Module 1 of the Networking Fundamentals course will illustrate the core of networking: How data moves through the Internet. In this lesson, we'll explore Internet communication from the host's perspective. We'll illustrate EVERYTHING a host does when speaking with other hosts on the Internet.

We'll do this with two illustrations:

First, we'll look at everything that occurs for two hosts which are directly connected to each other do to communicate.

Second, we'll look at everything that occurs for two hosts to speak which are on opposite sides of a Router.

Remember, Hosts don't know what they are connected to. Our first illustration also applies when hosts are connected through Switches and Hubs. And our second illustration also applies when hosts are connected through multiple Routers.

These two illustrations will cover 100% of the scenarios that hosts use today to send data through the Internet.
