If the complemented result is zero, it means the data is error-free.

These subunits also contain checksum as one of the subunits. Checksum checker divides this data unit into various subunits of equal length and adds all these subunits. The Receiver after receiving data + checksum passes it to checksum checker. This complemented sum which is called checksum is appended to the end of original data unit and is then transmitted to Receiver. These subunits are then added together using one’s complement method. This method makes the use of Checksum Generator on Sender side and Checksum Checker on Receiver side.Īt the Sender side, the data is divided into equal subunits of n bit length by the checksum generator.

Difference between Synchronous and Asynchronous TransmissionĬhecksum is the error detection method used by upper layer protocols and is considered to be more reliable than LRC, VRC and CRC.
