A hub would re-broadcast every frame received on one side
through to the other side.  A switch will only forward traffic
that actually needs to go to the other side (or that it doesn't
know where it should go).  Think 'bridge'.  

Bloody new-fangled terminology obsoleting all the stuff we 
learned years ago by re-labelling old stuff with new names.  
I'm telling ya, they do it on purpose, to make us feel old
and out-of-date... :-)

Later,
Kenn
