The Computer:

The system box is the main part of your PC (IBM Compatible Personal Computer), and consists of:-
a CPU (Processor)
Main Memory
a hard disk drive
a floppy drive (possibly)
CD-ROM and DVD-ROM drives

The main board is called the motherboard that houses connections to the above. Plugged into the motherboard at right angles to it are adapters or expansion cards, which connect things such as microphones and scanners etc. Sound and graphic cards also fit into the motherboard.

There are different ways to study any system. One is by describing each component. In Hardware each component of the PC is described to provide a basic understanding of how each one works. This type of analysis by itself doesn't provide an understanding of the how the PC functions as a unit.

In PC Basics we talk about the different functions in a PC and what they do. At the end we show you the bigger picture where they all come together to make the PC work.



This chart shows the components we've talked about, grouped together functionally. Arrows show how they show how they interconnect.
