i don't really know anything about networking so this is probably a very very simple question. all i want to do is connect my xbox and computer to the same connection. where i get confused is the different type of connections. the only one's i see mentioned are when you connect to a cable/dsl modem then to the wall. well this is on my school's network so it's just a standard ethernet plug in the wall sort of thing. so, i guess what i'm asking, is should i get a switch, hub, router and what are the differences?? please help. thanks.
