Cyclic redundancy checking (CRC)

Cyclic redundancy checking (CRC)

An error-detection technique consisting of a test performed on each block or frame of data by both sending and receiving modems. The sending modem inserts the results of its tests in each data block in the form of a CRC code. The receiving modem compares its results with the received CRC code and responds with either a positive or negative acknowledgment.
