What is the purpose of DNS (Domain Name System) in networking?
Hey Helen
DNS, short for Domain Name System, acts as the internet’s phone book, facilitating a seamless user experience online. It operates hierarchically with a distributed database system, ensuring the translation of domain names into IP addresses is done accurately and swiftly. When a user enters a domain name into a browser, the DNS servers work behind the scenes to map that name to a corresponding IP address, directing the user’s request to the correct server.
This process is pivotal for routing traffic across the internet, making it possible for users to access websites, send emails, and use other internet services using understandable domain names without needing to memorize complex numerical IP addresses.
