Network chuck covers the basics. The only thing I would warn is that he only covers the extreme basics. Like the top 1% of networking. But he makes it sound like when you are done with his videos that you are ready to go make $250k as a network engineer.

So yes he's entertaining, but I only look at it as entertainment. The learning materials are barely more advanced than you can get from skimming an introductory blog post on networking.

Indeed. While I respect him, I don't like his caffeinated, manic presentation style and his material is far too basic for me. I suppose his presentation style is to hype up learners on an otherwise boring topic (for most, I personally love networking).

Nonetheless, he is quite popular with the early learners, such as OP.
