Folks, I am having a tough time figuring this out: in a full-duplex LAN segment are there any collisions to be taken care of when (i) There are only two stations connected point to point (ii) When there are multiple stations connected through a hub (ofcourse all of them would be in a different collision domain had they been connected through a switch).
Now, for (i) since they are full-duplex would mean a station can send and receive at the same time -- so these two stations should be able to send and receive at the same time to each other without any collisions, correct?
For (ii) if they are connected through hubs but are full-duplex, when exactly does collision occur?
Lastly, if multiple stations are connected to different ports of a switch, in what situations can ethernet have packet loss? I am trying to understand the recent extensions to Ethernet aka http://en.wikipedia.org/wiki/Data_Center_Ethernet and am totally lost :(
Any clarification greatly appreciated! Thanks!
