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.

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 :)
