Question: how to answer this?
Suppose you decide to open your own business in Kansas.  You wish to have a public web server that describes your business and products/services. Naturally, you would like the entire world to be able to visit your Web site in order to learn about your exciting products and services.  You have a computer system that you can use for a web server, but nothing else (no internet). Describe the general network focused steps you would you take to put your web server on the internet and make sure that someone in Italy named "Alice" can access your site?  Describe how the routers in Alice's network become aware of your new network.
