Output Devices And Their Uses
Muhtasari
Once a computer has finished processing, it has to communicate the result, to a person or to a machine. The screen you are reading, the printer in the office, the projector in a lecture hall and the motor that opens a car-park barrier are all output devices, each turning the computer's digital signals into something useful in the real world. Choosing the right one decides whether a document looks crisp, a presentation reaches a whole hall, or a control system actually moves a valve.
In this lesson you will meet the output devices the Cambridge syllabus requires: monitors, touch screens (as output), multimedia projectors, laser, inkjet and dot matrix printers, plotters, 3D printers, speakers and actuators. You will learn how each works, where it is used, and how to weigh quality, speed, cost and purpose so you can justify the best device for any situation.
