Topic: Computer Networks
Which of the following is true?
- A. Both Parity and Cyclic Redundancy Check are error correcting codes
- B. Both Parity and Low Density Parity Check Code are error correcting codes
- C. Both Reed-Solomon code and Low Density Parity Check Code are error correcting codes
- D. Both Cyclic Redundancy Check and Low Density Parity Check Code are error correcting codes
Answer: C. Both Reed-Solomon code and Low Density Parity Check Code are error correcting codes
Explanation: Simple Parity and basic Cyclic Redundancy Check (CRC) are primarily error-detecting codes. Reed-Solomon (RS) codes and Low Density Parity Check (LDPC) codes are explicitly designed as Forward Error Correction (FEC) codes capable of correcting errors.
