Q:

You are on a new browser with nothing cached and a default web browser of Google.com.

You go to the address bar, type, “Top Ten Cat Videos” and hit enter. What happens?

A:

Your machine will get an IP address via DHCP. It does this with a UDP address.

After getting an IP address, it’ll hit up the DNS server and ask for the IP of the website (Google.com). The protocol for this lookup could be UDP or TCP.

Now we can start a connection with Google.com

We’ll send a HTTP request with the query. This is done with TCP.

The data is encapsulated and travels through various places until it reaches Google.

Google will send a HTTP request back over TCP/IP.

This request will give you a resuable HTML page template, and some database results that the user will user to construct the page.
