DNS (Domain Name System) is a service that translates a domain name into an IP address. It helps users access websites using easy-to-remember names instead of numeric IP addresses.
For example, when you type www.google.com, DNS finds the correct IP address of Google’s server and connects your browser to the website automatically.
In simple words, DNS is like the internet’s phone book. It converts website names into IP addresses so your browser can find the correct server.
