This week we dove deeper into the OSI model into layer 2 and layer 3.  In layer 2 we discussed how switches work and they handle traffic on their network.  We used a whiteboard and drew different computers hooked into a switch, and then showed how these different computers data is handled when data is sent from one computer to another.  What was interesting about this is how I found it interesting how the switch initially just “shotgun blast” out the data to all users until it learns which computer MAC address is located on which port.  In layer 3 we built more on this idea of how switches work, but introduced layer 3 routers.  What does a router do?  Well from the name “router” pretty much routes data beyond what a switch can do from one network to another network.

This week I contributed a diigo link called, “5 basic switch setting you must know.”

    Did you diigo share these videos too? They seem like they could be useful.

    Sounds like things are making sense to you. Am I right?
