What is Star topology?
In constellation, all the elements of network ar connected to the central device observed as “hub” which may be a hub, a router or a switch. in distinction to constellation (discussed earlier), where nodes were connected to central cable, here all the workstations ar connected to central device with a point-to-point affiliation. so it should be aforesaid that every laptop computer is indirectly connected to every various node by the help of “hub”.
All the data on the constellation passes through the central device before reaching the meant destination. Hub acts as a junction to connect utterly completely different nodes gift in Star Network, and at identical time it manages and controls whole of the network. looking forward to that central device is utilized, “hub” can act as repeater or signal booster. Central device can also communicate with various hubs of assorted network. unprotected Twisted strive (UTP) coax is utilized to connect workstations to central node.

Advantages of Star topology
1) As compared to constellation it provides manner much better performance, signals don’t primarily get transmitted to any or all the workstations. A sent signal reaches the meant destination once passing through no over 3-4 devices and 2-3 links. Performance of the network depends on the potential of central hub.
2) easy to connect new nodes or devices. In constellation new nodes could also be adscititious merely whereas not moving remainder of the network. equally elements can also be removed merely.
3) Centralized management. It helps in observation the network.
4) Failure of one node or link doesn’t have a control on the rest of network. At identical time its easy to find the failure and troubleshoot it.
Disadvantages of Star topology
1) associate excessive quantity of dependency on central device has its own drawbacks. If it fails whole network goes down.
2) the utilization of hub, a router or a switch as central device can increase the worth of the network.
3) Performance and equally vary of nodes which could be adscititious in such topology is relied on capability of central device.
