Question

what is meant by input and output? give an example ​

Answer 1

Answer:

An input device sends information to a computer system for processing, and an output device reproduces or displays the results of that processing.

For example, as you can see in the top half of the image, a keyboard sends electrical signals, which are received by the computer as input.

Answer 2

An input is data that a computer receives. An output is data that a computer sends. Computers only work with digital information. Any input that a computer receives must be digitised. Often data has to be converted back to an analogue format when it's output, for example the sound from a computer's speakers.
