During most casual conversations about ethernet I've heard "you can
have a maximum of four repeaters between any two nodes on an
ethernet".  I took this to mean that you can have five segments
max with nodes on each segment.  I recently read a short blurb
that said something like some of the segments cannot have nodes
on them - the three in the middle, I guess it meant.  Is this so?
Say it isn't ...

I also heard of something called a "link segment" or "inter-repeater link"
that someone quickly and poorly explained as a longer-than usual segment
between two repeaters w/o nodes on it.  I guess with one of these
links you can exceed 185m thin and 500m thick?

What if I had a maxed out network - repeater-wise - and I just wanted
to make sure that the farthest workstations could collide with eachother
properly within the spec.  Is there a device that I can put on the
beginning of segment 1 and the end of segment 5 that will test this?
