Correct Answer: The address resolution protocol (ARP) is used to associate the 32 bit IP address with the 48 bit physical address, used by a host or a router to find the physical address of another host on its network by sending a ARP query packet that includes the IP address of the receiver The reverse address resolution protocol (RARP) allows a host to discover its Internet address when it knows only its physical address
