Describe what happens when a computer OS, on an IPv4 network using NAT, starts up for the first time, then a user clicks to open a browser, and finally the user enters www.depaul.edu in the browser window and hits enter.

Relevant topics you should consider in your response: How are we able to communicate with other devices? What communication occurs between our computer OS at each stage? How does that communication get to each device? How is that communication changed by the environment?

The answer with the diagram is kinda hard to understand, can anyone explain it!
