Input device
Input device is a device that inputs data and information to the computer. It is a bridge between the computer and the user or other devices, and between the user and the computer system. One of the main devices for information exchange. The task of the input device is to transmit data, instructions and certain sign information to the computer. Keyboards, mice, cameras, scanners, light pens, handwriting input tablets, joysticks, voice input devices, etc. are all input devices (Input Device). They are a device for humans or external devices to interact with computers. They are used to convert raw data to Programs that process this data are fed into the computer.
Computers can receive a variety of data, which can be numerical data or various non-numeric data, such as graphics, images, sounds, etc., through different types of input devices Input into the computer for storage, processing and output.
Output device
The output device (Output Device) is the terminal device of the computer hardware system, used to receive computer data output display, printing, sound, and control peripheral devices Operation etc. It also expresses various calculation result data or information in the form of numbers, characters, images, sounds, etc. Common output devices include monitors, printers, plotters, image output systems, voice output systems, magnetic recording devices, etc.
