I started recording a new video series covering How Data moves through the Internet. The intent of this first set of videos is to serve as the first Module of a new course I’m developing discussing Networking Fundamentals.
The full course will give anyone looking to start a career in Networking the foundation they need to pass job interviews and become successful engineers.
Moreover, this course will also give anyone in any sort of IT role insight into whatever it is “the networking folks” are doing every day. This type of cross-discipline training will propel you further in whatever Tech career you are pursuing.
How Data moves through the Internet
Module 1 of this course will be available for free to everyone on YouTube and will teach anyone the very core of Networking: How Data moves through the Internet.

The individual videos for Module 1 are available here:
- Lesson 1a – Network Devices — Hosts, IP Addresses, Networks
- Lesson 1b – Network Devices — Repeaters, Hubs, Bridges, Switches, Routers
- Lesson 2a – OSI Model — Layer 1, Layer 2, Layer 3
- Lesson 2b – OSI Model — Layer 4, Layer 5/6/7, Encapsulation/De-Encapsulation
- Lesson 3a — Everything Hosts do when speaking to hosts on the Same network
- Lesson 3b — Everything Hosts do when speaking to hosts on a Foreign network
- Lesson 4a — Everything Switches do to facilitate communication
- Lesson 4b — Everything Switches do to facilitate communication
- Lesson 5 – Everything Routers do to facilitate communication
- Lesson 6 – Packet Traveling — Host, Switch, Router, Switch, Host
- Lesson 7 – Packet Traveling — Host, Switch, Router, Switch, Router, Switch Host
Videos are in still in development.
This post will be updated as new videos are released

Got a suggestion for a topic that would contribute to this goal? Suggest it in the comments below!
Spanning Tree. Command Line frequently used commands and interpretation of their responses. Subnetting and network design considerations. Configuring tiers of user access of network devices.
+1 to STP!
Noted =) I’ll add STP to the list. Thanks Garrett / Ludlow!
Noted about STP. Thanks! “Tiers of Access” is a good idea. I’ll add that as basic network designs / topologies.
Subnetting I covered here: https://subnetipv4.com/
As for device commands, I’ll probably omit that so the course content can remain device and platform agnostic. But I have written a lot of CCNA and Cisco related articles, you can find most of them here:

audio is not working properly. plz check
Could you elaborate? Seems to be working for me. Which video?
Yes. It’s okay. I’m having issues with my audio driver. sorry for the confusion.
Hey Ed, I had issues with my Realtek audio. I had to uninstall and reinstall the driver. Great videos
Great. Glad that was sorted =). And that you enjoyed the videos!
I want more information about internet…. Please send me through e mail
Hello Ed,
Just wanted to says that I highly appreciate what you do. It has helped me understand so much about networking and how it really works behind the scenes,
Cheers
Happy it’s helped you, Steven. Hope the videos continue to help =)
Great information presented in clear and meaningful fashion.
Much appreciated and please keep up the good work!
