If a hub is used, all packets are placed onto all of the jacks of the hub, therefore both computers will see port 80 packets. Switches route traffic to the appropriate jack of the switch, hubs do not. When I wanted to snoop all traffic that a computer was seeing and generating, I'd use a hub to connect the computer I wanted to snoop and he computer doing the snooping. Yes, the builtin snooping facility of the computer I was trying to track the traffic on should do the trick. But, in some circumstances I needed a third- party snooper.
