The Domain Name System (DNS) is a critical component of the internet, allowing users to access websites and other online resources by using simple names rather than long strings of numbers. Let's go deeper and learn more about DNS.

What is DNS?

The Domain Name System (DNS) is a server-based network that converts human-readable domain names into machine-readable numerical addresses. It is a necessary component of the internet because it allows users to access websites and other online resources by using simple names rather than long strings of numbers.

Let's say you have a burning question that you'd like Google to answer. When you enter "www.google.com" into your web browser, your computer sends a request to a DNS server, which then converts the domain name into an IP address (e.g., 192.158.1.38). The DNS server responds with the correct IP address, and your computer can then request the webpage from the web server associated with that address.

DNS works on any internet-connected device, including computers, smartphones, tablets, and smart TVs. When you visit a website or other online resource, your device sends a request to a DNS server, which converts the domain name into an IP address.
