Dictionary of Computers - output device

Electronic output devices can be mechanical, audio, or visual. Mechanical outputs include motors, solenoids, and other electromagnetic devices. Audio outputs include buzzers, loudspeakers, piezo transducers, and ultrasonic transmitters. Mechanical and audio outputs tend to have a higher power demand than other output devices. Visual outputs include lamps, LEDs (light-emitting diodes), and infrared transmitters.

The most common output devices are the VDU (visual display unit, or screen) and the printer. Other output devices include graph plotters, speech synthesizers, and COM (computer output on microfilm/microfiche).
