WebError detection using checksum method involves the following steps- Step-01: At sender side, If m bit checksum is used, the data unit to be transmitted is divided into segments of m bits. All the m bit segments are added. The result of the sum is then complemented using 1’s complement arithmetic. The value so obtained is called as checksum.
