- This is the summary lesson to the Networking Fundamentals series. In this lesson we illustrate everything Switches and Routers do when forwarding packets between two hosts. We show you each device's ARP, Routing, or MAC address tables, and show you how each are populated and/or used to forward packets.
This is the ultimate video showing you a practical illustration of how packets move through a network.
The series wraps itself around a very important interview question: "Tell me everything that happens when you type 'www.google.com' into a Web Browser".
This question seeks to discover if you understand the core of networking: How packets move through a network.
00:00 - Intro
01:03 - Routing Table, ARP Table, MAC Address Table
02:55 - Populating the Routing Tables

*Full Course Status: Wait and See.*
Hopefully you've come to realize that I put _a lot_ of effort into the content I create. I'm not a course creator that will simply turn on the screen recording and ramble, then call that teaching. I meticulously plan _every_ module and lesson to _maximize the learning and value_ for the student.
To that end, it takes me a while to put together courses. If I'm going to dedicate the time, resources, and energy to putting this full course together, I need to know that there is enough interest in the full course. I'm rating that by how wide a reach this series achieves.
*If you are interested in seeing the full course developed, then the best way to bring that to fruition is to spread the word about this content* . By itself it already conveys _a lot_ of value. So sharing even just the 7 lessons (13 videos) in this series will surely help whoever you share it with.
Plus ... many online communities would greatly benefit from these videos. Think of all the Internet points you could acquire if you shared this series (karma, likes, follows, etc.) 😉

There is NO ONE that can break down, and clarify, these fundamentals (and even the more complex stuff, like TLS) like Ed does. He is an absolute guru at communicating this content.
yes I totally agree, he made it so simple that a child can understand it 🎉❤❤❤❤❤❤❤
Perfect 🎉
Hi Ed
I am an electrical engineer working in VoIP. I spent this weekend going through this Networking Fundamentals module. It has filled in so many holes in my knowledge! I feel much more confident about my work. Thank you for making it so understandable and easy to follow. Really amazing.
Can't stress enough how valuable these videos are. Great work Ed, thank you for everything.
Glad you've enjoyed them, Fares =). You're very welcome!
No words to express my thanks to your effort. Even though I have read this concept many times through pages of networking books, this video gives altogether different perspective of learning!!. Extraordinary!!
You're very welcome. Glad you enjoyed this!
Very true
I really appreciate you for letting us to learn about networking fundamentals for free besides that the way you teach is super clear and easy to understand specially this lesson was my favorite lesson Thanks again.
This is so detailed and concise with clear and easy to understand illustrations, thanks for pouring out your knowledge for free.
I never made a comment on a youtube video in 10 years but dear from the bottom of my heart..God bless your soul brother.....i don't know what to say as no words can describe the efforts you made...🥰🥰..
I'm honored to have your first comment on my video. Glad you enjoyed it. You're very welcome, Atul.
I've studying networking for the last 7 months, I was able to recognized/understand %85 of the steps on the data flow, the other %15 left I wasn't completely confident was so greatly explained that I hope I'll never forget, and the final analogy was pure gold, it all make sense, 20 minutes and done. Thank you.
You're very welcome. =)
If I didn't find this course, no way I could understand computer networks and clear this course in college...thank you so much, man... will always be grateful to you❤😊
Glad you enjoyed it, Suraj!

I don`t know if it`s possible to explain these things more cleare than you did. No water. Only core idea. Step by step. Thank you for that!
Amazing content! Just went through the networking fundamentals playlist and my brain just blown away. Thank you for sharing such a helpful, informative and exciting content with everyone! 😇
I really regret not discovering this series earlier. My final semester studying computer networking at university was a complete disaster. I attempted to learn from various teaching channels, but they lacked focus and coherence. I'm incredibly grateful to you for producing this series. Thank you immensely.
Dude, so many people ramble on about crap and digress, you are just STRAIGHT TO THE POINT. So fantastic, Well done!
I try to be respectful of my viewer's time =). Glad you enjoyed the video!

These are GEMs of lectures on Networking. All ~700pages networking books are like garbage infront of the videos on this channel.
Thanks a lot.
Thanks for the kind words =). You're very welcome =)
best teaching ever saw. if you have rough idea then you can become expert with solid confident.
Thank you, Gayan. I appreciate the kind words.
Finally a video explaining how the whole network works without only explaining the concepts in isolation, thanks a lot! It is simply awesome!
I've studied all lessons and I am thankful
Excellent, Albano. Congrats. Hope they help you w/ your Networking journey =)
You are amazing , i cant belive i spend money to a course from a very famous youtuber (dont want to say the name ) 80 hours of video and you are saying half of his course in 1 hour and way beter. Good job
Glad you are enjoying this series =)
I am watching this again, like new wine, it's evergreen. Thank you for everything.
You're welcome, Azza. =) ❤
I am a software developer and was not much interested in networking.
As part of random search I have gone through network protocol video. After watching that video, I have decided to go through entire series which I just completed.
In my opinion, every single minute of the entire series has most valuable content.
I think it would be very hard to get such content even with paid course.
Thank you so much for such a precious content at free of cost.
Thank you for the kind words, Ankit. I'm so happy you got so much from this series.

Man, there is no other series, not even the ones that are made with expensive software and hardware by so-called professors, come close to this series. I would like to thank you for your work and if I ever make it anywhere in this field, I will compensate you for this. But for now I send you positive energy and good karma. I also like, comment on, share every singlw one of your videos. You deserve it. Thank you!!
Ok, so I don't normally comment, but Thank You For Everything You Taught Me. I am now a student, and you are Sensei !!!! You are aewsome!! Thank you.

This is the clearest and most ‘human’ way I have ever seen this explained - it is simply outstanding and I recommend this series unreservedly!!!
This class is just perfect! Everything is explained very clearly and I think few people can explain this in such a good way. Thanks for this course, I understand everything much better now!
Hi Joran =). So glad you enjoyed it.

The hardest thing is to explain hard things in a easy way. You’re the best.
This is the best explanation I have seen in my whole career regarding OSI and how data moves in a network. Thank you so much for taking the time to break this down.
This is hall of fame level of explaining a concept that has been ephemeral for so many years

This will be the best networking fundamentals video in the entire world. Explanation is crystal clear and I was able to get a solid foundation on basic networking concepts covered in this series. Keep up the amazing work brother.
When you said the interview question I pause. The video and explained it correctly… I really appreciate PractNet … I will continue to make realistic progress(watching these videos) towards a worthy ideal(Network Engineering career). That was an Earl Nightingale quote by the way.
Fantastic to hear, congratulations, Will. I commend you on your goal of making a Network Engineering career. Thanks for the quote from Earl. Cheers.
Thank you for these series, I had to refresh what I learned in CCNA and this was straight forward with all key points needed. I appreciate your hard work!
Studying for my CCNA and just stumbled upon this as I was trying to refresh my knowledge before starting my Boson practice tests. Out of all the videos I've watched this has been the most comprehensive and easily digestible breakdown of how data flows across a network. Excellent content!
Very helpful and straightforward video. Thank you!
You're welcome =)
One of the best lectures I have watched here in YT. Very detailed and was explained very well. ❤
This is the best networking fundamentals lesson and series I have ever seen. Thank you! Please keep doing what you are doing. I will search your courses first before others.
The way you explain + the visuals make it so easy to understand, thank you so much
You're very welcome.
I knew nothing about networking even after doing my 4 years course of BTech IT. I always attended interview with the fear of what if they ask about networking. After watching your series I'm like now am gonna teach networking to the interviewers my confidence level is to the top. Love you♥️ and thank you for helping me out . Once again here is my ♥️.
I can thank you enough for the explicit tutorial, you are an amazing tutor. Thanks a lot.
The ultimate video ngl, just perfectly explained
Thank you for the kind words =)
Wow! I had the day off today and chanced upon the series. Couldn’t stop watching and went through all. I know it is not good practice and I will not claim to have internalized all the great stuff but the flow is incredible. Thanks so much for putting this together. The delivery is fantastic. Now I have a great reference and can take my time to dive deeper. Thank-you!
i enjoyed learning about the OSI model. it gave me a clear understanding on how everything works and it made the rest of the course much more easy. thank you very much
I do not usually comment but honestly this is a GREAT video to understand how data flows through the internet. Pure gold
Thank you very much for the kind words, glad you got so much out of this series =)
Man, I wish I had such vids years ago, when I was learning networking
Seriously, me too! heh ;)
Without question, this is the BEST networking fundamentals course I have ever taken, and I've taken several. Bravo!
Thank you, Bob. That is kind of you to say =).

Amazing course ... you use networking every day and now I actually know how it works ! Thank you so much.
An amazing series. I am so grateful for this. The break down and explanations you provided of complex technologies and protocols is amazing. Well done!!
Throughout this series, my favourite is this one . Thank you for your incredible explanation.
I've watched all videos of this network fundamentals course. This is the best course for newbie I ever seen. Great work. Thank you so much.
This video makes networking look silly simple :). And, this is better than videos you pay for to learn networking fundamentals.
This video series is Fantastic! I really love wholistic practical focus on understanding the entire process not just a single aspect. I also love the verbose repetition and I agree that it really helps me to learn. I have two routers in in my home office network, one of which is running OpenWRT. The routers are connected to each other but only one can access the internet. This course has helped me to understand the things I need to check in order to figure out what is going wrong.
Hey, glad you got so much from this series =). Love that you're able to make practical use of the knowledge =)
This course is the best anywhere. I struggled with many other courses and yt videos but now have complete clarity. I will continue with all of the free training and will pay for any other training that is available from the creator. Very well done. Thank you sir. You should be proud of your work.
Each one of the videos are the best. Thank you. Will recommend it to anyone and everyone that need to know about or learn about networking
Thank you, Sony. I appreciate you supporting this channel.
Your teaching approach is out of this world. Thank you. Keep up the good work
The best explanations I've ever heard. I'll definitely take your course. It's a really great master's work you've done.
lot of thanks for the free lessons. congradulations to me for finishing the network fundamental modules. congradulations to u too. Receive lots of love from Kenya
Cheers, Nicholas. Congratulations on finishing. Consider Subnetting next =)

This is done so outstandingly well. Its gonna take many views to get it solid in my head but clear and clean presentation as always! No one does it this well.
This is my one and only reference whenever I get stuck or want to go back to things in Networking. That's all I need to say. Thank you so much.
You're welcome Mostafa =)
Hello, I am not an English speaker and my knowledge of English language is not much, but the explanation was so simple and fluent, I learned the whole thing completely.
thank you so much.💙💙💙
very well taught, amazing course! I enjoyed every one of the episodes, especially about the OSI layers 2 to 3, now I understand a lot more about what IP addresses are and what MAC addresses are for, thank you!
I will call this as "Simply beautiful" Thank you so much!!
Thank you for the kind note. You're very welcome.
Such a helpful series of videos. Everything was explained in a way that was easy to follow along. Thank you for putting all this useful information together!

This video is awesome for anyone who wants how data cross over the internet and is received by the intended recipient. I am not an IT person (my background is in business and politics), but I understand the concepts (e..g, OSI, protocols, ports, and a little bit of subnetting, among others.). Thank you very much for the very well-prepared video presentations.
Thank you, Antonio. Glad you enjoyed the content and it helped shed some light on what is going on inside computer networks =)
This is an amazing tutorial. Thank you very much sir.
