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. WebA checksum is a value that represents the number of bits in a transmission message and is used by IT professionals to detect high-level errors within data transmissions. Prior to transmission, every piece of data or file can be assigned a checksum value after running a cryptographic hash function.
