Right.

I don't think it matters since the switch has its own power source.
If the machines are separated by a long distance, having one or more
switches would improve performance because a clean signal will always
be emitted from the "far" side even if the incoming signal is a little
dirty.
If the machines are close together, then the only practical difference
you'll notice is the cost (time and money) of locating and installing
the hardware. Hmm, the switch would use some more power too (for your
utility bill).
