. Classified according to the scale of the computer system: The so-called scale of the computer system mainly refers to the speed, capacity and function of the computer. Generally, it can be divided into giant machines, mainframes, small and medium-sized machines, microcomputers and workstations, etc. Among them, Workstation is an engineering-oriented computer system between small computers and microcomputers.

3. According to the type of data processed, it can be divided into analog computers, digital computers and hybrid computers, etc. 1. Large-scale general-purpose computers have extremely strong comprehensive processing capacity and great performance coverage.Dozens of microcomputers or microcomputer chips can be used in a mainframe to complete specific operations.

What are the types of computer systems?

1. The main computer system is UNIX. UNIX is a powerful multi-user, multi-tasking operating system that supports a variety of processor architectures. According to the classification of the operating system, it is a time-sharing operating system. UNIX was first developed by Ken Thompson and Dennis Ritchie in 1969 at Bell Labs at AT&T in the United States.

2. DOS dos is an abbreviation of disk operating system and a kind of operating system on a personal computer. The family includes MS-DOS, PC-DOS, DR-DOS, PTS-DOS, ROM-DOS, JM-OS, etc., among which MS-DOS is the most famous.

3. Linux system To be precise, Linux should be an operating system that conforms to the UNIX specification. Linix is developed based on the source code. Linux is a UNIX-like operating system that is free to use and freely distributed. This system is designed and implemented by thousands of programmers around the world.

What parts does the computer system consist of?

1. The computer system is composed of: controller, operator, memory, input device and output device.Controller: the control system of the computer. The computer controller is the nerve center of the computer, which directs the automatic coordination of various parts of the whole machine.

2. The computer system is divided into two parts: hardware system and software system. The hardware system is mainly composed of central processor, memory, input and output control system and various external devices. ( 1) The central processor is the main component of high-speed computing processing of information, and its processing speed can reach more than hundreds of millions of operations per second.

3. The five major components of the computer hardware system are composed of operator, controller, memory, input device and output device. Controller The controller analyzes the input instructions and uniformly controls the components of the computer to complete certain tasks.

4. The hardware that constitutes the computerThe piece system is usually composed of "five major parts": input device, output device, memory, operator and controller. Input device: Transport data, programs, text symbols, images, sounds and other information to the computer. Commonly used input devices include keyboard, mouse, touch screen, digital converter, etc.
