This means that five randomly distributed bit failures are detectable. The polynomial is also able to detect burst-errors up to 15 bit. However, this is only true for a fixed data length. phil willis bar rescueA 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.
