How Does The World Wide Web Works?

It's a little complex but I'll try to simplify it as much as I can:

1. You open your browser or application (that gets information from the internet and is more than likely using HTTP protocol for the communication as it is the standard these days)
2. You navigate to the page you want
3. Your device first tries to convert the destination's name (FQDN) to an address it can actually understand (IP)
4. The device sends a connection request (TCP) to the destination's address (at a specified port, usually 80 / 443)
5. The server (destination) accepts or rejects the request, for this example let's say that it accepts it
6. The server sends a response according to your request
7. The browser / app renders the response gotten from the server

This is basically the flow that happens each time you navigate somewhere on the web or click on something on a page on the web
