Speakers, projectors, and printers are categorized as which type of devices?

Speakers, projectors, and printers are categorized as output devices because they are designed to present or output data that has been processed by a computer. Output devices take electronic signals from the computer and convert them into a form that is understandable to humans.

For instance, speakers convert digital audio signals into sound, allowing users to hear music or notifications. Projectors take images or video content and display it on a larger screen, enabling a group to view the same content simultaneously. Printers take information from a computer and produce a physical copy of it on paper. Each of these devices performs the function of delivering processed information in a way that can be perceived by users, which is the defining characteristic of output devices.
