What is a Computer?
A Computer is an electronic data processing machine that accepts data, processes them and gives the result/output. A Computer is a machine that can store instructions and execute them. A computer is a machine, so it cannot work itself. A computer performs according to the instructions given by the user. It can perform calculations, draw pictures, read and write data, and do many other works.

Types of Computer

The computer can be classified on the following four basis:

On the basis of Performance /Work.

On the basis of Performance, the computer can be classified in the following three types:

Analog Compute

DigitalComputer

Hybride Computer

Analog Computer

The computer that measures physical values (such as temperature, pressure, current, etc.) is known as Analog Computer This computer represents values as a continuously varying voltage/value. For example, a Speedometer shows changes in speed using a needle indicator that can move over an infinite range of speeds up to the maximum limit of the vehicle.

Digital Computer

The computer that performs using/counting the digits 0 and 1 is known as Digital Computer This computer represents information in discrete form. It is used to perform calculations, draw pictures, etc. The computer you use is Digital Computer.

Hybrid Computer

The computer made by using the combination of both analog and digital computers is known as Hybride Computer This computer can do the tasks of digital as well as analog computers. The hybrid computers attached to the jet planes help the pilots to fly days and nights without any trouble. During the flight, the hybrid computer determines the altitude, air pressure, humidity, distant mountain, landing zone, length of runway, etc.

On the basis of Size

On the basis of Size, the computer can be classified in the following four types:

Mainframe Computer

A large and multiuser computer that is designed to meet the computing needs of a large organization is known Mainframe Computer . The mainframe computer can be used by 100 to 500 users at one time.

Mini Computer

A medium-sized and multiuser computer that is designed to meet the computing needs of a small organization, or a department is known as Mini Computer. The mini computer can be used by 50 to 100 users at one time.

Micro Computer

A computer that is made by using the microprocessor is known as Micro Computer. Micro Computer can be used by one person at a time.

Super Computer

A computer that is designed to run faster than ordinary Mainframe computer is known as Super Computer. The example of Super Computer is Robert.
