is a single Switch better than 2 interconected by a network cable. I'm asking this as the computers that i want to network are spread over 3 floors. The broadband modem is on the ground floor, along with a computer. the first floor has a single computer and maybe an xbox. and the third will just have a computer. i would only like one cable running in between floors if this is possiable. can you suggest how to set this up as i haven't done networking before.

its going to have to be wired as i need the fast transfer rates.

thanks for your help
