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.

Course 2213 IP Addresses, Packets and Routers
Lesson 1 – Introduction to IP Addresses, Packets and Routers
Course 2213 IP Addresses, Packets and Routers
IP Addresses • Packets • Networks • Routers • Static and Dynamic Addresses • DHCP • Public and Private Addresses • NAT • IPv6
IP Networks, Routers and Addresses is a comprehensive course on IP networking fundamentals: IP packets, IP addressing and IP routers.
We’ll see how routers implement the network with packet-switching, that is, relaying packets from one circuit to another, and how routers are a point of control for network security. We’ll introduce the term Customer Edge (CE), and understand the basic structure and content of a routing table.
Then we’ll cover the many aspects of IP addressing: IPv4 address classes, dotted decimal, static vs. dynamic addresses, DHCP, public vs. private addresses, Network Address Translation, and finish with an overview of IPv6.
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 clearly explain IP and routers, packets and addresses, the underlying ideas, and how it all works together… in plain English.
