CRC

CRC stands for cyclic redundancy check

CRCs are designed to protect against common types of errors on communication channels, but are not suitable for protecting against intentional alteration of data. CRCs use a family of related algorithms rather than a single standardized one. A variety of cyclic redundancy checks have been incorporated into technical specifications. For example, many specifications, including ZIP, use a variant commonly called CRC-32.
