This document summarizes different types of computer peripherals including input, output, and storage devices. Input devices take various forms of input like audio, text, video, and graphics from microphones, keyboards, scanners, webcams, and digital cameras. Output devices display or print the results of processing through monitors, printers, projectors, and speakers. Storage devices hold data electromagnetically for later retrieval, with primary storage like RAM being fast but temporary and secondary storage like hard disks being slower but permanent.
