A DNS Server, or Domain Name System Server, is a crucial component of the internet that translates human-friendly domain names like www.example.com into IP addresses like 192.0.2.1. This process allows users to access websites without needing to remember complex numerical addresses. When you enter a website's URL in your browser, the DNS Server acts like a phone book, helping to locate the server hosting the website. By efficiently managing these translations, DNS Servers ensure that internet navigation is seamless and user-friendly, making them essential for the functionality of the web.
