The purpose behind using the star configuration is based off the fact that a star configuration connects all cables to a central point of concentration. This point is usually a hub or switch. Nodes communicate across the network by passing data through the hub. The reason why I wouldn't use a ring configuration is mainly due to the fact that the ring configuration is pretty much obsolete in situations like this where we are applying network topology to a huge corporation. The reason why I wouldn't use a bus configuration is because it does not cope well with heavy data... [continues]
