What does DNS stand for in networking?

The correct answer, Domain Name System, reflects the fundamental role DNS plays in networking. DNS is the system that translates human-friendly domain names, like www.example.com, into IP addresses, which are used by computers to identify each other on the network. This process is crucial because it allows users to access websites using easy-to-remember names instead of having to remember numerical IP addresses.

The name signifies its function: it organizes the various domain names in a hierarchical structure, serving as a directory for the internet. This system enhances the usability of the internet and enables efficient routing of traffic based on the requests made by these names.

In contrast, other options do not accurately represent the term. For instance, while "Data Network System" and "Distributed Network Service" might suggest certain networking concepts, they do not define the specific and critical role that DNS plays in facilitating the translation of domain names and ensuring that internet services are accessible. "Dynamic Network Solution" could imply something related to network configurations or management but misses the specific function and definition attributed to DNS in networking.
