    Most Effective Teaching Method

    Having studied networking material from countless sources over the last 20+ years, I have to say that the hybrid textbook/lab scenario approach of NetworkLessons.com is one of the most effective teaching paradigms for me. They strike a balance between theory and practice, and their step-by-step illustration method to demonstrate various concepts and behaviors–ones which are normally very abstract and boring to read on their own, come to life and suddenly seem simple and easy to digest.
