OSI and TCP IP Models - Best Explanation

Published 2017-01-24
The Internet protocol suite provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed and received. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.[1][2] From lowest to highest, the layers are the link layer, containing communication methods for data that remains within a single network segment (link); the internet layer, connecting independent networks, thus providing internetworking; the transport layer handling host-to-host communication; and the application layer, which provides process-to-process data exchange for applications.
Technical standards specifying the Internet protocol suite and many of its constituent protocols are maintained by the Internet Engineering Task Force (IETF). The Internet protocol suite model is a simpler model developed prior to the OSI model.

The camera is moving based on the device around his neck. That's why it moves so much as it is trying to keep him in the middle of the frame. This video was really well explained
-
My wife left me but I enjoyed this presentation.
-
He explained this 2 Models in 20 minutes interactive with his class. Very great man there.
-
When the title says - `the best`, it really is. The teacher is good and passionate.
-
I love that I can just type anything related to my exam into YouTube and majority of the time I can find 5 or 6 classes on that subject in video form.
-
Kudos to the teacher for the great explanation of not just the OSI model as a whole, but also the different ways we can visualize the role each layer plays in the real world. Keep up the good work!
-
I swear if you're still teaching, I would be the first person in your classroom. I hope you wrote a book, because you have the best explanation of this topic that I've ever seen. Love it!
-
Best explanation ever. I can finally throw away the useless notes.

This guy is a great teacher and I am glad to see he is teaching what he loves. It makes a big difference for students when their teacher is good. Not all students will flourish in all subjects as some of them will only slowly realise that they rather love this topic or hate it. Those however who love it, with this mans teaching will do very well. I wish I had a good teacher like this in university. Would have saved me hours and hours of extra study. These students if reading this, respect this man and appreciate his teaching style, you wont find many like this.

This guy speaks my language man. Wow.
-
Year Working in IT and Never I have seen someone give, an explanation so perfect so detail like this one kudos my friend.
-
7 years after graduating from the college, i finally understood what the heck the OSI model actually means! Thank u
-
I want this guy to teach me EVERYTHING.
-
GREAT EXPLANATION! Broken down very very well! All the way from South Africa
-
I've taken 5 networking classes and this is the best explanation I've ever seen. Wish I had you back in college
-
Thank GOD for this TEACHER!! I just started out learning the OSI model and I just couldn't get it...but now I'm ready to tackle it all!!!!
-
Why would anyone dislike such a meaningful video! Thank you Sir, for taking your valuable time to provide us with such invaluable content.
-
Thanks for sharing this video, I know the layers for a long time but i never thought about the connects between each of them. He is an awsome teacher.
-
I must know the name of this teacher! I've never been so into this, and it was PERFECT for my information systems exam!
-
Really like the video. The concepts were well explained and the teacher is a great speaker. Thanks for sharing ! Learned a lot.
