Components of a Computer System

Information is funny stuff. The information for the web page you are looking at is recorded on a hard disk inside a computer located in New Britain, Connecticut. The information was copied from physical device to physical device perhaps hundreds of times before it got to your computer where a program used it to display these words on your monitor. Clearly the information is something separate from the devices used to store and transmit it.

A computer system consists of both hardware and software components.

The hardware components of a computer system are the electronic and mechanical parts.
The software components of a computer system are the data and the computer programs.

The major hardware components of a computer system are:

For typical desktop computers, the processor, main memory, secondary memory, power supply, and supporting hardware are housed in a metal case. Many of the components are connected to the main circuit board of the computer, called the motherboard. The power supply supplies power for most of the components. Various input devices (such as the keyboard) and output devices (such as the monitor) are attached through connectors at the rear of the case.
