Hamming code is a popular error detection and error correction method in data communication.

Hamming code can only detect 2 bit error and correct a single bit error which means it is unable to correct burst errors if may occur while. Hamming code is used in Digital systems to detect and correct a single bit error in a transmitted code. It works a little bit different. When you check parity, you don' t use parity bits to count it ( you count them now). So: p1 = = 10111 = 0 ( OK) p2. Detecting and correcting errors.
