Class Session: Wednesday Jan 24, 2018
We are doing this class Monday, January 29, in place of the lab. Here is a link to the class exercise we will do today.
These Khan Academy videos serve as a great introduction to our Networking session. I want you to actively watch these videos before coming to class so read over the associate keywords I have listed on this page under each video link. Most of these keywords are at least briefly mentioned in the video.
This class will be collaborative in nature and you will have the opportunity to get to know your classmates better, so this class will affect your value added grade more significantly than any other class this semester. If you are 🤧contagious🤒, though, don't bring your germs to class; I will find a way for you to make up the class 👍 .
If I have found any other relevant links or videos associated with the term, that term will have an link to the source. if you see this arrow , then I have provided a related link that was not mentioned in the videos.
