Question

Definition of different types of computers

Answer 1

Supercomputers – Supercomputers are very expensive, very fast, and the most powerful computers we have in the world.

Supercomputers are optimized to execute a few number of programs. This makes it possible for them to execute these few programs at a very high speed. Due to their inhibiting cost, they are used in high end places like in scientific research centers. The supercomputer consists of thousands of processors making it clock very high speeds measured by petaflops.

These computer types are also very large in size due to the numerous parts and components involved in their design.

A good example of a Supercomputer is Tianhe-2: TH-IVB-FEP Cluster; National Super Computer Center in Guangzhou, China; 3.12 million cores (33.86 petaflop/s).

Mainframe Computers

2. Mainframe computers — These are large and expensive computer types capable of supporting hundreds, or even thousands, of users simultaneously. Thus, they are mostly used by governments and large organizations for bulk data processing, critical applications, transaction processing, census, industry and consumer statistics among others. They are ranked below supercomputers.

Minicomputers

3. Minicomputers — Minicomputers are mid sized computers. In terms of size and power, minicomputers are ranked below mainframes. A minicomputer is a multiprocessing system capable of supporting from 4 to about 200 users simultaneously.

The use of the term Minicomputer has diminished and they have merged with servers.

Microcomputer

4. Microcomputers or Personal computers – A personal computer is a computer designed to be used by one user at a time.The term microcomputer relates to microprocessor which is used with a personal computer for the purpose of processing data and instruction codes. These are the most common computer types since they are not very expensive.
