Hamming Code Hamming code is an improvement over the other parity systems, this approach enable us to detect one bit error that might get introduced during transmission in every byte of information, However, this is done at the cost of increased data size due to introduction of multiple parity bits. Calculating the Hamming Code   The Hamming method make use of multiple parity bits at bit positions 1,2,4,8,.......... Whereas VRC/HRC method was able to detect a single bit error in a block of data, the help of Hamming  code enable us to detect and correct single bit error in every byte that is being sent or received. The following step helps in creating the Hamming code word: 1st of all mark all bit positions (1,
