📝 Sample Questions

Q1. What is the primary purpose of a CRC in data communication?

🔹 A. Detect errors
🔹 B. Correct errors
🔹 C. Compress data
🔹 D. Encrypt data

💡 Difficulty: easy | ✅ Correct: A

Q2. If a CRC generator polynomial has degree 3, how many check bits are appended to the dataword?

🔹 A. 2
🔹 B. 3
🔹 C. 4
🔹 D. 5

💡 Difficulty: medium | ✅ Correct: B

Q3. Consider two independent errors occurring at positions 2 and 5 of a 7‑bit codeword using simple parity. Why may the syndrome be zero and what does this imply for detection?

🔹 A. The errors cancel, leaving syndrome zero; parity cannot detect even errors.
🔹 B. The syndrome will always be non‑zero for any two errors.
🔹 C. The generator polynomial forces a non‑zero remainder.
🔹 D. THE SYNDROME IS UNPREDICTABLE.

💡 Difficulty: hard | ✅ Correct: A
