Domain Name System (DNS)
The Domain Name System (DNS) serves as the directory or "phone book" of the Internet by translating human-readable domain names, such as example.com, into the numeric IP addresses required by networked computers to route data. Without DNS resolution, users would be required to memorize and manually input numeric IP addresses to locate and communicate with network hosts.
