What does DNS stand for?

The correct answer, "Domain Name System," refers to the system that translates human-friendly domain names, like www.example.com, into IP addresses that computers use to identify each other on the network. This is an essential function for the functionality of the internet, as it enables users to access websites using easily remembered names rather than numerical IP addresses.

The Domain Name System operates like a phonebook for the internet, allowing users to find the resources they need without having to remember complex numeric addresses. It plays a crucial role in the infrastructure of the web, facilitating the accessibility of websites and domain services.

In contrast, the other options do not accurately describe this critical component of internet architecture. Data Network Services, for instance, suggests a broader concept that could encompass various services beyond naming. Dynamically Named Services may imply a temporary or changing methodology related to services, which is not representative of the function of DNS. Lastly, the term Distributed Network System could pertain to a different aspect of network architecture but does not specifically signify the naming and addressing service provided by DNS. Thus, the significance and fundamental role of the Domain Name System in networking make it the correct answer.
