Hamming code

algorithm Extra, redundant bits added to stored or

transmitted data for the purposes of error detection andcorrection.

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.
