This is the summary lesson to the Networking Fundamentals series. In this lesson we illustrate everything Switches and Routers do when forwarding packets between two hosts. We show you each device's ARP, Routing, or MAC address tables, and show you how each are populated and/or used to forward packets.

This is the ultimate video showing you a practical illustration of how packets move through a network.

The series wraps itself around a very important interview question: "Tell me everything that happens when you type 'www.google.com' into a Web Browser".

This question seeks to discover if you understand the core of networking: How packets move through a network.
