What does the abbreviation "DNS" stand for?

The abbreviation "DNS" stands for Domain Name System. It is a crucial component of the internet that translates human-readable domain names, like www.example.com, into IP addresses, which are used by computers to identify each other on the network. The DNS functions as a directory service for the internet, enabling users to access websites using easy-to-remember domain names rather than numeric IP addresses. This system is essential for the functioning of the internet, as it allows for the seamless navigation of online resources.

The other options may sound plausible but do not accurately describe the standardized system that DNS represents in the context of networking. Understanding this fundamental aspect of internet infrastructure is vital for administrators as they manage and configure network services effectively.
