What is the function of the CRC value that is found in the FCS field of a frame?
- to verify the integrity of the received frame
- to verify the physical address in the frame
- to verify the logical address in the frame
- to compute the checksum header for the data field in the frame
The CRC value in the FCS field of the received frame is compared to the computed CRC value of that frame, in order to verify the integrity of the frame. If the two values do not match, then the frame is discarded.
