Recognition-and-flagging meaning

An error control mode in which detected errors are flagged by the receiving device, but there is no mechanism for error correction. Rather, error correction requires a human-tomachine request for retransmission. Recognition and flagging is primarily used in networks involving dumb terminals with no means of buffering or retaining information transmitted and which, therefore, are unable to retransmit errored data. Parity checking is an example of recognition and flagging. See also buffer, dumb terminal, error control, FEC, parity check, and recognition and retransmission.
