Types of Computer

As you know, Computers can have different sizes, capacity, and usages. Computers are categorized into some categories according to their power, sizes, and usages.

Following is the list of types of Computer:

  • Personal Computer
  • Minicomputer
  • mainframe
  • Workstation
  • Supercomputer

Personal Computer

It is a multi-purpose Computer which comes at the price, size, and capability that is affordable for an ordinary individual.

There is a short form name of the Personal Computer, and that is ‘PC’. IBM introduced the first Personal Computer.

PCs use Microprocessor Technology that makes the size of Computers small. Before Microprocessor was Introduced, The Computers was used to be very large, but When Microprocessor came in existence, It made CPU size smaller because with the help of this technology Computer Manufacturers can put entire CUP on a single chip.

Despite being smaller in size, It has the same capabilities and features as PC.


A Mainframe is also a Computer. We use it for heavy tasks such as data processing and customer statistics.


A workstation is a Computer which is dedicated to professional works, or we can say Workstations are a special kind of computers which is designed for technical or scientific applications.

A Workstation can be used by an individual or a group of people for professional work, It’s also a multitasking machine, and It’s more powerful than a PC.


Supercomputers are very powerful machines which have been used for handling a tremendous amount of database or heavy Computations. In other words, Supercomputers are used for scientific or engineering applications.
