    Parity and Checksums
    Basic error detection relies on mathematical redundancy, such as parity bits or cyclical redundancy checks (CRC). While effective for single-bit errors during transmission, these methods are notoriously poor at detecting semantic inversions, where data is physically correct but contextually reversed (e.g., inputting 'True' when 'False' was intended) [7].
