Domain Name System (DNS)
The Domain Name System (DNS) functions as the directory or "phone book" of the Internet by translating human-readable names (such as example.com) into numeric IP addresses that networking equipment requires to route packets. When a user navigates to a domain, the device initiates a DNS lookup to request the corresponding IP address from a DNS server; without DNS resolution, users would be required to memorize and manually input numeric IP addresses for every website.
