In each capture you start by pinging 192.168.0.105 from 104 and 
receiving a response.  Then in the hub capture you ping the broadcast 
address (.255) from .1 and receive a response only from .104.  In the 
switch capture, you are pinging the broadcast address from .104 so it 
wouldn't respond to its own broadcast ping and since no other devices 
are responding to broadcast pings as evidenced by the hub capture, there 
are no others to respond when pinging from .104.
