I've posted a new "Introduction To Networking" tutorial series that every CCENT, CCNA, and Network+ certification candidate needs to get their hands on.  Thankfully, it's only a click away!

The first three parts are up now:

Introduction To Networking:  What IS A Network?

Intro To Networking: The OSI Model

Intro To Networking:  The TCP / IP Model

When you're done there, head over to Amazon and grab a copy of my new Binary, Subnetting, and Summarization Mastery guide!    This is another must-have for every CCNA, Network+, and CCENT candidate.   I gotta have a few bucks for this, but I think you'll find the price very reasonable.

By the way, grab the paperback edition and you can then get the soft copy for 99 cents!

Subnetting Success For Your CCNA And Network+ Study is just a click away.  

Thanks to all of you who already have a copy.  Thanks to you, this book went straight to #1 on Amazon's Cisco Certification Guide sales chart!
