ARP (Address Resolution Protocol) is used by a host on a network to find the MAC address of another device based on its IP address. The host sends an ARP request packet containing the IP address of the device it wants to communicate with, and the device responds with its MAC address. DNS (Domain Name System) is used to resolve domain names to IP addresses, while TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are transport layer protocols used for reliable and unreliable data transfer respectively.
