The checksum is a mathematical device that checks the integrity of the data. The image has a binary number added to it, the computer performs a mathematical process on the data and compares the resulting checksum with that imported with the image, and if the two checksums agree, then the data hasn't been corrupted. A similar checksum process is generally performed when you download files from the internet, and your computer performs a checksum test on the BIOS data at bootup for the same reason.
