Hi Friends, I am Anshul Tiwari, and welcome to our youtube channel ITkFunde.
More about this video -
Domain Name Service aka DNS is the unsung hero of networking. Without DNS it would be impossible for us to traverse through this vast jungle of the world wide web.
So let's learn what is dns in a fun way? I am sure anyone even without an I.T. background would be able to understand DNS after watching this tutorial.
We will cover dns with a layman example and then take a more detailed look into how exactly dns server works. How different domains are structured into parent-child relationships. What kind of dns queries are used to reach a device over the network.
WE HAVE ADDED USEFUL TOPICS IN OUR NETWORKING AND INFRA SERIES (LINK ABOVE).
PLEASE WATCH ALL THE VIDEOS FOR BETTER UNDERSTANDING !!
