Network Devices – Hosts, IP Addresses, Networks – Networking Fundamentals – Lesson 1a

Module 1 of the Networking Fundamentals course will illustrate the core of networking: How data moves through the Internet. Crucial to that is understanding the various Network Devices which exist to accomplish that goal. In Lesson 1 we’ll unpack the following devices and related concepts: Hosts, IP Addresses, Networks, Repeaters, Hubs, Bridges, Switches, Routers.

This is a two part lesson. In this video we’ll explore Hosts, IP Addresses, and Networks. In the next lesson we’ll explore Repeaters, Hubs, Bridges, Switches, and Routers.
