Is a computer a normal class What are the types of computers?

I wonder what kind of classification you're referring to.

There are several types of computer classifications:1. If computer refers to the professional level, it includes computer science and technology, software engineering, information management and information systems, network engineering, computer application technology, computer network technology, Internet of Things engineering and other majors.

2. If the computer refers to the purpose level, it is divided into general-purpose computer and special computer according to the purpose.

3. If the computer refers to the computer level, the computer is divided into the following five categories according to the comprehensive performance index: high-performance computer, microcomputer, workstation, server, and embedded computer.

Computers are divided into general-purpose computers and special-purpose computers according to their purpose.

According to the 1989 IEEE Science Committee on Giant Computers, it can be divided into giant computers, mainframes, small computers, workstations and microcomputers.

According to the type of data processed, it can be divided into analog computer, digital computer and hybrid computer, etc.

1 Large general-purpose machine.

This type of computer has extremely strong comprehensive processing power and great performance coverage. Dozens of microcomputers or microcomputer chips can be used in a single mainframe to accomplish specific operations. It can support tens of thousands of users at the same time and dozens of large databases.

It is mainly used in ** departments, banks, large companies, large enterprises, etc.

2 Jumbo Machines.

Jumbo machines have extremely high speeds and great capacity. It is used in cutting-edge technology for national defense, space technology, large-scale long-term weather forecasting, oil exploration, etc. At present, such machines can perform tens of billions of operations per second.

This type of computer is developing in two directions technologically: one is to develop high-performance devices, especially to shorten the clock cycle and improve the performance of a single machine.

The second is to use a multi-processor structure to form a hyper-parallel computer, which usually consists of more than 100 processors to form a hyper-parallel supercomputer system, which solves a problem at the same time to achieve the purpose of high-speed computing.

3 Small Machines.

The small machine has a small scale, simple structure, short design and trial production cycle, which is convenient for the timely use of advanced technology, low software development cost, and easy to operate and maintain. They have been widely used in industrial automatic control, large-scale analytical instruments, measuring equipment, enterprise management, universities and scientific research institutions, etc., and can also be used as auxiliary computers for large-scale and supercomputer systems. In recent years, the development of minicomputers has also been noticeable.

Especially RISC

reduced instruction set

As the name suggests, it is a simplified and scaled down computer, while the computers of the past are all CISC (Complex Instruction System Computers).

RISC's idea is to replace complex instructions that are rarely used with subroutines, to limit the entire instruction system to a very small number of basic instructions, and to optimize the compiler for only one clock cycle, or even less, to optimize the compiler and thus improve the overall performance of the machine.

4 Microcomputers.

Microcomputer technology has developed rapidly in the past 10 years, with new products appearing every 2 3 months on average, and products being updated once every 1 2 years. On average, every two years, chip integration can be doubled, performance can be doubled, and performance can be cut in half.

There is a trend of acceleration. Microcomputers have been used in office automation, database management, image recognition, voice recognition, expert systems, multi-technology and other fields, and have begun to become a conventional electrical appliance in urban families.

Computers are traditionally divided into three categories: mainframes, minicomputers, and microcomputers.

The mainframe is generally a high-performance parallel processing system with large storage capacity and strong transaction processing capabilities, which can provide services for many users.

The minicomputer has a certain data processing capacity, provides information services of a certain user scale, and serves as the information service center of the department.

Microcomputer generally refers to the desktop or mobile computing system in the office or home, which is small in size, low in size, has an industrialized standard architecture, and has good compatibility.

1 It can be classified according to the form and processing of information: (1) Electronic digital computer: all information is represented by binary numbers.

2) Electronic analog computer: the internal information form is a continuously changing analog voltage, and the basic operating component is an operational amplifier. (3) Hybrid electronic computer:

It is difficult to design both digital and analog quantities. 2 According to the use, it can be classified as: (1) General purpose machine:

It is suitable for various applications, and is a computer with complete functions and good versatility. (2) Special machine: a computer specially designed to solve a specific problem, such as an industrial control machine, a special bank machine, a supermarket cash register (POS), etc.

3 According to the size of the computer system, the so-called computer system size mainly refers to the speed, capacity and function of the computer. Generally, it can be divided into giant machines, large machines, small and medium-sized computers, micro computers and workstations.

Among them, workstation is an engineering-oriented computer system between a microcomputer and a microcomputer.

Hello, from the perspective of user applications, computers can generally be divided into microcomputers, including: personal computers, PCs; Server; terminal computers, etc.

1. Classified according to performance indicators: giant machine, high speed, large capacity; Mainframe, fast, used in the field of military technology and scientific research; Small machine, simple structure, low cost, outstanding performance; Micro machine, small size, light weight, low size.

2. Classification according to use: special machine, strong pertinence, specific service, special design; General-purpose machine, scientific computing, data processing, process control to solve all kinds of problems.

3. Classified according to the principle: digital machine, fast speed, high precision, automation, and strong versatility; The simulator uses the analog quantity as the amount of operation, which is fast and has poor accuracy; The mixer, which concentrates the advantages of the first two and avoids its disadvantages, is in the development stage.

There are three types, tabletop. Laptops, all-in-one computers.

1. Definition: Computer, commonly known as computer, is a modern electronic computer machine used for high-speed calculation, which can perform numerical calculations, logical calculations, and also has the function of storage and memory. It is a modern intelligent electronic device that can operate according to the program and process massive amounts of data automatically and at high speed.

A computer that consists of a hardware system and a software system without any software installed is called bare metal. It can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers, and the more advanced computers include biological computers, photonic computers, quantum computers, etc.

2. Features: 1. Supercomputer is a type of computer with the strongest function, the fastest computing speed and the largest storage capacity, and is an important symbol of the country's scientific and technological development level and comprehensive national strength. Supercomputers have the strongest parallel computing power, which is mainly used for scientific computing.

Undertake large-scale, high-speed computing tasks in meteorological, military, energy, aerospace, prospecting and other fields.

2. Network computers refer to some high-performance computers that can provide services to the outside world through the network. Compared with ordinary computers, the stability, security, performance and other aspects are higher, so the hardware such as CPU, chipset, memory, disk system, and network is different from ordinary computers.

3. Personal computers, including desktops, computer all-in-one computers, laptops, handheld computers and tablet computers, etc., are relatively poor in terms of running speed, but some can be easily carried and can be used anywhere to meet the needs of all aspects.

4. The embedded system is an application-centric, microprocessor-based, software and hardware can be tailored, and the application system has comprehensive and strict requirements for function, reliability, cost, volume, power consumption, etc., with a wide range of applications to meet the needs of all aspects of society.

5. Industrial control computer is a general term for a computer system that uses a bus structure to detect and control the production process and its mechanical and electrical equipment and process equipment. Abbreviated as industrial computer. It is mainly used in industry and has played an indelible role in the development of industry.

There are many classifications of computers in terms of their type, mode of operation, constituent devices, operating principles, and application conditions.

In terms of data representation, computers can be divided into three categories: digital computers, analog computers, and hybrid computers.

Digital computers are divided into mechanical computers and electromechanical computers, electronic computers, optical computers, quantum computers, biological computers, neural computers, and so on.

Electronic computers can be classified as giant, large, medium, small, and microcomputer in terms of their size or system capabilities.
