Course 2213 IP Networks, Routers and Addresses

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.

Tutorial – The Last Mile: Copper, Fiber and Wireless

Lesson 7 The Last Mile: Copper, Fiber and Wireless from the new course Introduction to Broadband Converged IP Telecom.
Here’s the full lesson free, in full quality, with our compliments.

This lesson is an introduction to network access technologies, called the “last mile”, the physical connection between the user and the network; the face of the telecom network to users.

We group access technologies by physical medium: copper, fiber and wireless, then survey the main technologies in each area.

Subsequent courses and lessons drill deeper into the technologies. This lesson is part of the introduction.

Copper includes twisted pair loops, LAN cables and old-fashioned T1s, as well as coaxial cable CATV infrastructure.

Fiber means Optical Ethernet, shared links for residences via Passive Optical Networks and dedicated links for businesses.

Wireless includes 4G LTE and 5G, used for both fixed and mobile applications, and satellites.
