Component of the Computer System

Components of the Computer System

These are those things that makes up the computer system

1.    Hardware

2.    Software

3.    Lifeware/Peopleware/Humanware

Hardware: These are those parts of the computer system that can be felt seen and touched e.g monitor, keyboard, mouse, CPU, etc.

Monitor: The monitor displays the content and operations of the computer (Central Processing Unit) it is also known as Visual Display Unit (VDU).

Keyboard: This is an input device that allows the user to communicate with the computer.

 
Mouse: Mouse is another input device that allows the user to interact with the computer.

CPU (Central Processing Unit): This is where the internal components of the computer are

stored and it is also the main brain of the computer.

The hardware is subdivided into three units namely:

1.    Input unit

2.    System processing unit

3.    Output unit

Input Unit: These are the unit that enables the user to interact or communicate with the computer system e.g keyboard, mouse, joy-stick, light-pen.

System Processing Unit: This is a metal box that contains the C.P.U, mobo/mother  board/main board, FDD, HDD, CDD, PCB

FDD – Floppy disk drive

HDD – Hard disk drive

CDD – Compact disk drive

PCB – Printable circuit board

The system unit comes in two forms i.e

1.    The  Tower type

2.    The Desktop type

Output unit: It is the unit through which the computer communicates back to the user e.g printer, plotter, speaker, monitor, projector etc.
