Show answer & explanation
Basis of classification: Peripheral devices are classified by the direction of data flow between the user/computer environment and the computer system.
Input devices: These send data or instructions to the computer. Examples include keyboard, mouse, scanner, microphone, and joystick.
Output devices: These present processed information from the computer to the user. Examples include monitor, printer, speaker, and plotter.
Mixed devices: These perform both input and output roles. A touch screen displays output and also accepts touch input. A headset can output sound through earphones and input sound through a microphone.
Summary: Input means user/device to computer, output means computer to user/device, and mixed devices support both directions.
