WebbChecksum is a calculated value that is used to determine the integrity of data. Checksum serves as a unique identifier for the data (a file, a text string, or a hexadecimal string). If the data changes then so does the checksum value. This makes it easy to verify the integrity of the data. To test data integrity, the sender of the data ... WebbThe theory of checksum calculation accounts for lots of use cases and can get quite complex for those unfamiliar with its implications. Below is a simple illustration of how the checksum can be calculated for a data segment of 8 bits, separated into 2 4-bit words. The client uses the sum of all data bits to calculate the checksum value
