Cyclic Redundancy Check

An integrity checking process for block data.

A Cyclic Redundancy Check character is generated at the transmission end with the value based on the hexadecimal value of the number of ones in the data block.
The transmitting device calculates the value and appends it to the data block.
The receiving end makes the same calculation and compares its results with the added character.
If there is a difference, the recipient requests retransmission.
