WebA cyclic redundancy check ( CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents. WebA CRC or cyclic redundancy check word is often appended at the end of a long string or packet of data, prior to the error-correcting encoder. The CRC word is formed by taking all the data words and exclusive OR gate (EXOR) each word together. For example, the data sequence might be 1024 bits, organized as 64 words, each 16 bits.
