Data link protocols almost always put the CRC in a trailer rather than in a header. Why? ..

Answer / cade bryant

It is more efficient. Only one pass needs to be made over the packet as it computes the CRC while scanning the packet, and then outputs it at the end (trailer). If the CRC were in the header, then two passes would be necessary - one to compute the CRC, and one more to append it to the front of the packet.
