The transmitting terminal computes a numeric value representative of the number of marking bits in the associated block of data and sends that value to the receiver, where the number is recomputed to compare against the block as received. Depending on the number of bits in the CRC numeric value the error trapping efficiency ranges from about 97 % at CRC-6 to 99.997% at CRC-32. Values of CRC-8 and CRC-16 are adequate for most data message block sizes, while CRC-32 is needed mainly for very long blocks of tens of thousands of characters.
