COURSE DESCRIPTION

I have friends who know nothing about computer networks who own stacks of off-the-shelf routers, hundreds of feet of cable, and every wireless card you could imagine.  And yet, they've failed to figure out that their internet connection will never get any faster if they don't buy service faster than the 768k down DSL.

Not to be arrogant about what I know about networking, but a network is much more than the jack in the wall you plug the cable into.  But for most people, the end-user, this is what the network is reduced to.  For the rest of us we want to know what makes this stuff work. What are the Computer Networking Basics, What are the components, what are the technologies, protocols, and rules of building reliable and resilient networks?

This Computer Networking Tutorial is built off of three other successful courses and contains monthly updates and live sessions that explore the technologies of computer networks.  You will be provided with lab topologies that you can build into Dynamips or GNS3 network emulation freeware.  Each lecture will walk-thru advanced technology demonstrations illustrating the proper implementation of the technology.

    No Logical flow

    I'm sorry, but this is more of a "watch me" as opposed to teaching. There was no logical flow to the material and the instructor just jumped around a lot. Maybe if he creates a road map and stay on topic throughout the course it will probably be better. Also, for a class titled "Learn Computer Networking", it should build up from the basics and become more complex later. I found that the first module, "What is the Network?" to be good, but the course took a turn after that.

  • Matt McAlear
    A lot of CLI and lacking background knowledge

    Doesn't really talk about some of the core concepts of networking but goes into detail of a lot of topics before discussing the underling technology. Talks a lot about CLI commands but show them all segmented and separated without explaining well how to get to that same spot and how the network as a whole fits together.
