Performance of a Computer System

Hard Drive:

The hard disk drive is a storage device that stores all files and information. It contains a read-write mechanism and has one or more hard disks in them. It also still is in power when the machine is off therefore all will still be there and there permanent until  we do otherwise.

Graphics Card:

A graphics card or video card is an expansion card which generates output images to a display.

These can improve the quality of an image on display and can also improve the gaming performance. A top-of-the-line graphics card is easy to spot. It has lots of memory and a fast processor.

Processor:

A processor is also known as a CPU chip. This processes the instructions for creating and manipulating a digital graphic.

Processors work hard to do the creating and manipulating that you need to do for an image etc.   Duel core and quad core processors are much faster than a single, therefore the performance is much better.

RAM:

RAM which stands for Random Access Memory is  Data is stored on a memory module to save and retrieve quickly.

Primary storage of Data and instruction used by the processor.

RAM is high speed and more Ram will improve the performance of the computer, therefore the more Ram the better.
