Q4. (72, 64) SEC/DED Hamming code is a modified SEC Hamming code which can correct all single bit errors and detect double bit errors in the data. It is usually used in a memory system with 64-bit data word and 8 parity bits. Compared to that, what is the error correction and detection capabilities of a single-parity-per-byte code with the same number of data and parity bit? List the types of multiple errors that are detectable by the single-parity-per-byte code. (Hint: In single-parity-per-byte code, the 64-bit data is separated into 8 groups of 8-bit data word and one parity bit is added for each group of 8- bit data word.)
