You're closer to being correct on your first answer, but each station
won't get exactly 1MB.  Ethernet is shared medium.  In CSMA/CD, the MA
means Multiple Access.  All stations on that link are competing for
bandwidth on the link.  If 9 of the stations are idle and one station
wants to transmit it will have a lot of the bandwidth available.  If
more stations transmit then less bandwidth will be available per
station.

This doesn't mean that each station gets the same amount of bandwidth,
though.  Link usage in ethernet is very dynamic depending on traffic
patterns.

is shared means that there is a 10M ethernet, if there are 10 station
in
this network, every station has the 1M?

or is shared means that there is a 10M ethernet, if there are 10
station in
this network every station has the 10M bandwidth when you
transmisstion,
(csma/cd) after this station trasmisted, another can transmit and has
10M
bandwidth.

which is right?

thanks for answered :)
