Web26 jun. 2024 · For error detection, the sender needs to send some additional bits along with the data bits. The receiver performs necessary checks based upon the additional redundant bits. If it finds that the data is free from errors, it removes the redundant bits before passing the message to the upper layers. WebChecksum: The data is split into k segments of m bits each in the checksum error detection technique. To get the total, the segments are summed at the sender’s end using 1’s complement arithmetic. To obtain the checksum, a complement of the sum is taken. The checksum segment is sent with the data segments.
