- Опубликовано: 26 июн 2024
- 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.) 😉

you are the real king in networking boss. every single word makes sense. U deserve a billion likes for this playlist.
Glad you enjoyed it, thank you for the kind words.
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 🎉
Each and every video on this playlist deserves the algo pampering. After following along on this journey, the information was becoming redundant by the time it was called out. The self awareness of the quality of information being presented is more evidence of his mastery of teaching networking fundamentals.
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 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.
Finally a video explaining how the whole network works without only explaining the concepts in isolation, thanks a lot! It is simply awesome!
At the end of the video you boldly claim: "If you want to become a network engineer there's no better start than this video series".

Indeed. There isn't. Thank you for this 💚
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!
This course is excellent. The graphics are clear, easy to understand and really add value to the course. The commentary is paced at just the right speed to explain things clearly, but at the same time to hold one’s attention. Superb effort and I look forward to future videos from this channel.
Thanks for the kind words, Alfred. I'm thrilled to hear you've enjoyed the course =). Cheers !
I can thank you enough for the explicit tutorial, you are an amazing tutor. Thanks a lot.
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.
If you are willing... Could you do me a favor? Do you mind sharing this video on Linked In, Reddit, Twitter, Facebook, or any other social media you use? As an independent creator, that would be an _enormous_ help, and I would appreciate it _greatly_ .
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!

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!!
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. =)
Dude, so many people ramble on about crap and digress, you are just STRAIGHT TO THE POINT. So fantastic, Well done!

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 =)
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.
I am watching this again, like new wine, it's evergreen. Thank you for everything.
You're welcome, Azza. =) ❤
Man, I wish I had such vids years ago, when I was learning networking
Seriously, me too! heh ;)
Your lesson preparation is excellent. The right level of detail at the right speed with good repetition to help drive concepts to long-term memory.
Thank you for the kind words. Glad you're enjoying this series!
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!
Your entire series is the best, very simple to understand, and I love it.
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! 😇
This is the clearest and most ‘human’ way I have ever seen this explained - it is simply outstanding and I recommend this series unreservedly!!!
I just finished your module. That is fantastic. Looking forward to your next modules. Thanks a lot!!!!!!!!!
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 =)
Simply Awesome !!!!!
This is literally *The* best network course, not only on the internet but maybe in every university course.
Thanks a million.
Thank you for the kind words, Johnny =). I appreciate it!
I don’t think I’ve had a better explanation of the OSI model. About to start studying for the ccna and wanted to run through this first. Thanks!
Awesome Scott! Good luck with your CCNA. I think this series is a GREAT starting point for your journey. Please pass it on to others you meet who are also on the CCNA journey =). Cheers !

Thank you, Gayan. I appreciate the kind words.
This is so detailed and concise with clear and easy to understand illustrations, thanks for pouring out your knowledge for free.
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

Thanks Ed Harmoush, Can't Thank you enough for explaining this basic concept of networking so easily ..GRATITUDE :)
Thank you, Bhavani! Thank you very much for helping support this channel. It means a lot and I greatly appreciate it!
incredibly good series. As an IT professional, I stumbled across the Network Protocols video out of general interest when working on something and ended up watching the whole series. Cool to know from a curiosity standpoint regardless of how valuable this knowledge is for any IT role
Hi John! Thanks for the kind message. Glad you enjoyed the series. And I agree with you 100%, a little cross-discipline training goes a long way! Cheers!
This video makes networking look silly simple :). And, this is better than videos you pay for to learn networking fundamentals.
This has been the best intro to networking series I have seen. I once tried another a year ago but this one just hit the spot. It addressed all my questions completely. I will need to take more advanced courses but this has laid the groundwork for it. Thank you so much.
Excellent, Victor. Glad you enjoyed the series =)

Amazing course! Very thorough, at no point there are important concepts left unexplained or poorly explained. The level of abstraction is just right: not going too deep into the technical nitty-gritty yet not missing any critical concepts. Great work, very valuable! Thank you for doing this!

Noted. Thanks Andy =).
This series of Network fundamentals clarified many of my questions, I am waiting for full course. You explanation simply awesome.
❤️❤️
This is the best series I've ever watched!
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.
Completely incredible. Can't imagine the amount of work behind this. I remember having a subject in University about this that despite the teacher being super cool, I understood nothing. You just explained the whole subject 100%!! I wish these videos were here 8 years ago!
Congratulations, and thanks a million!
You're very welcome, Jantonio. I too wish these videos existed when I was first trying to learn Networking, heh. =)
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!
I just wanted to thank you for creating this marvelous content for free. Excellent job!
Thank you. This is the first time I have actually got a clear understanding of how computer networking works.
Congrats! Glad this cleared it up for you!
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!
your videos are very helpful, atleast for my. Thanks a lot.because of you now i under stand the basics of Networking.

Glad you enjoyed it. Thanks for the kind words! =)
I like how you started out with a simple explanation about a back and forth and then tossed in a real life example of this communication because it helps to not worry about those other details when learning this videos concept. I will never forget the day you asked me to come in and go over a ticket with the new hires because you liked my work flow and documentation, this video is very similar and I will point people to it when I can.
Hey Seth =). Long time no chat!
Thank you for helping point people to this video. =)
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.

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.
Everything you put out is excellent and we're talking about you to others. I'm spreading the news and I'm proud to do so. The complex concepts you've made simple and fundamental. Please do more fundamentals.

Hi there. I realize that this video series is now 2 years old but wanted to say thanks. I am studying cyber security and this series came in so handy while we worked through the networking portion of the course. I am definitely going to be diving in to networking more as time goes by as I found the whole thing so interesting. Your videos and delivery are also SO good. Thanks alot and will check out your courses in time to come.
I like to thank you for putting this module together. Your explanation on all topics are brilliant. I cant wait to complete this full course. I hope you update soon. For now I just like to give you a prayer of having success in this world and hereafter.
