Fascinating Fact:

Speakers and headphones output sound, and they convert digital audio data into vibrations you can hear.

In KS3 ICT, data output is about how a computer sends processed data to an output device so people can understand it. Outputs can be visual, printed, or audio, and the best choice depends on the task, the audience, and the detail needed.

  • Output device: Hardware that presents results from a computer, such as a monitor, printer, projector, or headphones.
  • Hard copy: An output you can hold, usually printed on paper, like a report or a ticket.
  • Resolution: How detailed an image or print is, often described by how many pixels or dots are used.
What does data output mean in ICT?

In ICT, data output means the computer presenting processed information in a usable form, such as showing it on a screen, printing it, or playing it as sound.

What are examples of output devices?
