What does DNS stand for?

DNS stands for Domain Name System. It is a hierarchical system that translates human-readable domain names, like www.example.com, into their corresponding numerical IP addresses, which are used by computers to communicate with one another over the internet. This translation process is essential for the functionality of the web, as it allows users to access websites using easy-to-remember names rather than confronting complex numerical IP addresses.

The other alternatives, while they include terms related to networking and technology, do not accurately define the role and function of DNS within the context of internet functionality. Domain Name System is the correct terminology that describes this vital service that supports users' ability to navigate the web efficiently. Understanding DNS is fundamental for anyone involved in web design or internet technologies, as it underpins how users find and connect to web resources.
