What does the acronym DNS stand for?

The acronym DNS stands for Domain Name System. This system plays a critical role in how we interact with the internet by translating user-friendly domain names (like www.example.com) into IP addresses that computers use to identify each other on the network. The Domain Name System serves as the phonebook of the internet, allowing users to access websites using easy-to-remember names instead of numeric IP addresses.

This system is essential for the functionality of various internet services, enabling users to efficiently navigate the web. It supports mechanisms such as caching and redundancy, ensuring faster responses and reliability. Understanding DNS is crucial for anyone involved in IT support since issues with DNS can lead to connectivity problems that can be challenging to troubleshoot. The other options do not accurately define DNS, focusing instead on alternative interpretations or aspects of network management that are not directly related to the established meaning of the DNS acronym.
