Data Commincations: Error Detection and Correction Help understanding Excerpt: Text reads: "The Internet checksum provides greater error-detection capability than a parity bit or two-dimensional parity scheme but is considerably less effective than the cyclic redundancy check (CRC), discussed next. The primary reason for its adoption in Internet protocols is efficiency. Most of these protocols are implemented in software and the Internet checksum, involving simple addition and comparison operations, causes very little overhead. It is assumed that at the lower link...

Q1 Error detection/correction Can these schemes correct bit errors: Internet checksums, two-dimendional parity, cyclic redundancy check (CRC) A. Yes, No, No B. No, Yes, Yes c. No, Yes, No D. No, No, Yes E. Ho, hum, ha Q2 CRC vs Internet checksums Which of these is not true? A. CRC's are commonly used at the link layer B. CRC's can detect any bit error of up to r bits with an r-bit EDC. c. CRC's are more resilient to bursty...
