The simplest error-detection system, the parity bit, is in fact a trivial 1-bit CRC: Jr. The device may take corrective action, such as rereading discs to correct errors caused by scratches. that generates it is occasionally used as a hash function. https://en.wikipedia.org/wiki/Cyclic_redundancy_check
