-
Video 2: Foundations: What is a Network?|35:32
This video answers the question of "why." Why do we need a network? What does the network accomplish for us? Without understanding this foundation, the rest of the Cisco certification track will not make much sense.
-
Video 3: Foundations: Living in the OSI World|43:30
If someone told you, "My car is broken," but was unable to expand on what exactly was broken, you wouldn't know where to begin looking for a solution. In the same sense, networks are an extremely complex system of communicating. The OSI Model holds the key to understanding the layers of network functionality. This video walks through both a logical and practical presentation of the OSI Model.
-
Video 4: Basic TCP/IP: Addressing Fundamentals|39:42
We live in a TCP/IP world. Having a thorough understanding of this protocol is critical to your success in any network environment.
