What are input devices?

Input devices are hardware components that allow users to enter data and commands into a computer or electronic device. Examples include keyboards, mice, touchscreens, scanners, and microphones.

What are output devices?

Output devices are hardware components that display or present information processed by a computer. Examples include monitors, printers, speakers, projectors, and headphones.

How do input devices work?

Input devices transmit data or commands to a computer by converting physical actions or signals into electronic signals that the computer can understand and process.

How do output devices work?

Output devices receive electronic signals from a computer and convert them into human-readable or perceptible forms, such as visual displays, printed documents, audio sounds, or projected images.

Why are input and output devices important?

Input devices allow users to interact with computers and provide necessary instructions and data. Output devices enable users to receive feedback, information, and results from the computer, making the interaction and communication process between humans and machines possible.
