OSI Model

First, describe the OSI Model and how it works. Then pick one layer (any layer) from the model; write a description of what that layer does, what level it corresponds to in the TCP Model, and what it covers in the real world. This should take no more than 3-5 paragraphs to do effectively.

I want your response (this assignment) to reflect your understanding of the model – it might be necessary to refresh your knowledge by reviewing some technical sources; that’s OK. But, I do not want just cut and paste information. I also want you to cite at least two sources that you used. This means you will also need an APA style reference list. A cover page is not required for this assignment.
