Q.2. You have been asked to wire a conference room with seven computers for a demonstration after a day. It needs to be done quickly and with lowest possible expenses. What network topology is best suited to this situation and why? Justify your answer with solid reasons?
Star Topology is the most common type of network topology that is used in homes and offices. In the Star Topology there is a central connection point called the hub which is a computer hub or sometimes just a switch. In a Star Network the best advantage is when there is a failure in cable then only one computer might get affected and not the entire network.
The Star Network Topology typically needs more cable to be networked than the usual Bus topology. A common cable that is used in Star Network is the UTP or the unshielded twisted pair cable. Another common cable that is used in star networks is the RJ45 or the Ethernet cables.
In a Star Network the entire network is dependant on the hub so if the entire network is not working then there could be a problem with the hub. This feature makes it easy to troubleshoot by offering a single point for error connection ad at the same time the dependency is also very high on that single point.
Star Topology Advantages
• A Star Network Topology is very easy to manage because of its simplicity in functionality.
• The problems can be easily located logically in a Star Topology and therefore is easy to troubleshoot also.
• The Star Topology is very simple in format so it is very easy to expand on the Star Topology.
