OSI Model

Keep in mind that OSI model is not laws of physics. It is only a guideline. While many protocols fit neatly into one of the seven layers, others do not. But OSI model is a great tool to learn and understand how network hosts communicate with each other. Any serious network professionals and students should know about it.

The best Explanation on OSI Model I have seen on KZbin so far! Good Job Sunny.

Sincerest thanks, Prof. Sunny! You have this incredible talent for communication and explanation. You are a wonderful teacher and St. Mary's is VERY lucky to have you. I can only imagine how great your live lectures must be! :-) Much gratitude & appreciation!

[@Djsanddy]

I repeat myself. you are one of the best teachers on youtube. I saw so many videos but did not understand OSI model and finally with you video just saw it once and now I can explain it myself to others :)

Thank Sir, You have performed the work of presentation layer, you made the concept of OSI model understandable to everyone.

The clearest explanation I can find on KZbin. Once again Sunny, you are helping me teach my data communications students. Thanks!

[@JahaRo]

I've watched a few other videos and your explanations as to what each layer does and why certain protocols fit in those layers finally clicked with me; you do such a good job of relaying information. Your videos are incredible, an invaluable resource, I can't thank you enough!

[@alicialow577]

Thank you for explaining the OSI model. This litereally compressed 90 minutes of Lecture into 12 minutes and this is more understandable. I am time-conscious as I am cramming for mid-term exam which is in 2 hours' time.

[@mipatpatmi6908]

As a person familiar with the Network stuff from college, I remember I had to learn the rules from books few hours. And now I see that watching your excellent explanations would cause better degrees :)

Thanks once again for your explanations. When you are talking about the logical paths between sender and receiver, i think you missed the session layer. If that can be included i'll be glad. But again thanks for perfect explanation. Preparing for interview and enjoying your courses as a refresher.

"Sender's application layer generates data, while the receivers application layer ???" Not sure what word he said after that, according to subtitles it is "rays", but I doubt it. Still though, you have the best straightforward explanations Sunny!
