What affects the relative scalability of hub, bus, and ring topologies?
What will be an ideal response?
Hub:A hub simply repeats whatever it gets to all other connected components.The device itself is limited only by the number of ports it has for broadcast.It will create additional messages on the network because it does not discern a recipient.
Bus:The bus is hindered by the competition of devices connected to it.Every device must compete for use of the media, so there will be a larger and larger number of collisions as the number of devices attached increases.
Ring:The ring is limited by the singular communication direction, increasing the path for a message to reach a random recipient by the number of devices added.This particularly affects messages flowing in the opposite direction of the ring connections since they must travel almost the entire circumference of the ring to reach the intended destination.
