Types Of Peripheral Devices - Input And Output
Akopọ
Every interaction you have with a digital device relies on peripheral hardware. The keyboard you type on, the screen that displays your work, and the printer that produces a hard copy are all peripherals, and choosing the right one for a task is a core ICT skill.
This topic covers the full range of input and output peripherals named in the Edexcel specification. You will learn how each device works, when it is the best choice, and how to compare alternatives in exam-style scenarios where selecting the right peripheral for a given need earns full marks.
