ARP (Address Resolution Protocol) is used to determine the MAC address of a device when the IP address is known. It broadcasts a request on the local network asking the device with that IP address to identify itself and provide its MAC address. DHCP (Dynamic Host Configuration Protocol) is used to assign IP addresses to devices on a network. TCP (Transmission Control Protocol) is responsible for ensuring reliable data transmission between devices. DNS (Domain Name System) is used to translate domain names into IP addresses.
