Short Answer:
Input and output devices are hardware components that help a computer interact with users and other systems. Input devices allow users to enter data into the computer, while output devices display or produce results based on processed data.
Examples of input devices include a keyboard, mouse, scanner, microphone, and webcam, which help in feeding data. Examples of output devices include a monitor, printer, speaker, and projector, which present information in visual, printed, or audio formats. Both types of devices are essential for user interaction and system functionality.
Detailed Explanation
Input and Output Devices
A computer system requires both input and output devices to function properly. Input devices send data to the computer, while output devices receive processed data and display results. These devices allow users to interact with the system efficiently.
