与二维奇偶校验相比，CRC有什么优势吗？

Answer 1

with CRC, you can detect "burst" errors, that is any sequence of errors. CRC uses fewer bits. with CRC you can correct one bit errors.

2 dim parity you can detect 1, 2 and 3 bit errors and sometimes 4 bit errors 4 bit errors that are not detected are ones on 4 corners (forming a rectangle)
