In other words, it is a sum that checks the validity of data. Checksums are typically used to compare two sets of data to make sure they are the same. Some common applications include verifying a disk image or checking the integrity of a downloaded file. ...

A parity bit is appended to the original data bits to create an even or odd bit number; the number of bits with value one. The source then transmits this data via a link, and bits are checked and verified at the destination. ...
WebApr 6, 2001 · Checksum - Probably one of the oldest methods of ensuring that data is correct, checksums also provide a form of authentication because an invalid checksum suggests that the data has been compromised in some fashion. A checksum is determined in one of two ways. Let's say the checksum of a packet is 1 byte long. WebAnswer (1 of 4): Roland Hughes’ answer was correct as far as it went. But you need to know that a checksum is the value of some function involving all the data in something (a file, a packet, etc.). The function yields are relatively small number (in size, not necessarily in value) that changes s...
