Peripheral device

Such devices make up the peripheral equipment of modern digital computer systems. Peripherals are commonly divided into three kinds: input devices, output devices, and storage devices which partake of the characteristics of the first two.

An input device converts incoming data and instructions into a pattern of electrical signals in binary code that are comprehensible to a digital computer. An output device reverses the process, translating the digitized signals into a form intelligible to the user. At one time punched-card and paper-tape readers were extensively used for inputting, but these have now been supplanted by more efficient devices. Input devices include typewriter-like keyboards; handheld devices such as the mouse , trackball, joystick, trackpad, and special pen with pressure-sensitive pad; microphones, webcams, and digital cameras.

They also include sensors that provide information about their environment— temperature , pressure , and so forth—to a computer. Another direct-entry mechanism is the optical laser scanner e. Output equipment includes video display terminals , ink-jet and laser printers, loudspeakers, headphones, and devices such as flow valves that control machinery, often in response to computer processing of sensor input data.

A bus also known as a port can be either serial or parallel , depending on whether the data path carries one bit at a time serial or many at once parallel.

Serial connections, which use relatively few wires, are generally simpler than parallel connections. Universal serial bus USB is a common serial bus. Peripheral device Article Media Additional Info.
