What are the three types of computers ?
Define each with examples.
Answers
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)
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.
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.
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.
Desktop computers are not built to be mobile. They are moved, but only to a new desktop location and with the power supply inactive. There are a number of major differences between computers that are intended to be used in one place as a desktop and portables or mobiles that can be easily moved from one location to another. Desktop computers are large and heavy in comparison to portables. They can be carried in specially manufactured cases, but only to assist a support engineer in moving, not as a frequent procedure. The monitor, keyboard and mouse are all separate items on a desktop. Desktop computer components and devices, although quite resilient to movement while active are not made to be constantly moved, even less so when they are operational. A mains power supply is mandatory, as desktop computers cannot work without a constant supply of electrical power. The desktops can further be subdivided depending with the casing type, tower casing and desktop casing.
Explanation:
There are Four Different Computer Types. We have four different computer types classified according to their performance, power, and size. A computer is an electronic device that accepts data, processes it, stores, and then produces an output.
The four basic types of computers are as under:
Supercomputer.
Mainframe Computer.
Minicomputer.
Microcomputer.
