Course 2212 The OSI Layers and Protocol Stacks
Lesson 3 – Protocols and Standards
Click the image below to view the lesson.

Protocols & Standards • OSI Model • Layers • Protocol Stacks • FedEx Analogy

This course begins the “IP courses” in the Certified Telecommunications Network Specialist (CTNS) certification package.

The OSI 7-Layer Reference Model is used to sort out the many functions that need to be performed, to be able to discuss separate issues separately. The functions are organized into groups called layers, which are stacked one on top of the other. This allows us to relate different pieces of the puzzle in subsequent lessons.

The course starts with the big picture, then one lesson for each layer, then protocol stacks.

Course Lessons
1. Introduction
2. Open Systems
3. Protocols and Standards
4. ISO OSI 7-Layer Reference Model
5. The Physical Layer
6. Data Link Layer
7. Network Layer
8. Transport Layer
9. Session Layer
10. Presentation Layer
11. Application Layer
12. Protocol Stacks
13. Protocol Headers
14. Standards Organizations

Based on Teracom’s famous Course 101, tuned and refined over the course of more than 25 years of instructor-led training. You’ll learn what a layer is, what the layers are, what each one does and examples of where things like TCP fit into the model …and how it all works together… in plain English.
