CLASSIFICATION OF COMPUTERS

Computers can be classified based on the following criteria

Development of technology (by generation)
Principle of operation (by type)
Storage capacity or by configuration (by size)
Degree of versatility (by purpose)

Classification by types

Computers can be classified into three major types based on principles of operations.

The three types are

Digital computer
Analog computer
Hybrid computer
i) Digital Computer: These are computer that perform calculation and logical operations with quantities represented as digits in binary number system. They operate on digital data such as numbers which are referred to discrete values. Digital computers give more accurate and faster results. They are counting devices. Examples are digital clocks, mobile phones, calculations, microcomputers, etc.

They are four classifications of a computer by size name:

(i) Microcomputer

 (ii) Minicomputer

(iii) Mainframe computer

(iv) Supercomputer

Micro Computer: A microcomputer is the smallest computer that has a processor on a single silicon chip. Its CPU is a microprocessor chip. Examples of microcomputers are personal computers (PC), laptop computers, desktop computers, palmtop computers, etc.

(i) Digital Computer: This is the type of computer in which data are represented in digital or in discrete form, for example, 0, 1,2,3,4,5, etc. It is a type of computer that is used for processing numeric information.
