The b/c domain is an area where any node can transmit to any/all others-seperated by routers-if the broadcast domain is too big it will severley slow the network down(dependent on protocol used) as every node on the network(except the one transmitting) will have to recieve the broadcast.

c/d domain is where there is more than 2 nodes that can transmit and "collide" with each others data-switches/bridges seperate these.

extend the collision domain. Routers seperate Broadcast and collision domains. Switches seperate only collision domains.
I think..
What do you know so far? What specifically are you having trouble understanding?

Pretty much bob on.
Thanks again! btw is there a shortage of CCNAs in Europe/worldwide?
btw there is a b/d for a local broadcast and a directed broadcast. which exactly are u referring to? b/d's are not that too simple to define without knowing if it's a local or directed.
I am not aware of any shortage.
TBH where I work I don't think a CCNA really counts for a lot - we have them coming out of our ears so to speak.
P.
On the contrary. The term broadcast domain is used almost exclusively to mean L2 Broadcast domain.
Not sure why it matters. Broadcast frame is a broadcast frame. It only matters at the final destination. No one (during transit) will know or care if it's a broadcast address or not.
