Direct & Understandable

I discovered NetworkLessons.com when I was entering the field a few years ago. After reading Rene's books, his examples and videos helped pull the concepts together. If you want lessons that get to the point fast you will like what this site offers. It's great whether you are new getting in the business, or just trying to understand a new networking technology to apply on the job.
