Start by understanding how a 2D parity check works for a 64-bit array arranged in an 8×8 grid. Recall that parity bits are used to detect errors in data transmission.

Consider how the arrangement of parity bits in rows and columns can help detect and correct errors. Think about the concept of Hamming distance and how it relates to error detection and correction.

Analyze the Single Error Correction and Double Error Detection (SEC-DED) capability of the 2D parity check. Calculate the minimum Hamming distance required for SEC-DED and compare it with the Hamming distance provided by the 2D parity check scheme.
