Output device

An output device is computer hardware that presents or transmits information produced by a computer, converting digital data into forms people or other systems can perceive or use.

Computer display: A screen that presents computer-generated images and text as visible light. Displays turn digital image data into visual output.
Computer hardware: The physical components of a computer system. Output devices are one class of physical computer components.
Braille display: A refreshable device that presents digital text as tactile Braille characters. It makes computer output accessible through touch.
Input-output device: Hardware that both sends information to a computer and presents or transmits information from it. Bidirectional devices combine output functions with input functions.
Printer: A machine that produces a physical copy of digital text or images on a medium such as paper. Printers convert document data into tangible marks.
Input device: Hardware that sends data or control signals into a computer. Input devices carry information in the opposite direction.
Projector: An optical device that casts an image onto a separate surface, usually a screen or wall. Projectors enlarge computer visuals for shared viewing.
Storage device: Hardware that records and retrieves digital data for later use. Storage retains data rather than primarily presenting it.
Computer speaker: A transducer that converts electrical audio signals into sound waves. Speakers render computer audio as sound.
Peripheral: A device connected to a computer that extends its functions beyond core processing and memory. Many output devices connect as peripherals rather than internal components.
