Chapter 9: Input-Output Devices

An input device is essentially a piece of hardware component used to provide data and control signals to an information processing system such as computer or information device. Common inputs devices on modern computers include keyboards, mouse and touch screen which are used to enter commands and data directly. Other examples of input devices include scanners, digital cameras, joysticks and microphones. An output device is any hardware component that use received data from a computer to perform a task. The data received by the output device can be text, graphic, tactile, audio or video. Three most commonly used output devices are a printer, a monitor and speakers.

Inputs are the signals or data received by the system and outputs are the signals or data sent from it. For instance, a keyboard or computer mouse is an input device for a computer, while monitors and printers are output devices. Devices for communication between computers, such as modems and network cards , typically perform both input and output operations. The designation of a device as either input or output depends on perspective. Mice and keyboards take physical movements that the human user outputs and convert them into input signals that a computer can understand; the output from these devices is the computer's input.

From Hardware to Software pp Cite as. Such devices convert between the external means of recording information required by the user, such as punched holes or printed characters, and the internal means of storing information inside the computer, such as patterns of electric signals.
