Narrated lesson · press play
Output devices take the data a computer has processed and turn it into something we can see, hear, feel or use in the real world. In this lesson Miss Maria shows how inkjet, laser, braille and 3D printers work, compares LCD and LED screens and LCD and DLP projectors, and explains how actuators turn an electrical signal into movement.
What you'll learn in this lesson
By the end you should be able to (NSSCO Computer Studies 5.1):
