The checksum field in the TCP header allows the receiving node to verify whether a TCP segment has been corrupted during transmission. The checksum is calculated over the entire TCP segment, including the TCP header and data, and is included in the header of the segment. The receiving node calculates the checksum over the received segment and compares it to the checksum in the header. If there is a mismatch, the segment is assumed to be corrupted and is discarded.
