ieee divides computers into 6 categories: personal computer (PC), workstation (WS), minicomputer (MiniComputer), mainframe (MAinfrAme), small supercomputer (MinisuperComputer) and supercomputer (SuperComputer) ).
In 1989, the Institute of Electrical and Electronics Engineers (IEEE) proposed to divide computers into six types, which are personal computers (PC) and workstations (WS). , minicomputer (MiniComputer), mainframe (MAinfrAme), small supercomputer (MinisuperComputer) and supercomputer (SuperComputer).
1. Supercomputer: An expensive, powerful computer with a calculation speed of more than 100 billion times per second is called a supercomputer;
2. Small supercomputer: one price Relatively cheap small-scale supercomputer, also called desktop supercomputer;
3. Host (mainframe, medium-sized computer): The calculation speed of this computer is hundreds of millions to tens of billions per second . It is generally used as the host of a large computing center;
4. Minicomputer: The calculation speed is tens of millions to hundreds of millions of times per second. It is generally used by small and medium-sized enterprises and institutions;
5. Personal computer: also called a microcomputer or PC computer. It is a computer for personal use;
6. Workstation: a model between high-end microcomputers and minicomputers. It is generally equipped with a large-screen display, large-capacity memory, fast speed, and strong communication functions. It is mainly used in professional fields such as image processing or computer-aided design.
Extended information:
The Institute of Electrical and Electronics Engineers (IEEE, full name is Institute of Electrical and Electronics Engineers) is an American association of electronic technology and information science engineers , is the world's largest non-profit professional and technical society, with more than 400,000 members in more than 160 countries. IEEE is committed to the development and research of electrical, electronics, computer engineering and science-related fields. It has developed more than 900 industry standards in the fields of aerospace, information technology, electric power and consumer electronics, and has now developed into a relatively A highly influential international academic organization. In China, 55 universities in Beijing, Shanghai, Xi'an, Wuhan, Zhengzhou and other places have established IEEE student branches.
IEEE is a non-profit scientific and technological society. The organization is a major authority in the academic fields of international computers, telecommunications, biomedicine, electricity and consumer electronics. In the fields of electrical and electronic engineering, computer and control technology, IEEE accounts for nearly 1/3 of the world's published documents.
IEEE has always been committed to promoting the theoretical development and application progress of electrical technology. As a catalyst for scientific and technological innovation, IEEE supports the needs of its members through event programming and services in a wide range of areas.
