non-gate collision

Question

if sender A in network1 is sending packet to receiver B in network2 . The networks are connected by a router1 .At same time, receiver B (or may be some other host in n/w 2) is sending packet to A in network1.

then collision happens or not? I know that each port on a router is in different collision domain.But then how the router would deal with the above situation?? plz explain...asap

Answer 1

there will be no collision because both the packets will be buffered at the router and will be sent to their respective destinations.
