Traveling Without a Suitcase

---

1.	The trip begins at the place of departure�your home, for example. Using city streets and roads, the you join up with a state or U.S highway that takes you out of town. This is like using LAN and WAN connections to connect to a larger regional Network.
2.	The state or U.S. highway links up to an large interstate highway 100 miles into their trip. The regional network can be likened to the state or U.S. highway, connecting the region to a much larger national or international network.
3.	The travel on the interstate takes up the majority of your cross country trip. Interstates are large highways designed to handle large amounts of traffic. This too can be compared to the Internet�s high-speed, high-capacity backbone, that carries the bulk of Internet traffic.
4.	Finally, on the other side of the country, the you use another smaller, state highway to traverse the distance between the intestate�s junction and the destination town. Once inside the town, you use city roads to go to the specific place you want to visit.

After traversing the Internet backbone, traffic is routed, or directed, to the regional network containing the destination computer. The data, or information, travels down through the WAN and LAN containing the destination computer, until the data reaches the computer. In this manner information is transported throughout the world.
