With this checksum, any transmission error which flips a single bit of the message, or an odd number of bits, will be detected as an incorrect checksum. However, an error that affects two bits will not be detected if those bits lie at the same position in two distinct words. See more A checksum is a small-sized block of data derived from another block of digital data for the purpose of detecting errors that may have been introduced during its transmission or storage. By themselves, checksums are … See more Parity byte or parity word The simplest checksum algorithm is the so-called longitudinal parity check, which breaks the data into "words" with a fixed number n of bits, … See more • Additive Checksums (C) theory from Barr Group • Practical Application of Cryptographic Checksums See more General topic • Algorithm • Check digit • Damm algorithm • Data rot See more WebThe checksum algorithm is: The checksum field is the 16 bit one's complement of the one's complement sum of all 16 bit words in the header.
