WebThe checksum computation needs to ensure the 16-bit alignment of the data being summed. If a segment contains an odd number of header and text octets, alignment can be achieved by padding the last octet with zeros on its right to form a 16-bit word for checksum purposes. The pad is not transmitted as part of the segment. WebDiscover the benefits of a CRC check. We answer the questions: what is a cyclic redundancy check and how does CRC work? ...
