Examples of output devices

A projector is a device that allows you to display images, videos, or other content on a large screen or surface. It works by projecting light through a lens, which magnifies and focuses the image onto the desired surface, creating a larger representation of the content being displayed.

Examples of output devices

Headphones perform a similar function as computer speakers in that they allow users to listen to audio from an electronic device. Headphones typically connect to a single device through either a wired or wireless connection. This device then transmits the audio signal through to the headphones, allowing the user to listen to the audio directly in their ears.

A plotter is a printer that interprets commands from a computer to make line drawings on paper with one or more automated pens. Unlike a regular printer, a plotter can draw continuous point-to-point lines directly from vector graphic files or commands.
