What is Computer?

A computer is one type of machine manage different kinds of programs to perform useful tasks to the users. Computer gives proper response to the users through the set of instructions arranged in proper order. It has storage capacity along with execution benefits. Computers can perform both complex and simple operations. Based on types of actions, computers design in several formats with hardware and software specifications. Computer contains wires, transistors, circuits, hardware parts and etc. Computer designs with both software and hardware. Software is a process of preparing program through instructions and data. General computers made with following types of components in hardware.

1. CPU

2. Memory

3. I/P Devices

4. O/P Devices

Types of components in hardware.


Central Processing Unit maintains three kinds of activities to store the data and processing data with several kinds of operations. PU is major part to the computer that tells about the computer to perform which task for every time.


Memory is one part that store data, programs and etc. It categorized into several types those can work at special purpose.

I/P devices:

Devices which is useful to provide input data to the computer that will be processed to provide output from other devices.

O/P devices:

Input devices give input to the computers. After process the data of input the proper output will release to the users from output devices.

Computer Types:

1. Personal Computer

2. Mini Computer

3. Main Frame Computer

4. Super Computer

5. Workstation
