What are two reasons for physical layer protocols to use frame encoding techniques? (Choose two.)

  • to reduce the number of collisions on the media
  • to distinguish data from control information
  • to provide better media error correction
  • to identify where the frame starts and ends
  • to increase the media throughput
    Explanation:
    An encoding technique converts a stream of data bits in a predefined code that can be recognized by both the transmitter and the receiver. Using predefined patterns helps to differentiate data bits from control bits and provide better media error detection.
