Detailed explanation-1: -Hamming codes can detect one-bit and two-bit errors, or correct one-bit errors without detection of uncorrected errors. By contrast, the simple parity code cannot correct errors, and can detect only an odd number of bits in error.
Detailed explanation-2: -The process or method of correcting single bit errors is called “single bit error correction”. The method of detecting and correcting burst errors in the data sequence is called “Burst error correction”.
Detailed explanation-3: -In coding theory, Hamming(7, 4) is a linear error-correcting code that encodes four bits of data into seven bits by adding three parity bits. It is a member of a larger family of Hamming codes, but the term Hamming code often refers to this specific code that Richard W.
Detailed explanation-4: -Hamming Code Hamming for error correction. In this coding method, the source encodes the message by inserting redundant bits within the message. These redundant bits are extra bits that are generated and inserted at specific positions in the message itself to enable error detection and correction.
