   Q1. What is the purpose of cyclic redundancy check (CRC) in error detection?

   • A) To detect single-bit errors
   • B) To detect multiple-bit errors
   • C) To detect and correct errors
   • D) To compress data

   Answer: To detect multiple-bit errors

   Explanation: CRC is used to detect multiple-bit errors by generating a checksum based on the data being transmitted and checking it at the receiver's end.
