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? The computers communicate with each other before they send a message. Collisions can not be avoided. If a collision is detected the transmission has to be repeated. Computers send messages only when the bus is free. Every computer can only send data at a specific time (time slot). This time is assigned to it in advance.
Answer: Correct!
