Question

What the difference between CRC and checksum?

Answer 1

Check out HowStuffWorks for a good description of both and how they differ.

From the page:

Cyclic Redundancy Check (CRC)

CRCs are similar in concept to checksums, but they use polynomial division to determine the value of the CRC

More info is given at the link above including an example of how a checksum is calculated.
