More Networking :\

Today we did even more networking. We learned the devices for each layer of the OSI. For physical there are the repeater and the hub. They are what make a weak signal stronger but they aren't too good because there is a lot collisions. For the Data Link layer, it is the bridge and the switch. These things make sure that only what is needed, gets through. The bridge isn't too good because it denies a lot of stuff, but the switch has multiple ports and a lot of collision domains so there is less of a chance for collisions. The Network level's device is a router. This is the best one. It is a big thing that routes data packets. They are really expensive though. See I am getting better. I understand it a little more.
