Today, I will talk to you about what equipment is generally used for the input and output of microcomputers. Many people may not know much about it. In order to let everyone know more, Xiaobian summarized the following contents for everyone. I hope everyone can gain something according to this article.

Generally use "keyboard and display" as a microcomputer necessary input and output equipment; input equipment is to input data and information to the computer equipment; output equipment is the calculation or processing results or intermediate results in various forms that people can recognize, such as numbers, symbols, letters, etc.

General use of "keyboard and display" as a microcomputer necessary input and output equipment.

Input/output device (IO device) is one of the key external devices of data processing system, which can be used interactively with computer itself. Such as: keyboard, tablet, microphone, audio, display, etc. Therefore, input and output devices play a role in the connection between man and machine.

input device

Input equipment is a device that inputs data and information to a computer, a bridge between a computer and users or other devices, and one of the main devices for information exchange between users and computer systems. The task of the input device is to transfer data, instructions, and certain identification information to the computer. Keyboard, mouse, camera, scanner, light pen, handwriting tablet, joystick, voice input device, etc. are all input devices, which are devices for human or external interaction with computers, used to input raw data and programs for processing these data into computers.

Computers can receive a variety of data, both numerical data and various non-numerical data, such as graphics, images, sounds, etc. can be input to the computer through different types of input devices for storage, processing and output. Computer input devices can be divided into the following categories according to their functions:

● Character input device: keyboard;

● Optical reading equipment: optical mark reader, optical character reader;

Graphic input devices: mouse, joystick, light pen;

● Image input equipment: digital camera, scanner, fax machine;

● Analog input equipment: speech analog-to-digital conversion recognition system.

(e.g., photoelectric tape reader, card reader, optical character reader, magnetic tape input equipment, Chinese character input equipment, mouse, etc.) to transfer data, programs, and control information into a computer.

output device

Output device is to calculate or process the results or intermediate results in various forms that people can recognize, such as numbers, symbols, letters, etc., so the input and output device plays a role in the connection between people and machines. Common displays, printers, plotters, image output systems, voice output systems, magnetic recording equipment and so on.

Display is an essential computer graphics output device, its role is to convert digital signals into optical signals, so that text and graphics displayed on the screen; printer is also a PC on the main output device, it programs, data, characters and graphics printed on paper.

Console typewriters, light pens, displays, etc. can be used as input or output devices.

Input/output devices (I/O) play a role in the connection between people and computers, equipment and computers, computers and computers.

After reading the above, do you have any further understanding of the necessary input and output equipment for microcomputers? If you still want to know more knowledge or related content, please pay attention to the industry information channel, thank you for your support.
