Types Of Computer


1) DIGITAL COMPUTER :

This type of computer manipulates digital and perform arithmetic and logical operations on that data. A digital device directly counts numbers, that represent numbers, letters and other special symbols.

a) MICRO COMPUTER :

A micro computer is a computer whose CPU is micro processor. A micro processor is a processor all of those components are on a single Integrated circuit. It can be divided into two types.

i)  Home Computer
ii) Personal Computer

i) HOME COMPUTER :

Home computer are meant for habits rather than professionals. This consist of a keyboard integrated with CPU in one box type thing and interfaced with ordinary Television and audio cassettes. They are meant for entertainment and training. Some popular home computers were ZX-81, Apple -II, New Brain.

ii) PERSONAL COMPUTER :

These are so called because they are designed for personal use of individual small business. They are meant for professionals, small business units and office automation system.

b) MINI COMPUTER :

The mini computer (Nearly 1960s) became a multi user or shared system speed of execution, Instruction, repertoire, memory size and other characters of mini computers increased with advances in technology.

c) MAINFRAME COMPUTER :

These are large machines with terminals meant to be used by a number of users. They have memory and support both multi user and multi tasking capabilities. They also support a large number of external peripheral devices.

           Their processing speed ranges in between 1 to 10 million instruction per second and can support nearly 100 users in time sharing mode. They are generally used in large computation intensive, scientific and engineering problem and large scale commercial applications. 

d) SUPER COMPUTER :

The Supper Computer are the fastest computers ever made and solve a range of large scale problems which requires extensive numeric computations. They have more than one processor to process the data. It can work in random to produce a billion or more scientific and arithmetic operations every second. These are used in Weather Forecasting, Aerodynamic, Designing, Missile Technology, Oceanology,Geology and in various other scientific avenues.

2) ANALOG COMPUTER :

An Analog computer measures continuously changing physical condition such as temperature and pressure and convert them into quantities. For example thermometer it can change heat into numbers. We take the example of Do Meters or Milo Meters in a car, is a particular type of computer. It is taking the rotation of wheels and turning in into measure of distance.

3) HYBRID COMPUTER :

Hybrid computer utilise best qualities of both the digital and analog computer and are mostly used for machines or for individuals process control in Industries.
