What is Domain Name System(DNS)?

 The Domain Name System (DNS) is an essential part of the Internet infrastructure and helps translate human-readable domain names into machine-readable IP addresses. Simply put, DNS acts as the Internet's phone book and helps users access websites by converting domain names (like www.example.com) into IP addresses (like 192.168.1.1).

At its core, DNS is a hierarchical, decentralized naming system that allows users to access the Internet using domain names instead of cumbersome IP addresses. It acts as an identity management service, converting web users into IP addresses that computers and network devices can understand. This process is essential for the smooth operation of many Internet services, including web browsing, email, and online games.

The Domain Name System is the core of the web, the backbone that converts human-readable names into machine-readable IP addresses. Its layered and decentralized structure provides clear and reliable network navigation. Understanding the DNS system is important for anyone who interacts with the Internet, whether a user, IT professional, or webmaster.
