Information Technology in Theory
"The text is accessible, the concepts understandable - just what's needed for a freshman-level text." -Robert Friedman"Fantastic job of treating an important, current technology topic at a reasonable level for an introductory IT textbook. I have not seen anything comparable yet in other textbooks directed at the target audience.  The discussion of the different modes (soft IP phone, ATA-interfaced, etc.) is excellent and the Case Study at the end of the chapter is terrific and encourages students to actually "test drive" VoIP technology.""Overall this chapter is the best I've seen to-date at this level of discussion."
