How Computers Work: Input and Output How Computers Work: Input and Output The central processing unit is the unseen part of a computer system, and users are only dimly aware of it. But users are very much aware of the input and output associated with the computer. They submit input data to the computer to get processed information, the output. Sometimes the output is an instant reaction to the input.

How Computers Work: Input and Output Terminals. A screen may be the monitor of a self-contained personal computer, or it may be part of a terminal that is one of many terminals attached to a large computer. A terminal consists of an input device, an output device, and a communications link to the main computer. Most commonly, a terminal has a keyboard for an input device and a screen for an output device, although there are many variations on this theme.

The Definition of Input Devices Input devices are hardware components that enable users to interact with a computer. Without input devices, you would not be able to feed instructions to a computer. The most common input devices in modern computers are the mouse (or pointing device), the keyboard, the scanner, the webcam and the microphone. Another input device, serving a niche purpose, is the joystick, used in gaming.
