Remarks
A cyclic redundancy check (CRC) is an error-detecting code used to detect data corruption. When sending data, short check sum is generated based on data content and sent along with data. When receiving data, check sum is generated again and compared with sent check sum. If the two are equal, then there is no data corruption.
