What are the specific devices that are included in the computer peripherals?

Computer input devices include keyboards, mice, cameras, scanners, light pens, handwriting tablets, joysticks, voice input devices, etc.

1. Mouse (mouse) is a handheld screen coordinate positioning device, which is an input device that adapts to the software and graphics processing environment of menu operation, especially in the current popular Windows graphics operating system environment, the application of mouse is convenient and fast. There are two types of mouse devices commonly used, one is mechanical and the other is photoelectric.

2. Camera (camera or webcam), also known as computer camera, computer eye, electronic eye, etc., is a kind of input device, which is widely used in meetings, telemedicine and real-time monitoring.

3. Scanner is a device that uses photoelectric technology and digital processing technology to convert graphics or image information into digital signals in a scanning way.

4. Light pen, also known as photoelectric pen, is a device that uses light and photocell to read special forms of data, such as barcode record sheets, into the computer system, and its appearance is similar to that of a fountain pen, so it is commonly known as light pen.

5. Voice input and output device refers to the human-computer interface device that directly inputs or outputs human voice information to the computer. Most of the information that people transmit in their daily lives is through voice, so voice input and output devices are an important development direction of human-computer interface devices.

Computer peripheral products include network cards, cameras, laptop batteries, mobile hard disk enclosures, writing tablets, split-screen devices, mouse pads, monitors, ***, mp4, etc.

Computer (sold Duan Yu computer), commonly known as computer, is a modern electronic computer for high-speed calculation, can perform numerical calculations, but also logical calculations, but also has the function of storage 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 composed of a hardware system and a software system without any software installed is called Zhongyan 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.

Inventor of the computer John von Neumann. The computer is one of the most advanced scientific and technological inventions of the 20th century, which has had an extremely important impact on human production and social activities, and has developed rapidly with strong vitality. Its application field has expanded from the initial military scientific research application to all fields of society, and has formed a huge computer industry, which has led to technological progress on a global scale, which has triggered profound social changes, and computers have spread all over ordinary schools, enterprises, and institutions, and have entered the homes of ordinary people, becoming an indispensable tool in the information society.

Commonly used equipment for computers are keyboards, mice, scanners and other input devices; Output devices such as monitors, printers, etc.; Network devices such as network cards, hubs, and routers.

Computer (computer), commonly known as computer, is a modern electronic computer machine used for high-speed computing, which can perform numerical and 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 at high speed.

A computer is composed of two parts: a hardware system and a software system.

1) Hardware system.

Power supply is an indispensable power supply equipment in the computer, which directly affects the stability of other equipment, and then affects the stability of the whole machine.

MotherboardThe motherboard is a platform for the various parts of the computer to work, which closely connects the various parts of the computer together, and each component transmits data through the motherboard.

CPUCPU is the processor, which is the computing core and control core of a computer.

Memory, also known as internal memory or random access memory (RAM), is divided into DDR memory and SDRAM memory.

Hard disk hard disk belongs to external memory, mechanical hard disk is made of metal magnetic sheet, and the magnetic sheet has a memory function, so the data stored on the magnetic sheet, whether it is turned on or off, will not be lost.

Sound cardSound card is an indispensable hardware device for the composition of multi-** computer, which converts the sound digital signal in the computer into an analog signal and sends it to the speaker to emit sound.

Graphics cardThe graphics card works with the display to output graphic text, converts and drives the display information required by the computer system, and controls the correct display of the display.

The network card network card is a network component working at the data link layer, which is the interface connecting the computer and the transmission medium in the local area network, and acts as a bridge between the computer and the network cable, and it is one of the important devices used to establish the local area network and connect to the Internet.

Modem.

The English name is "modem", that is, modem, there are built-in and external, wired and wireless.

Optical drive computers are used to read and write the contents of optical discs, and they are also a common part of desktop and notebook portable computers.

The function of the monitor is to display the results of the computer's processing.

The keyboard is the main manual input device, which is used to input and manipulate words and numbers into the computer.

2) Software system.

Refers to the programs organized to facilitate the use of computers and improve the efficiency of use, as well as the relevant documents used for development, use, and maintenance. Software systems can be divided into two categories: system software and application software.

3.Peculiarity. The calculation speed is fast, the calculation accuracy is high, the logic operation ability is strong, the storage capacity is large, and the degree of automation is high.

Enter the device.

The input device is a device that injects information into the computer, and the commonly used input devices are:

1) The keyboard --- the most basic device for people to input information into the computer;

2) mouse --- a cursor pointing device;

3) Touch screen --- a coordinate positioning device, which is often used in public inquiry systems.

Output device. The output device is a device that directly provides the results of computer operation to people, and the commonly used output devices are:

1) The monitor --- the main output device of the computer, which together with the keyboard constitutes the most basic human-computer dialogue environment;

2) Printer--- printer provides users with a hard copy of computer information.

Commonly used printers are: percussion, inkjet, and laser printers.
