Today, Hamming code really refers to a specific (7,4) code Richard W. Hamming introduced in 1950. The code stemmed from his work as a theorist at Bell Telephone laboratories in the 1940s. Hamming invented the code in 1950 to provide an error-correcting code to reduce the wasting of time and valuable computer resources. Hamming Code adds three additional check bits to every four data bits of the message. Hamming's (7,4) algorithm can correct any single-bit error, or detect all single-bit and two-bit errors. In other words, the Hamming distance between the transmitted and received words must be no...
