In spite
of the advantage of the extensibility of a Bus topology,
there are still disadvantages and problems. Which problems
have to be faced in a bus-topology ?
We
provide a set of different answers and use the same
animation to explain why the answers are correct or
wrong.
Is there any correct answer in the following choices?
d)
If several computers send messages at the same time,
the bus become congested and we may have collisions.
Reminder:
principle of Bus-topology
in comparison to point to point connection
Answer: Indeed
this is the main disadvantage as well as the biggest problem in a bus
topology. Since all computer send data over the same channel,
collisions may occur.
