Scanner is an example of an input device.
In computing, an input device is a piece of computer hardware equipment used to provide data and control signals to an information processing system such as a computer or information appliance. Examples of input devices include keyboards, mouse, scanners, digital cameras and joysticks.
The computer mouse and scanner fall under the input device category. As the name suggests, input devices are used to send information to the computer. A mouse is used to input the movements of a cursor, while a scanner is used to input physical media into digital format.
A scanner is a device that captures images from photographic prints, posters, magazine pages, and similar sources for computer editing and display. Scanners come in hand-held, feed-in, and flatbed types and for scanning black-and-white only, or color.
