To ensure data integrity, it's wise to frequently calculate file checksums. The C program in Listing 1 calculates the checksum of a file using a 16-bit CRC (cyclic redundancy check). The program ...

Hence, the checksum for 0101011 is therefore, equal to 4. I think I am wrong though, because it is entirely possible for the most significant bit to change from 0 to 1, and the least significant bit ...
