This week we talked about networking hardware and the OSI model. Since I had taken the Intro to PC Administration class my freshmen year, I knew about the hardware we talked about. I didn’t know about the OSI model though. I didn’t realize there is 7 different layers. This week I also added a link to the Diigo. It’s a link to the “History of the OSI model”. It’s a short but informative page. I used it during the lab on Friday and I thought it would be very useful for the rest of the class.
