A computer is defined as a device, which is capable of carrying out logical or arithmetic operations as instructed by you. It has an input device, which helps it to accept the raw data. This raw data is then processed with the help of instructions called computer programs. The output device then gives you the processed information as the output.

One of the most important features of a computer is that it is capable of storing information and this information can be accessed or retrieved whenever it is required.

The essential components of a computer:

A computer is made up of hardware and software.

  • Hardware:

The hardware of the computer can be defined as the tangible and physical components. They can be seen as well as touched.

  • Software:

The set of programs and instructions that govern how the computer system operates is called the software. The two main categories of software are System software and Application software.

What are the types of computers?

There are four main types of computers and they are as follows:

  • Supercomputer
  • Mainframe computer
  • Minicomputer
  • Microcomputer


These computers are truly super as they give you the best performance. They are powerful when it comes to processing of data. They are used by large organizations since they are specialized and used for specific tasks. They are also used for research purposes.

One of the best examples where supercomputers are used is NASA. NASA uses them for the purpose of space exploration as well as for launching and controlling space shuttles.

Due to their specialized capabilities, supercomputers are large and expensive. Some of them may be even required to be set up in an entire air-conditioned building.

Mainframe computer:

Mainframe computers are capable of processing and storing a large amount of data. They can be as expensive as supercomputers but they do not give the same powerful performance.

Mainframe computers are used by large organizations to run their business. They may be used by government organizations as well.They are large and would need spacious rooms with air conditioning.

Examples of where mainframe computers are widely used are banks, insurance companies and educational institutes. They need to store a large amount of data about their customers, policyholders and students respectively. Hence mainframe computers are the best choice for this purpose.


They are also called midrange computers since small firms or businesses usually use them. These computers are small in size and they are best suited for use by a single department in an organization. Their data storage and processing capabilities are lesser than that of supercomputers or mainframe computers.


These are some of the most widely used computers. They are used in a range of devices such as desktop computers, laptops, smartphones, tablets etc. They are also used in netbooks, notebooks, and calculators. Due to this wide range of uses they are one of the fastest growing computers.

They are extremely affordable and they have been designed keeping work, entertainment and education in mind.
