input/output

[′in‚pu̇t ′au̇t‚pu̇t]
(computer science)
Pertaining to all equipment and activity that transfers information into or out of a computer. Abbreviated I/O.

input/output

(programming, operating system)
(I/O) Communication between a computer and its users, its storage devices, other computers (via a network) or the outside world. The devices the computer uses to do this are called "peripherals". What actually counts as I/O depends on what level of detail you are considering, e.g. communication between processors would not be considered I/O when considering a multiprocessor as a single system.

Important aspects of I/O are throughput, latency, and whether the communications is synchronous or asynchronous (using some kind of buffer).
