We’ve already taken a quick look at the OSI Reference Model, and we’ve checked out Ethernet, which is the most popular networking architecture on the Physical layer of the OSI Model. (And a little bit of Ethernet acts on the Data Link, or second, layer.)
So we’ve already gotten a start. Today, I want you to research the OSI Reference Model itself. Let’s do it this way:
- From the Research Links, open a Cornell Notes page. Type in your name and date, and then hit the F12 key that gives you the “Save As” box. Change the saving folder to “My Documents” and save with the name “osi model research” and include your name in the file name.
- Use the Cornell Notes page to organize your research.
- Find the history and origin of the OSI Reference Model. Remember, if you’re using Firefox, you can right-click on any word (or highlighted phrase) , click on “Look up on Answers.com” and check out the meaning of a word or its entry in an encyclopedia.
- Also write or find a paragraph explaining each of the 7 layers of the OSI Model. You can use Google or any search engine you like, or you can use any of the several great links among the Research Links on the blog.
- Find and copy any good pictures and graphics of the OSI Model and then paste them into your Cornell Notes page(s). That will save them for later.
Okay! Good luck finding all you need to know about this really handy model for understanding the way networks work. That’s what the OSI Reference Model is all about.
Be sure to save your work from time to time…
