output device
)
The component parts of the microcomputer: the system unit contains the hub of the system, including the central processing unit (CPU), information on all of the computer's peripheral devices, and often a fixed disk drive. The monitor (or visual display unit) displays text and graphics, the keyboard and mouse are used to input data, and the floppy disk and CD-ROM drives read data stored on disks.
Any device for displaying, in a form intelligible to the user, the results of processing carried out by a computer.
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 VDT (visual display terminal) and the printer. |
