What is the primary function of a DNS server?

The primary function of a DNS (Domain Name System) server is to translate domain names into IP addresses. When users enter a web address into their browser, the DNS server converts that human-readable domain name, such as www.example.com, into a numerical IP address that computers use to identify each other on the network. This process allows users to access websites and services without needing to remember complex numeric addresses.

While translating MAC addresses to IP addresses might relate to networking, it is not the role of a DNS server. DNS focuses specifically on resolving domain names. Additionally, managing user access, storing log files, and encrypting data are functions typically associated with other network services and security protocols, rather than the primary role of a DNS server. Therefore, the correct choice emphasizes the essential task of DNS in facilitating web navigation and connectivity by resolving domain names to their corresponding IP addresses.
