What is the primary function of the program named 'named' in a Linux server?

The program 'named' is an implementation of the Domain Name System (DNS) server, which primarily serves the function of hostname resolution. It translates human-readable domain names into IP addresses that computers use to communicate with each other over the network. When a user enters a URL in their web browser, named helps the system find the correct server hosting the desired website by resolving the domain name into its corresponding IP address.

Hostname resolution is crucial in network communication, as it allows users to access websites and services using easy-to-remember domain names instead of numerical IP addresses. This process involves looking up names in a DNS database and providing the corresponding IP address to the requesting system, which is precisely what 'named' is designed to do.

While other functions listed may be important in a server environment, such as file storage management, database management, and network configuration, they do not relate specifically to the primary role of 'named.' Instead, their functions pertain to different aspects of server management and operation.
