The document discusses various input and output devices used in computing. Monitors display the graphical user interface and show running processes, while mice and keyboards allow users to input information through movement and keystrokes. Printers provide output and come in laser or inkjet varieties for different printing needs. Optical drives read and sometimes write data to discs, and hard disk drives store operating systems, applications, and data on internal storage. Other input devices include touchpads, trackballs, video digitizers, and joysticks, while outputs include speakers, graph plotters, and sound cards.
