You are asking about all things at once, it's a big concept. Still in short.

• When you type www.google.com (or any other site name) then the request goes to the DNS server which translates the URL into an IP address.

• Then the request goes to server where the website is being hosted, the server which is providing hosting service for the website contains the website-stuff that has to be shown to the world.

No, it doesn't make any difference if you are in different class of network.
