ARP (Address resolution Protocol)converts IP address of
Destination to physical address by broadcasting in Lan.
The host whose ip address matches replies his physical
address so data transfer can occur in datalink layer
example:
10.43.5.2->ARP-What is physical address of 10.43.5.3?(to
all in LAN)
10.43.5.3 -> it is AB:56:89:67:43:78 (to 10.43.5.2)
RARP(Reverse ARP) converts Physical address of Source to
IP address.
It is used by machine to know what is my IP address? it
broadcast RARP to all in LAN(Like do you know my IP) The
RARP server replies that this is your IP
AA:BB:CC:DD:EE:FF:GG->What is my IP address?(to all in LAN)
RARP server -> It is 1.2.4.5 (to AA:BB:CC:DD:EE:FF:GG)
