A Brief Review To The Insides Of Desktop Pcs

By Andrew Johnson

The desktop PC has come a long way in a short space of time. Currently there are two main operating systems used, these being either Windows or Macintosh, although there are more.

There are many components underneath the cover of the PC that enable it to do the things it does and all of them are feats of engineering genius in themselves. Such is the way that a PC works that replaces just one of them can improve speed and performance greatly.

The processor is the part of the PC that does the thinking, the brain if you will. As you would expect for a brain it doesn't come cheap, if you were looking to upgrade the processor in your system you will probably find it cheaper to replace the whole thing such is their individual expense. The thing you need to know about the processor is, is that is completes the tasks that you and the operating system set it for example 2 + 2=4. The difference between processors is the speed at which they can do these tasks. The faster the rate the processor operates the faster it can perform tasks and the more expensive it is.

The motherboard connects the processor to all the other components of the PC. You can think of it as the switchboard of the PC connecting calls between the different parts. The differences between motherboards is the number of connections it has i. E. How many things you can connect to it and the speed and number of calls it can transfer and connect.

The RAM is like the to-do list for the processor. The tasks are sent from the operating system and placed in the RAM until the processor gets to them. The more RAM you have the greater number of tasks the Processor can be asked to do at the same time.

The hard drive stores all the data that the PC needs. The data is referenced by the operating system so that is can easily access it when required. The cost of hard drives relies mostly on size but the speed at which the data can be retrieved from them is also a factor.

All desktop PCs now contain DVD drives. DVD drives have the ability to play most kinds of discs in and the operating systems have most of the software that is required to play them.

Some connections on a desktop PC are USB, DVI, Audio out and PS/2. The USB connections are useful for connecting detachable drives such as USB pens or webcams. DVI is a digital interface connection that can be used to connect up a monitor or TV. The audio out socket is the connection that leads to the speakers this is generally green on color coded machines. The PS/2 connections are used for a wired keyboard and mouse the keyboard is purple and the mouse is green.

Prices for desktop PCs start from around $350 and can exceed $5000. There is such a variety of specifications available for sale that the price you can pay really does depend on the specific needs that you have. - 30430
