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?
just enter a word in the search box of this site, and they will teach you everything.
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…)
