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.
