Module 1 of the Networking Fundamentals course will illustrate the core of networking: How data moves through the Internet. The foundation of that is understanding the OSI model.

But this isn't about mere memorization, instead we are going to look at the underlying goals of each layer of the OSI model, and how it contributes to the over all goal of networking: Moving data between hosts.

Before watching this video, watch the first videos in the series:

Lesson 1a - Network Devices: Hosts, IP Addresses, Networks:
   • Network Devices - Hosts, IP Addresses...  

Lesson 1b - Network Devices: Repeaters, Hubs, Switches, Routers

This lesson is a free lesson from my new course on Networking Fundamentals. The first module of this course is meant to teach you everything you need to know to understand how packets move through a network. All the lessons for the first module will be released for free here on Youtube:
