A Starter Guide To Pc Desktops And How They Function

By Andrew Johnson

The most revolutionary invention of the 21st century is the PC desktops. Since their introduction into society they have become a necessity for modern living, so much so that the government has set a goal to introduce a PC into every household within the next few years.

It's no good having all this processing power if you have no way to utilize it! That's where the operating system comes in. This piece of software allows the user to control the hardware to their desire.

Currently the two main operating systems available are Windows and Macintosh. Although they effectively do the same thing, they are used differently. Windows is tailored more for the family and business market, with its easy to use interface but capable of quickly and efficiently running many in house software created by business'.

Macintosh's however have become more tailored for the designer allowing various graphic design packages to run much quicker than a Windows counterpart.

The Desktop PC consists of a host of components. For a PC to run properly all of its components must be in full working order if any of them are corrupt the PC can stop working or run much slower, such is the complexity of their design. Most common problems lie with the hard drive this is the disk that all the data produced on or imported to the computer is stored. As this item is constantly being used by the system it endures a lot of wear this coupled with the fact it is of mechanical design gives rise to the reason for this being the most problematic area.

Other items a PC needs to run are a graphics card, RAM, power unit and of course the processor, without these the system will not run. There are many other additions that can be added to a PC they range from DVD-ROM drives to webcams. The most expensive item to replace within the PC is the processor, unbelievably to replace they can cost more than the complete system itself.

PC desktops vary greatly in price as the specifications of them can be very different. The cheaper systems you will find use older technology that has been modified to be as quick as possible this means that after a year or two instead of being able to replace one or two parts of the PC you may find you need to replace the majority of it. I would suggest buying at least a mid-range PC if you can as these will last for a good few years and then there is the option of upgrading them as well prolonging its life for a further year or two. - 30430
