In this lesson, we explore various ways data are sent across both private and public wide area networks.  Some of this tech, such as frame relay, is getting harder to find in actual implementation, but you need to understand it for the exam, and for dealing with organizations that still might use it.  The script for this video, available for download during the intro, is formatted as an easy-to-use study guide.
