In computer science and telecommunication, Hamming codes are a family of linear error-correcting codes. 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. Hamming codes are perfect codes, that is, they achiev… WebNov 23, 2024 · Construct the even parity Hamming code word for a data byte 1001101. The number (1001101) of bits is 7.
