In telecommunication, a longitudinal redundancy check (LRC) or horizontal redundancy check is a form of redundancy check that is applied independently to each of a parallel group of bit streams. The data must be divided into transmission blocks, to which the additional check data is added.
The term usually applies to a single parity bit per bit stream, calculated independently of all the other bit streams (BIP-8). although it could also be used to refer to a larger Hamming code.
This "extra" LRC word at the end of a block of data is very similar to checksum and CRC.

Famous quotes containing the word check:
“The habit some writers indulge in of perpetual quotation is one it behoves lovers of good literature to protest against, for it is an insidious habit which in the end must cloud the stream of thought, or at least check spontaneity. If it be true that le style c’est l’homme, what is likely to happen if l’homme is for ever eking out his own personality with that of some other individual?”
—Dame Ethel Smyth (1858–1944)
