ADDRESS RESOLUTION WITH TABLE LOOKUP:
Resolution needs data structure that has information about address binding. A distinct address-binding table is used for every physical network. The major advantage of the table lookup function is generality; a table can save the address bindings for an arbitrary set of devices.
