What is the purpose of the FCS field in a frame?

  • to obtain the MAC address of the sending node
  • to verify the logical address of the sending node
  • to compute the CRC header for the data field
  • to determine if errors occurred in the transmission and reception

Explanation: The FCS field in a frame is used to detect any errors in the transmission and receipt of a frame. This is done by comparing the CRC value within the frame against a computed CRC value of the frame. If the two values do not match, then the frame is discarded.
