ARP (Address Resolution Protocol) is a communication protocol used to map an IP address to a physical machine's MAC address in a local network.
ARP Definition: ARP (Address Resolution Protocol) is a communication protocol used to map an IP address to a physical machine's MAC address in a local network.
Address Resolution Protocol (ARP) is a network protocol used to map an IP address to a MAC address on a local network. When a device needs to communicate with another device on the same network, ARP is used to discover the MAC address associated with the destination IP address. This mapping information is then stored in the ARP cache to facilitate efficient data transmission within the network. ARP helps devices identify and communicate with each other at the data link layer of the OSI model.
