Hamming code
Extra, redundant bits added to stored or
transmitted data for the purposes of {error detection and
correction}.
Named after the mathematician {Richard Hamming}, Hamming codes
greatly improve the reliability of data, e.g. from distant
space probes, where it is impractical, because of the long
transmission delay, to correct errors by requesting
retransmission.
