Which Internet service translates human-friendly domain names (for example, example.com) into the numerical IP addresses that computers require to locate and communicate with those resources on the network?
Hypertext Transfer Protocol (HTTP)
Dynamic Host Configuration Protocol (DHCP)
Domain Name System (DNS)
Packet switching
The Domain Name System (DNS) acts like the Internet's phone book. When a user enters a domain name into a browser, DNS servers resolve that name to the corresponding IP address so the request can reach the correct host. DHCP assigns IP addresses, HTTP carries web content, and packet switching describes how data is broken into packets for transmission-none of these perform the name-to-address translation that DNS provides.
