Computer Networking, a technological arena where bunch of computer systems and resources are gets connected for the ultimate end to provide a stage of communication and sharing. While Topology a set of rules and guidelines how these bunch of computer systems and devices will be attached with each other and will take part in communication. IT Support firms, for instance, Pro Link Systems, stating many set of rules and guidelines need to established such and other sorts of network setup, but in spite of this we will merely get bonding with star computer networking topology for this unique moment. In a star topology, each of the network node has a direct dedicated connection with the central device named Hub. This dedicated connection makes the star topology really reliable for the reason if the certain link is get damaged so it will merely effect the concerned node rather the entire network setup.
Considering the prior tribute tale to star topology, we can judge that it would be an expensive topology, no doubt, for the reason that it requires each node to have a direct connection with the central hub for access. But things are not going in the same way, in this technological pace, we are stepping forward to the stage to get most out of a simple thing. The traditional star topology is customized to get the same level of output, even better than that, with less investment or input you could also say. The newly customized star topology is termed as Extended Star Topology, where there groups are created and maintained. Each group has a direct connection with the hub via a dedicated link while each group has got its own subordinates directly attached with it and indirectly connected with the central hub. Whenever, a subordinate in a group willing to have communication with a node lied in a other group, so initially the sender request will be go through its associated group to central hub, thereafter hub will re-transmit the signals towards the group where the correspondent recipient lying.
