aka How DNS works
The process involves fundamental components like the browser, your computerโs operating system, your internet service provider (ISP), the server where you host the site and the services running on that server.

When you type a domain name into a web browser, the browser needs to resolve the domain name to an IP address. The IP address is what is used to identify a specific server on the internet.

The DNS resolver is responsible for resolving domain names to IP addresses. It takes the request from your browser and sends a query to a DNS root name server. The root name server is the top of the hierarchy in the domain name system and is responsible for pointing the resolver in the right direction.

The root name server responds to the resolver with the address of the top-level domain (TLD) name server, which is responsible for the .com TLD in this case. The TLD name server is responsible for managing the domains that are part of that TLD.

The resolver then sends a request to the .com TLD name server for the IP address of the domain you requested, google.com

The browser receives the IP address from the resolver and uses it to establish a connection to the server hosting the website. The server then sends the HTML, CSS, and JavaScript that make up the website to the browser, which renders the website for you to view.
