Performance of a Computer System

Hard Drive


 The hard disk drive is a storage device within the computer that connects to the motherboard. 

The faster a hard disk is the faster the data will load in a computer and not only will the data load faster but it will somewhat make your computer faster.  The hard drive doesn’t affect much of the performance of your computer simply because it is only a storage data device and is only there to hold your files and software.

Graphics Card/Video Card

A graphics card or a video card is an expansion card which generates output images to display.  A graphics card improves the quality of the image or the quality of the gaming graphics.

A graphics card has no big affect on a computers performance, the only affect it has is after a few months your computer will start to get a bit slow and the graphics wouldn’t be just as good this is because a graphics card needs to be updated after a while.

Processor

 A processor is also known as a central processing unit.  It is a part of the computer that carries out the computers instructions of a computer system.

The processor on affects the performance of documents and pictures etc it does not affect the performance of games.

 RAM
