CPUs have different types (Celeron, Pentium, AMD and so on) and different speeds (600Mhz, 700Mhz, 1.79 (1,790Mhz) and so on). The CPU is one of the main reasons for buying a computer. The faster the CPU can process instructions the faster the computer. However. This is not strictly true. An Intel Pentium 4 is faster than an Intel Pentium 3, in theory. And the “stripped down version” of the Intel Pentium 4 – the Celeron CPU – is supposed to be faster than the Intel Pentium 3. I say supposed and in theory because it depends how you slow the computer down or speed it up.

An Intel Pentium 2 with a 7200rpm hard drive is faster than an Intel Pentium 2 with a 5400rpm hard drive. And Windows 98SE with 256 MegaBytes of memory is faster than Windows 98SE with only 64 MegaBytes of memory. So far this is as expected. However. You can have a Pentium 2 with 256MB of memory and a 7200rpm hard drive that will be faster than a Pentium 3 with only 64MB of memory and a 5400rpm hard drive. This is because even though the Pentium 2 processes instructions slower the instructions are being put into memory a lot quicker. For example. If a Microsoft Word file on the hard drive is being copied into memory, perhaps for printing and/or editing purposes, the copying might be done at 1MB intervals. Whereas when Windows 98SE knows it has more memory it knows it can copy data at 2MB intervals for example. With a faster hard drive as well moving files, installing software, file indexing and so on also becomes faster. So the memory and hard drive make up for the slow CPU.

With time and progress manufacturers have now made it possible for the CPU to be split up into two or four parts (cores), known as Dual Core and Quad Core respectively, which basically means the CPU now has two or four brains to use. These core CPUs spread tasks amonst themselvesFind Article, making it possible for one brain (core) to print out a document for example while another brain (core) takes care of processing internet tasks for example.

Computers don’t run so fast as it is new over time. In most cases, computer users take good care of their computer. They install antivirus software to keep the computer away from viruses. The folders are arranged in good order regularly. The recycle bin is emptied in time. It is confusing for many computer users about why the computer runs more and more slowly. This article will explain why the new computer responds more and more slowly and will discuss how to speed up a slow computer.

In normal conditions, if there is no error message or any other problem, the computer gets slower over time because the accumulation of some unneeded files. When you uninstall some programs, you thought it was uninstalled completely and in fact, it was not. There are still some remnants left. These redundant things can’t affect the computer speed instantly. However, it will influence the computer overall performance to a large extent if this can’t be cleaned regularly.

It is not difficult to understand that the computer slowness because of this. Sometimes, it takes much longer to boot up. It is because the programs that start with the computer operating system become more and more. When you install a program, it often asks you whether you want it to start up with Windows. This is often overlooked and as a result, every new installed program starts up with Windows. Consequently, the computer starts up more and more slowly.

Now Windows registry needs to be explained in a simple way. It records all the information of the computer and of course it is the most important part of the computer. For example, there are records when you install or uninstall a program on the computer. There are some empty keys with time passing by. If they are not deleted, the computer speed is also affected.

Guide to Computer Desk

Modern office furniture has to be modular, movable and flexible.

The most important feature of a good computer desk is ergonomic design. As people work spend more hours at the computer, it is important that the desks are comfortable to sit at for long hours.  Moreover, they have to look good and blend in well with the rest of the office or home.  As greater comfort ensures greater productivity, companies are more willing to provide the best computer desks for employees.

Modular computers desks provide flexibility and versatility in use – they can be remodeled very easily depending on the use. These are ideal for the limited office spaces of today, and also work well in homes because they can be easily changed according to different requirements. Fittings are provided to accommodate various other accessories that may be required while using the computer, such as a document holder, wrist rest, file hangers, CD holders, or telephone shelf. Such desks are also often accompanied by a manual that contains comprehensive instructions for assembling or disassembling the unit. On the whole, computer desks today are leaner, and have fewer drawers and more shelf-space than before.

In most modern computer desks, the unique arrangement of the panel systems ensures optimum space, privacy and advanced wire management. The spine of the desk should be designed to not only provide power and data to the whole unit but also to support the desk assemblies, staking storage, divisional screens, transfer screens and other accessories. The end result is optimal space utilization.

A versatile computer desk should not necessarily compromise style.  Computer desks are being designed with every kind of material possible ranging from traditional oak and wood to metalPsychology Articles, glass and fiber.

Tips Essential Computer Buying

Despite years of advancement, the fundamentals of the computer have not changed much. These computer buying tips will give you what you need to know and enough to keep you in the know for many years to come, no matter what the price, or type of computer.

Being at the head of the pack is a costly place to be. So, if money and your budget are any concern to you, then don’t chase the latest fads. The newest stuff carries a huge price premium when older products have not yet passed their prime. Wait a few months for excitement to die down and see what happens, you might have saved yourself from making a big mistake. Getting the biggest thing from a few months back will get you a lot more for your money.

Research before you buy. Don’t get a computer or add extras to a computer without getting the facts first. Sales staff are just that, salespeople, they will do their best, but often know only a little more than you do about what you plan to get. The Internet has a whole wealth of info available, and you can research as much as makes you happy.

Computers are more about the internals than the externals.

As with the computer in general, the CPU is a costly component. The fastest processor will cost you more and value for money goes down as the speed goes up. Up to the middle of the range in speed you will get the most speed per dollar.

More RAM is a good thing. Having the latest super-duper CPU won’t help if your computer runs out of memory. Memory is essential for Windows and all the programs that run on it. When Windows starts it puts lots of things it needs in memory, and they stay there. All the other programs you start also use some memory and keep it until they stop, the more programs you want to use at the same time, the more memory you’ll need. Just make sure you get 512MB or more for Windows XP and 1GB or more for Windows Vista.

Great looking cases that are hidden under a desk or in a cabinet won’t get noticed. Are the USB and sound ports at the front for easy access and are they placed in an easy to reach position?

Hard drives should have enough space. I find 120GB enough, but you might need more if you save videos on there. RAID 1 keeps a mirror image of your hard drive at all times, so if one drive fails, you still have one with your data.

The key to good graphics is the graphics card. The latest games require them cutting edge cards, so get one to suit what you want to play. Games constantly push the demands on the graphics card, and if you want to keep up, you will be upgrading often.

Finally, the monitor is what you will stare at while using the computer. Wider and larger screens allow more stuff to fit on the screen. LCD is the norm, 19 inch or bigger, wide screen if possible is what I recommend.

Understanding the Basics of Computer Processes

When you give an instruction to the computer such as when you click on an icon or you use the keyboard to type something, you are telling your computer what to do. Any set of instructions that you give your computer is in fact a program. When the computer executes these instructions, we call the execution of these instructions as computer processes.

Every different operating system will have its own set of process names and software that execute in a different way. Every program may require several processes to make it run successfully. When the computer is being used, there are several programs that run simultaneously and the computer is able to execute several instructions one after another without wasting its own resources and your time.

In very simple words, computer programs have the ability to multi-task and the processes are switched by the computer’s processors without the user even coming to know about any change in the process execution.

Processes in the computer system are further categorized or divided into threads. These threads remain active as long as the processes are being executed. As soon as the processes are terminated, the threads are also terminated.

Sometimes, certain processes take up a lot of resources of the computer’s processor. This will make the computer to run very slow. At times, without your being aware of it, some process may be activated in your computer that could occupy the processor and in turn affect the working of the other programs in the computer.

If you find your computer freezing or stopping on its own, there is surely some malfunctioning of the computer processes. This could be due to spyware, malwareArticle Search, viruses or Trojans that could have found their way into your computer system.

The simplest thing to do when you are not sure if a program is genuine or unwanted is to stop it from running. This can be done by ending the process using the Task Manager. You can also use the End Task option by clicking on the Go To Process link when you right click on the application.
