- ARP :
- Address Resolution Protocol
Address Resolution Protocol (ARP) is a network protocol used to map an Internet Protocol (IP) address to a physical machine address (MAC address) on a local area network. When a device wants to communicate with another device on the same network, it uses ARP to translate the IP address into a MAC address, allowing the data to be correctly routed to the intended recipient. ARP plays a crucial role in facilitating communication within networks, ensuring that data packets reach their correct destinations.
