The Internet as an analogy to a city (Score 1)

The Internet is the series of roads that lead to all destinations. Traffic lights are the routing rules that control the direction and flow of data. Cars are packets. IP addresses are locations or places on the Internet. Host names are equivalent to calling '12321 Main Street' 'Bob's house'. The interstates are the Internet Backbone and allow you to cover great distances within the city in a shorter amount of time. Toll roads lead to ISP specific content. etc, etc, etc... This also works well in describing bandwidth saturation (traffic jams) to non technical people. If you make your roads wider, your traffic is less congested and therefore moves faster from point to point. When you move from a three lane road to a two lane road, you tend to get traffic jams at these bottlenecks in high activity periods.
