WebCyclic Redundancy Check (CRC) is a way of identifying unintended alterations or errors in a communication system. CRC employs the Generator Polynomial, which is present on both the transmitter and recipient sides. An example generator polynomial is in the form of x5+x3 + x + 1. This generator polynomial represents key 101011. WebCRC is a hash function based on binary division. A sequence of redundant bits (called CRC bits) are appended to the end of the data block so that the resulting block is exactly divisible by a second, predetermined binary number. At the receiver's end, the incoming message is divided by this number.
