1. My homepage is google...

I don't know much about these things, so correct me if I'm wrong. When we set our browsers to visit a "home page" on launch, is it a bit like leaving on the little red light on the TV all the time? i.e. although it only uses a little bandwith, does it all add up to an enormous unnecessary usage?
