The first volume of TCP/IP Illustrated by Richard Stevens is wonderful. Ethernet frames, ARP, IP, ICMP, BOOTP, DHCP, UDP, TCP. Just make sure to get the original version.
Stevens' writing was engaging and pedagogically top shelf. Kevin Fall attempted integrating his coverage of newer protocols into the preexisting text, and unfortunately, completely butchered it.
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.
