Computer System

The components of a computer system are: People Data Procedures Hardware Software

A system is a collection of elements that works together to solve a specific problem.

Regardless of size, every computer needs other components to produce results.

Computer Components

A computer performs three functions:

(i) It accepts data (Input)

(ii) It processes data by performing desired arithmetic and logical

operations (Processing)

(iii) It generates data in the desired form (Output).

Computer Components

Basic components (organization) of a computer system

Computer system consists of five basic components. They are:

(1) Input Unit(2) Memory Unit

(3) Arithmetic Logic Unit (ALU)(4) Output Unit(5) Control Unit

Purposes of the elements of Computer

Computer elements Purposes(1) Input Unit (1) To receive data and instruction in a form that can be understood

by the computer.(2) Output Unit (2) To give out information via a suitable device, i.e., a printer or a

monitor. The output information is obtained from main storage.(3) Arithmetic Logic Unit

(3) To carry out calculations and comparisons based on the instructions.

(4) Control Unit (4) To take stored instructions in sequence one at a time

(5) Memory Unit (5) To hold data and instructions after input unit until needed. Also to hold information waiting output.

Different parts of a computer

CPU: It is the part of the computer that interprets data, executes instructions, and solves arithmetic problems; the main information processor or "brain" of the computer. 

Disk: Drive the mechanism that rotates a storage disk (such as a floppy, hard, or CD-ROM disk) and read or writes data (or both) on a disk medium.

CD-ROM: (compact disk read only memory) a rigid plastic disk that stores a large amount of data through the use of laser optic technology.

Keyboard: a keypad device with buttons or keys that a user presses to enter data, characters and commands into a computer.

Modem: The place where the computer is connected to the phone line.

Different parts of a computer

Monitor: A display screen to provide “output” to the user. It is where you view the information your are working on. 

Motherboard: the main board of a computer, containing the primary components for the central processing unit, main memory, keyboard, monitor, and often having slots for accepting additional circuitry.

Touchpad: A pressure-sensitive and motion sensitive device used in place of a mouse.

CD: Compact Disk – A type of optical storage device.

Speakers: Used to generate or reproduce voice, music, and other sounds.

Sound Card: Connects the speakers and microphone to the computer.
