Describe the star network topology (essay)

In local area networks where the star topology is used, each machine is connected to a central hub. The star topology allows each machine on the network to have a point to point connection to the central hub. All of the traffic which transverses the network passes through the central hub. Advantages: *Easy to install and reconfigure. *No disruptions to the network when connecting or removing devices. *Easy to detect faults and to remove parts. *Less expensive. *Includes robustness, that is, if one link fails, only that link is affected, other links remain active. Disadvantages: *If the hub fails, the whole system is dead. *If the hub, switch, or concentrator fails, nodes attached are disabled. *Requires more cable length than a bus topology. *More expensive than bus topologies because of the cost of the hubs, etc.
