ARP (Address Resolution Protocol) is the protocol that bridges Layer 2 and Layer 3 of the OSI model, which in the typical TCP/IP stack is effectively gluing together the Ethernet and Internet Protocol layers.

By extension, an ARP table is simply the method for storing the information discovered through ARP.
