Explanation:
Detailed explanation-1: -Copied! Hamming(7, 4) is a single-error correcting code that uses a 7-bit codeword to transmit four bits of data. The sender computes three parity bits for each 4-bit data word, assembles the data and parity bits into a 7-bit codeword, and transmits this codeword.
Detailed explanation-2: -Therefore, Hamming encoding with 4 data bits and 3 parity bits for a total of 7 total bits is given as Hamming(7, 4). Standard Hamming code can only detect and correct a single-bit error. If two bits are in error, it is possible that the two errors will look like a single-bit error.
