OSI Model #

Lesson Content #

Before we can look at some practical networking stuff, we have to go over some boring jargon that you’ve probably heard of before. The OSI (Open Systems Interconnection) model is a theoretical model of networking. This model shows us how a packet traverses through a network in seven different layers. I won’t get into specifics of this model, since most of these networking courses will be focused on the TCP/IP model, but it should be mentioned that such a theoretical networking model exists and has actually played a large part in the TCP/IP networking model that we use today.
