Everything Switches do - Part 1 - Networking Fundamentals - Lesson 4

Switching is the process of facilitating communication within a network. Switches are simply device's whose primary purpose is Switching.

This definition is intentionally worded as such because there are many devices that claim to do "switching" -- and all of those devices will follow the same rules and processes that Switches do to facilitate communication within a network.

In this video we discuss Switches as L2 devices, MAC address tables, and the three fundamental switch actions: Learning, Flooding, Forwarding. We then compare and contrast the act of sending data THROUGH a switch vs sending data TO a switch.

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 are a lot of great networking tutorials on Youtube but this series is by far the best. You explain everything so clearly and with great examples to help reinforce the knowledge. Thank you so much for taking the time to make these videos, they are absolutely fantastic.

[wylie]

This course is one of the best tutorials I've seen. Thanks for all your effort.

[coolnerd]

Your genius at explaining something in such simplicity is out of this world.
Thank God very much for your existence.

[adedejiemmanuel]

I am watching this again, like new wine, its evergreen. Thank you.

[matthernandez]

Criminal you're not doing the entire course. I'm entering back into university and this is such a flawless tutorial from top to bottom. I'd have no issue paying for the full course.

[omarberraqui]

the best ever to explain Networking Fundamentals period

[KA-flqt]

Learn, flood and forward. i will never forget this about switches. Amazing explanation. I can not skip any of these videos .

[bbqconstruct]

After finishing the playlist, I will be purchasing the Full Course to extend my gratitude to Ed. I'm sure the TLS Deep Dive won't be too far off too!

[nicolasgoubin]

Okay. I knew nothing about communications and how internet worked in general. Your tutorial playlist on networking is GOLD, and i seriously mean it !

Now, i can think of how i can architecture my network at home, how i can create my personnal server and how i can connect to it... Even from another location, through internet ;)
Thank you a LOT !!!

Hey Practical Networking.. I just wanna let you know, that lately I've been trying to learn about networking to help better understand a career I want to go in. I am so thankful that you are here to help us learn about this. I am understanding practically everything (with research here and there) easily and I'm becoming more comfortable pursuing this kind of career. This is as far as I am now, and I want to say thank you again for providing us with this information and illustration. I have a lot of patience, and I have been doing the same job for almost 13 years now with fast food and I've always been interested in computers and technology since I was a kid, even automotive which may have some common deployment since cars are becoming more and more electronic. This seems like a fascinating field and I will keep pursuing it.

[djjayem]

Please continue creating more networking videos. You explain it in such a way that I always understand by the end. The best out there for me. Would love to see you cover all the aspects. Thanks for spending the time to put these together for free!

[kirankumar-syxb]

By far one of the best series on Networking I can say. Whoever wants to know the basic and in detail concepts of networking can simply ignore other contents on you tube and just watch this one. It gives you all necessary knowledge with great examples.

Hey @PracticalNetworking,

Thank you so much for posting this tutorial and helping us in understanding the concepts in simple and best way. all content I was searching about networking in the past two days, I have got it in this series itself. I will definitely recommend this to others and share the videos as we.. Thanks once again for posting this kind of tutorials which are helping us a lot.

[kaidenqi]

Thanks again man. Clear, well structured, and to the point. Perfect for a newbie.

[MadaRook]

I really appreciate your lessons that you have created.

[jeytis]

Excellent! You're kind of a computer networking wizard, very good at explaining how it works. Thanks for sharing your knowledge.

[lifeisbeautiful]

One of the most practical series and so easy to understand difficult subject. Please create the full fundamental course, I think whoever will watch it, definitely get benefit from it. Also, if you can have some lesson on i.e Network types on VM, i.e. NAT, Host only etc work & How Kubernetes and WAN technology works in basic, then I will be grateful to you. Thanks a lot
