What is hamming code in digital communication?

Hamming code is an error-correcting code used in digital communication to detect and correct single-bit errors in transmitted data. Developed by Richard Hamming, it adds redundancy bits to the original data, allowing the receiver to identify and fix errors without needing a retransmission. The code uses a specific arrangement of parity bits, which are calculated based on the data bits, to ensure that any single-bit error can be pinpointed and corrected. This makes Hamming code particularly useful in reliable data transmission systems.
