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.   http://en.wikipedia.org/wiki/Broadcast_domain
The c/d domain is where there is more than 2 nodes that can transmit
and "collide" with each others data-switches/bridges seperate these.
http://en.wikipedia.org/wiki/Collision_domain
Hubs extend the collision domain.
Routers seperate Broadcast and collision domains.
Switches seperate only collision domains.




I think..

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.

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.

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.

What do you know so far?  What specifically are you having trouble
understanding?
