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.”
