Q36: What is a Star Topology?
A36:With a star topology,each station has a cable connecting back to
a central hub. The most popular networks using a star topology are 10BASE-T
Ethernet and Token Ring. Basically every cable is required to begin in
a central distribution room and end at its respected jack location no
longer than 300ft away.
Advantages: A star can simplify troubleshooting because stations can
be disconnected from the hub one at a time until the problem is isolated.
Further, some hubs are equipped with LEDs that can indicate activity and
errors on each port,making it even easier to isolate problems. Disadvantages:
It requires more cable to wire a star. A hub failure can knock out the
entire network.Stars can be more expensive because of the cost of the
hub.
