How do you set up XBOX LIVE beside "The cable?!"?

Okay... I wanna set up XBOX LIVE and I am NOT buying a wireless adapter coz they cost loads!
I'm going to try and use an "Ethernet cable" but I dunno what I have to connect it to. Obviously you stick one expiration in the XBOX 360 but what do you do near the other end?
Can you progress on XBOX LIVE by connecting it to a laptop / computor?

You hook it up to your internet router. You enjoy to have DSL or cable. Its glib as pie lol You need to draw from a hub so that you can run your ethernet cable from the hub to your xbox. Your desktop and xbox will run through the hub which will be connected to the modem. You can get a hub from wall-mart for around 25 dollars.
