Domain Name System — translates human-readable domain names into IP addresses.

Definition
The Domain Name System (DNS) is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network. It translates domain names, which are easy for humans to remember, into the numerical IP addresses needed for locating and identifying computer services and devices. DNS functions like the internet's phonebook, resolving queries through a distributed network of authoritative name servers.
Example
“When you enter 'www.google.com' in your browser, a DNS server resolves it to Google's IP address so your browser can connect.”
