What is DNS? | How DNS works?

Working of DNS:

The Resolver server is basically an Internet Service Provider(ISP).

The Root server is just one of the 13 root name servers that exist today. Root servers sit at the top of the DNS hierarchy.They are scattered around the globe.

The coordination of most TLDs belongs to the Internet Corporation for Assigned Names and Numbers(ICANN). The .com TLD was one of the first created in 1985.

When a domain is purchased, the Domain registrar reserves the name and communicates to the TLD registry, Authoritative name servers(No cached values, the real deal).
