Did you know?

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 often used to verify data integrity but are not relied upon to verify data authenticity. The procedure which generates this checksum is called a checksum function or checksum … WebSep 2, 2024 · At the Sender side, the data is divided into equal subunits of n bit length by the checksum generator.
