Step 1: How the Internet is Supposed to Work

Explain that you will begin by describing a typical Internet transaction. We suggest using the whiteboard to draw out the process by which a browser requests a webpage; however, if you prefer, you can show a favorite video, discuss a pre-made diagram, etc. Regardless, it is not uncommon for participants to have questions about this introductory material.
The example below starts with a computer on a local area network (LAN), but applies equally well to any Internet-connected device. If your training is focused on mobiles, you should probably use a smartphone in your example – you can either explain that the device is connecting through WiFi, or modify a few of the terms below to account for the differences between mobile data services (3G, Edge, GPRS, etc.) and traditional ISP connections.
