Packet Tracer is a Cisco product used for designing data communication networks. I used it to teach the Cisco networking classes and the CSIS 202 Introduction to Data Communications class several years ago. I haven't taught that specific class in years, but I am in the process of rebuilding the lessons from that class since it is essentially a networking fundamentals course and I thought others, like yourself, might get some benefits from learning the material. It's still pretty rough right now as I am updating it from the ASP format it was built with to the ASP.NET format we now use on the cis.msjc.edu Website. A lot of the videos were created in the old Flash SWF format and I'm having to convert those to mp4 video files as well. You can view my progress at cis.msjc.edu/Courses/CSIS202/Lessons.
