So, you've heard about this thing called a Network and want to learn how it works.

Not sure where to start? Are google searches on the topic making your head hurt because they only link to one specific part or other? Look no further. You have found the comprehensive network explaination you were looking for.

This presentation will guide its viewers through Network Fundamentals starting with the very basic and leading into complex concepts and configurations.

Once you get a better understanding of Network Fundamentals you may want to test out your new knowledge in a virtual network lab. Here are some recommended virtual labs to play with:

GNS3 is Free local machine software you can run to provide a virtual network lab. (Note GNS does not provide router or switch images. You need to download these from Cisco or elsewhere.)
Cisco's Virual Internet Routing Lab (VIRL) is a Paid virtual network lab service available in local machine (VMware based) and cloud variants.
