CHECKSUM:

checksum is an error checking technique. It involves calculating a value based on the data being transmitted or stored, and then comparing this value at the receiving end to verify if the data has been transmitted or stored accurately. If there’s a discrepancy between the calculated checksum and the received checksum, it indicates that errors may have occurred during transmission or storage. Checksums are commonly used in network protocols, file transfers, and data storage systems to ensure data integrity and reliability.
