DNS (Domain Name System) – Explained , Types of Domain Name Servers | How DNS works | TechTerms

Learn about DNS, DNS Server or DNS name server, DNS lookup, what is dns server and how it works, how DNS server or Domain Name System works. DNS or Domain Name System translates domain names to their IP addresses so that browsers can load the requested website. Servers are computers storing HTML files, images, sounds, videos or any other file types. Servers that work together to provide IP address of the requested website to the web browser are called DNS servers.

DNS resolver connects the web browser of our computer to the DNS name servers. There are 13 sets of root name servers, logically named as Letter.root-servers.net, where Letter ranges from ‘a’ to ‘m’, and are operated by 12 different organizations. Each set has a number of servers placed around the world. TLD name server stores the information of all domain names sharing a common domain extension. Authoritative name server is the last server in the Domain Name System. It stores the IP address of the requested website

When we purchase a domain name from a registrar, Registry updates the authoritative name server for the purchased domain in the TLD name server. So, when TLD name server receives a DNS query, it forwards DNS resolver to the correct authoritative name server. DNS servers eliminate the need for humans to memorize these complex IP addresses. The only thing we need to memorize is the domain names which are easier to remember. #TechTerms

    You’re awesome! I understood the concept a bit but you don’t really know if you understand something well until you have to explain it to someone else. I think I’ll be better at explaining it after watching this. Thank you!



  38. rakavan kumar on January 27, 2021 at 2:39 am

    could you pls say the name of the app or software you r using??????



  42. Coding 101 on January 27, 2021 at 2:47 am

    That’s great thanks, clears things up a bit. a video on the different record types would be cool.Thanks for the video. As well as setting up DNS for one’s own websites or something practical. DNS is quite important. I don’t quite understand how large companies with their email servers and all set up DNS for their internal network or all their sites. it’s good to know to know how thing work.

    Which layer does DNS work



  48. yuval158 on January 27, 2021 at 2:54 am

    I think the real question is, since when does the monitor of the laptop need support to keep it of the table?

    Or is that a tablet with a stand and a keyboard?



  49. MaxApex_Tutorials on January 27, 2021 at 2:54 am

    Very good. Explained the DNS very well
