STAR TOPOLOGY




STAR

All computers and other devices on the network connect to a central device (hub/switch) thus forming a star

two types of devices that provide a common central connection point to all the network are a hub and a switch

How the data transmit:

In a star network,data, instructions and information's another node passes through hub/swith

1) If the network used hub, the signal will send to all nodes but only the intended recipient will accept the signal and the rest will ignore

2) If the network used switch, the signal will send directly to the intended recipient


Advantages of  Star  Topology

Disadvantages of  Star  Topology

If one device (pc/printer)  fails, only that device is affected
The network will be malfunctioned if the hub or switch break down
Devices (pc/printer) can be added or removed from network with little or no disruption
Requires more cable than most of other topologies
Easy to troubleshoot and isolate problem
