- เผยแพร่เมื่อ 28 พ.ค. 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
04:51 - Packet Details from Host A to Host B
05:48 - Packet #1 - Host A to Host B
14:23 - Response - Host B to Host A
17:28 - Packet #2 - Host A to Host C
21:34 - Response - Host C to Host A
23:41 - Mission Successful !!!

*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.
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
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!
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.
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!
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_ .
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_ .
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.
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!

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. =)
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 =)
This is so detailed and concise with clear and easy to understand illustrations, thanks for pouring out your knowledge for free.
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.

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!
Finally a video explaining how the whole network works without only explaining the concepts in isolation, thanks a lot! It is simply awesome!
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 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. =) ❤
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 !
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!
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.💙💙💙
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 =)
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!!!
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!
I feel like I'm ready to become a network engineer lol. Kudos to you!
Excellent =)
i was watching proff messer video and i didnt get this topic but now i wont forget it . Great job explaining!!
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

Never seen or heard such a valuable teaching effort 💪
No words to express
Really thanks 🥰👍
Thank you for the kind words.
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!
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!
Glad you've enjoyed it, Anatolii! Thank you for recognizing the intentionality behind the content =).

THIS IS GOLD!!!!
Level 100 achieved.

Indeed. There isn't. Thank you for this 💚
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!
Thank you very much for this module. It was very interesting to follow !
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 =)
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!
this is one of the greatest video in networking I ever watched
Thank you =). Glad you enjoyed it, Batais.
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. =)
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.
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!
One of the best lectures I have watched here in YT. Very detailed and was explained very well. ❤
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 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.
your videos are very helpful, atleast for my. Thanks a lot.because of you now i under stand the basics of Networking.
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.
This tutorial is the best resource I found out there on networking. Thanks so much.
Thank you for the kind words, Ahmed. Glad you enjoyed it.
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.
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 =)
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_ .
Amazing course ... you use networking every day and now I actually know how it works ! Thank you so much.
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 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.
Dont know how it has taken me this long to find this channel! everything i have been stuck on or confused about during my learning has been smashed thanks to you! thank you so much for the effort you put into your videos and your teaching methods, it has helped so much.
Thank you for the kind words, Brad. I'm so happy you found my content useful. Cheers!
This is the best series I've ever watched!
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!!
I can imagine the amount of time that took you to complete the graphics and animations. You deserve many Thumbs up and Congrats
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 =)
Normally, I do not post comments, but I am so much grateful that I felt the need to write it. I have gone through all kinds of resources, various web sites, chatgpt and many youtube videos and there has always been something unclear to me. After completing this playlist, I exactly know how everything works and thank you so much for all you have taught. THIS IS JUST BRILLIANT!!!
Thank you so much for the kind comment =) Comments like these are a large part of why I make videos. So glad this helped make networking "click" for you. Cheers friend!
The way you explain + the visuals make it so easy to understand, thank you so much
You're very welcome.
The best explanations I've ever heard. I'll definitely take your course. It's a really great master's work you've done.
Your teaching approach is out of this world. Thank you. Keep up the good work
watched all the video of this module and it's amazing so perfectly explained. because of the now i have basic idea about L2 and L3 switch difference. thank you for this free module.
Glad you enjoyed it. Thanks for the kind words! =)
Throughout this series, my favourite is this one . Thank you for your incredible explanation.
Wonderful way of explaining the concept. Really amazing one!
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 =)
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!
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!
This video tutorial series is gold. I am regretting now that, why i didn't find this before in my graduation time. Thank you very much for this tutorial series
Honestly this is one of the best if not the best explanation of how the internet works that I’ve ever heard and the method of explanation was superb. You should make many courses.
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 =)
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!
This video makes networking look silly simple :). And, this is better than videos you pay for to learn networking fundamentals.
Incredibly thorough, very pleasant rhythm, great material for teaching. Thank you.
Glad you enjoyed it, Thorwald! I appreciate the kind words.
Honestly you are the best teacher in the world 👍salutation from France.
Salut, Hert! Glad you are enjoying these!
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
In-depth and simplified. Thank you, it was extraordinary!!
You're very welcome. Glad you enjoyed it.
100% best of the best. I just deleted all the videos that i saved before. You gain a follower and i will recommend everyone to your channel sir
Thank you for your support
Wow, you made me understand it amazingly.
I was about to give up my course because networking is the most difficult module for me.
Big thank you 😊
You're welcome, Sanaa! Networking is often explained in very complicated ways. I was hoping this series would be an exception.
i feel myself as finishing bachelor degree of networking after the series, thanks for you golden videos!!!
I really appreciate your effort with this course! really comprehensive and detailed!
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.
Azza! Thank you so much for the kind words and helping me spread the word about this content. I appreciate your support!

Thank you =). Glad you enjoyed it! And you're welcome!
Great stuff!! Really grateful for the course. would definitely wait for the paid course.
Glad you liked it, Sriharsha! Hope to have you in the full course (when I create it!)
Every now and then i will return to this video to refresh my knowledge. This entire module was fantastic. I have truly learned a lot in terms of how data traverses the internet. Thank you for this insightful Module.
