入出力
Also known as I/O, IO, I/O-unit, input-output relationship, excitation-response relation
In computing, input/output (I/O, i/o, or informally io or IO) is the communication between an information processing system, such as a computer, and the outside world, such as another computer system, peripherals, or a human operator. 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.
AI overview
Input/output (I/O) refers to how computers communicate with the outside world—receiving data and signals from external sources like other computers, devices, or people, and sending data and signals back out. It matters because without I/O, computers would have no way to interact with users or other systems, making them essentially isolated and unusable.
