According to the scale of computers, computers can be divided into five categories: supercomputer, mainframe, medium-sized computer, minicomputer, and microcomputer. A supercomputer is a very large electronic computer; a mainframe, or mainframe, uses a dedicated processor instruction set, operating system and application software; a microcomputer is a smaller electronic computer composed of large-scale integrated circuits.

According to the scale of computers, computers can be divided into five categories: supercomputer, mainframe, medium-sized computer, minicomputer, and microcomputer.
Supercomputer
Supercomputer (supercomputer, supercomputer) is a very large electronic computer.
A supercomputer is actually a huge computer system, mainly used to undertake large-scale computing projects and data processing tasks in major scientific research, cutting-edge national defense technology and national economy. Such as large-scale weather forecasting, sorting out satellite photos, exploring atomic nuclei, researching intercontinental missiles, spacecraft, etc., formulating national economic development plans, there are many projects, and they are time-sensitive. Various factors must be considered comprehensively, relying on supercomputers can be completed more smoothly.
Mainframe
Mainframe, or mainframe, the English name is mainframe. Mainframes use specialized processor instruction sets, operating systems, and application software. The term mainframe originally referred to a large computer system housed in a very large framed iron box to distinguish it from smaller minicomputers and microcomputers. Most of the time it refers to a series of IBM computers starting with system/360. The term may also be used to refer to compatible systems manufactured by other vendors, such as Amdahl, Hitachi Data Systems (HDS). Some people use this term to refer to IBM's AS/400 or iSeries systems. This usage is inappropriate; because IBM itself only regards these series of machines as mid-range servers, not mainframes.
Minicomputer
Minicomputer refers to a high-performance 64-bit computer that uses a reduced instruction set processor, with performance and price between PC servers and mainframes. computer. The corresponding English names of foreign minicomputers are minicomputer and midrange computer. Midrange computer is relative to mainframe and microcomputer. This term has been mistranslated as midrange computer by some domestic textbooks. The term minicomputer was coined by DEC in 1965. In China, minicomputer is customarily used to refer to UNIX server. In 1971, Bell Labs released the multi-tasking and multi-user operating system UNIX, which was subsequently adopted by some commercial companies and became the mainstream operating system for later servers. This server type is mainly used for industry applications with high reliability for single-point operation of business, such as financial securities and transportation.
Microcomputer
Microcomputer is referred to as "microcomputer" or "microcomputer". Because it has certain functions of the human brain, it is also called "microcomputer" . Microcomputer is a small electronic computer composed of large-scale integrated circuits. It is a bare metal based on a microprocessor, equipped with internal memory, input and output (I/0) interface circuits and corresponding auxiliary circuits.
