[SATLUG] Network+ question collision domains

If the NICs are full duplex then each interface would be a collision domain.
The only point of contention would be in the kernel. For example, if a
packet arrives on nic1 and nic2 at the same time, the network stack has to
make a decision on which packet gets sent out nic3 first. Its not a
collision per say, but you will see performance degradation with high

I have a virtual server running with three nic cards.  each nick card is
bridged.  One bridged nic is connected to the the DMZ router/switch, another
one is connected to my private router, and a third is connected to a
separate experimental network.  the virtual server itself lies behind the
private router and hosts a 2 webservers and a mail server inside of the DMZ
and a LTSP sever on my experimental switch.  finally each bridge nic can
accomidate up to 10 hosts.


given that the nics are bridged do the hosts connected to that bridged nic
constitute a collision domain?
