- Output devices show or produce information from a computer
- Output can be seen, heard, printed, or projected
- Choose the output device based on how the information needs to be presented
Section 1What output means
Output is information produced by a computer after processing. An output device presents that information to the user. Here's the trick: output comes out of the computer system.
Section 2Visual output
A monitor shows text, images, videos, and software screens. A projector shows the computer's display on a larger surface. In a classroom at Ardenne, a projector may be used so everyone can see a presentation.
Section 3Printed and sound output
A printer produces hard copy on paper. Speakers and headphones produce sound. Watch out: a printer is output because it produces information; it does not enter data into the computer.
Section 4Choosing output devices
Use a monitor for viewing, a printer for paper copies, speakers for sound, and a projector for large displays. Easy to mix up: headphones and speakers both output sound, but headphones are for private listening.
