I need to learn complete networking concepts starting from basics like OSI, TCP/IP models, protocol stacks, Addressing, Subnetting, Routing etc. Any good resource online that can take me step by step?

    Hello, this is a link for the pdf file for SYBEX, Network Study guide, fourth version.  This is the book that was required for passing the A+ Networking last year.  Probably there is a new version for this year.  It should be good enough to learn what you want

      Hi fidelis, I understand you're being helpful, but please dont post links to copyrighted material, it will get us delisted from Google in a DMCA complaint.

    For beginners I recently found a nice Introduction to Networking from Intel.

    For the OSI Model there is a nice concept and explanation on Petri.

    Other then that the Cisco Wiki has pretty much all the information you will ever need.

    Networking & network topology, protocols, technologies and everything is such a huge topic that you will hardly find a Step-by-Step guide on the Internet.

    If you really want to learn this stuff I suggest some paid classes or course about that.

    Professor Messer and TheNewBoston I think are the best. If you're willing to spend a few hundred dollars Train Signal has a really good course on Networking. VTC also has a well designed course.

      I second the VTC one, really helped me to pass the Network+ first time (though, admitedly it wasnt exactly difficult…)
