What does DNS stand for?

DNS stands for Domain Name System. This system is essential for translating user-friendly domain names, such as www.example.com, into numerical IP addresses that computers use to identify each other on the network. The Domain Name System acts like an address book for the internet, enabling users to access websites using easy-to-remember names rather than having to memorize complex numerical strings.

This system is hierarchical and distributed, meaning that it is structured in levels and can be managed across various servers worldwide, ensuring the robustness and efficiency of web navigation. Understanding DNS is fundamental for IT specialists, as it plays a crucial role in networking, website hosting, and internet infrastructure.
