IO

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.https://www.bbc.co.uk/bitesize/topics/zf2f9j6/articles/zx8hpv4#:~:text=An%20input%20is%20data%20that,only%20work%20with%20digital%20information.&text=An%20input%20device%20is%20something,has%20information%20sent%20to%20it.
In computing, input/output (I/O, or informally io or IO) is the communication between an information processing system, such as a computer, and the outside world, possibly a human or another information processing system. Inputs are the signals or data received by the system and outputs are the signals or data sent from it. The term can also be used as part of an action; to "perform I/O" is to perform an input or output operation.https://en.wikipedia.org/wiki/Input/output
In computing, an input device is a piece of equipment used to provide data and control signals to an information processing system such as a computer or information appliance. Examples of input devices include keyboards, mouse, scanners, cameras, joysticks, and microphones.https://en.wikipedia.org/wiki/Input_device An output device is any piece of computer hardware equipment which converts information into human read able form. It can be text, graphics, tactile, audio, and video.
Some of the output devices are Visual Display Units (VDU) i.e. a Monitor, [[Printer (computing)|Printer graphic Output devices,CMP 477 Computer Graphics Module 2: Graphics Systems – Output and Input Devices Dr. S.A.
