What the difference between CRC and checksum?

Answer 1

CRC (Cyclic Redundancy Check) is a type of checksum, specifically a position dependent checksum algorithm (among others, such as Fletcher's checksum, Adler-32). As their name suggest, these detect positional changes as well, which makes them more robust - thus more widely used - than other checksum methods.
