All the Star Topology Questions and Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up their fundamentals on Star Topology.Digital communication deals with both wired and wireless networks using various networking devices such as Hubs, routers, Ethernet cables, and more. These devices are arranged in such a manner depending upon the topology and other consideration parameters. A wireless communication network can be designed flexibly depending on different network topologies available such as Star, Tree & Mesh topologies. A star topology also known as communication topology is a LAN network that connects each node in the network to a centralized hub.The main components involved in this star topology namely host, hub, and transmission lines. A hub on this network collects the data from the sender and distributes the same to other components on the network. Hence the hub component acts as a controller of the network. They benefit in terms of low latency between the hub and remote nodes. But lacks in terms of connection where if any one of the nodes gets disturbed or goes down the entire nodes on the same network gets disturbed. A star topology is mainly deployed in areas such as corporate offices, schools, and homes.1). A topology is considered from _____ of interconnections of circuits components?
