Title: Clarified the purpose of each layer of the OSI model.

I have added a little more depth to the discussion of each layer in the OSI model.

I also wanted to propose that the rest of the Networking 101 material be re-organized to more closely follow the OSI model described at the beginning of the lesson. For example, the current outline describes the OSI model, then jumps all the way to IP addressing and subnetting before getting back to Layer 1 topics like fiber vs. copper only at the very end of the lesson. I will take a stab at reorganizing, but thought that belonged in a separate pull request from this one.
