| The OSI Layers and Protocol Stacks |
This course is the first course in both the Certified Telecommunications Network Specialist (CTNS) and the Certified IP Telecom Network Specialist (CIPTS) certification packages.
This course establishes a framework for all of the discussions in subsequent lessons and courses: the OSI 7-Layer Reference Model, which identifies and divides the functions to be performed into groups called layers. This framework is required to sort out the many functions that need to be performed, and to be able to discuss separate issues separately.
You'll learn what a layer is, the purpose of each layer, see examples of protocols used to implement each layer, and learn how a protocol stack really works with the famous "FedEx Analogy" presented as an embedded video by our top instructor, Eric Coll.
Based on Teracom’s famous Course 101, tuned and refined over the course of 20 years of instructor-led training, we'll cut through the jargon to demystify layers, explaining the jargon and buzzwords, and most importantly, the underlying ideas, and how it all works together... in plain English.
