![]() ![]() ![]() All packets sent over a network connection are checked with a CRC. Nowadays CRC calculations are used in all types of communications. The CRC calculation or cyclic redundancy check was the result of this. To overcome this problem people have searched for mathematical sound mechanisms to detect multiple false bits. This simple detection mechanism works if an odd number of bits in a byte changes, but an even number of false bits in one byte will not be detected by the parity check. ![]() For serial data they came up with the solution to attach a parity bit to each sent byte. Since the beginning of computer science, people have been thinking of ways to deal with this type of problem. Whenever digital data is stored or interfaced, data corruption might occur. ![]()
