8 hours worth of lecture content from the university I attend in 20 minutes and it's more clear. Thank you for the time and effort you put into this fantastic video.

You can literally hear that you are excited about what you're teaching which is (for me) contagious, and makes learning so much more enjoyable. This is great content and has been extremely useful. Thank you!

Best summary I have seen - where was this when I needed it 10 years ago - sooperb Dan

I have literally learned more in 3 minutes of this video than I learned in 2 weeks of my current application security course. How we process information certainly resides on the type of instructor. Thank you for the help! Much appreciated.

So far the best concise OSI- TCP/IP layer explanation that easy on the brain cells.

[jamesgiaquinto]

another one to remember is " People Design Networks To Send Packets Accuratly". Love your courses. You have a better way of explaining the technical side making it easy to understand.

I've been trying to understand this for 4 days now, and I finally understood it from watching this 1 video. Thank you

[gusawa]

wow thank you sir for the very good video! understood the concept faster from here than from my

[benrich]

By far the best and the most comprehensive and the most detailed explanation of the OSI model.

When you hear the excitement in a teacher's voice you can tell he is a good teacher...

First time here, I dropped a sub and also thank very much for the slide.

[lukasa]

Thank you so much for this! This was a fantastic overview of TCP/IP and OSI model. After falling behind and struggling to grasp these concepts as a whole, this helped tremendously!

[pareshparesh]

Sir, This is awsome presentation that reflects your sincereity to teach us who does not have a clue about it. Thank you for this detailed explanation. Salute!!!!

Just completed the module for my college course for the OSI subject... Quite literally told me to read 10 page from a text book, go through one slide show and then take a test... lets just say the test didnt go so well. This video is amazing ! and I am surprised my college course did not have a video lecture on this complex system.

[xunililak]

Wish I had ran across this video years ago and maybe I could have lit the fire that I now possess much sooner! NTL thankyou!

[dhinakaranvenkatesan]

Your explanations are very clear ...even a 10 yrs old guy will understand....thanks for your demonstration

From data -> Segments (With Port address information) -> Packets ( which adds the destination IP address) -> Frames -> ( which again adds the Mac address) and then to bits.

Best video tutorial for osi model in the YouTube. We need more top quality videos from you dan.

[LisaMcGraw]

This has been one of the best videos explaining TCP/IP from bits to data. Thank you so much for this video.

[josiah]

Great explanation, I really appreciate the time and thought that went into your presentation.

[BilalHeuser]

Thanks for this wonderful explanation of OSI and TCP-IP. :)
