What is the main advantage of using checksums for error detection over a simple parity check?
Checksums can detect multiple-bit errors more effectively.
Checksums are simpler to implement.
Checksums use less overhead.
Checksums provide data encryption.
Giải thích
Checksums offer improved error detection capabilities, particularly for burst errors, compared to the basic single-bit error detection of parity checks.
