(1) Pertaining to a device whose parts can perform an input process and an output process at the same time (I). (2) Pertaining to a functional unit or channel involved in an input process, output process, or both, concurrently or not, and to the data involved in such a process. (3) Pertaining to input, output, or both (D). (4) An operation or device that allows input and output. IEEE. An organization of engineers and technical professionals that promotes the development and application of electronic technology and allied sciences. Hardware product that is mounted in a cabinet. For example, any director or switch shipped within a cabinet is an integrated product. (1) A shared boundary between two functional units, defined by functional, signal, or other characteristics. The concept includes the specification of the connection of two devices having different functions (T). (2) Hardware, software, or both, that link systems, programs, or devices (D).
