A star takes more cable than e.g. a bus, but the benefit is that if a cable fails, just one node is going to be brought down. Each device within the network is connected to a central device called a hub. If one device wants to send data to another device, it’s to first send the info to the hub then the hub transmits that data to the designated device. The number of links required to connect nodes in the star topology is N where N is the number of nodes.  Advantages of Star Topology
Disadvantages of Star Topology
What Does Star Topology Mean?Star topology is a network topology in which each network component is physically connected to a central node such as a router, hub or switch. In a star topology, the central hub acts like a server and the connecting nodes act like clients. When the central node receives a packet from a connecting node, it can pass the packet on to other nodes in the network. A star topology is also known as a star network. Techopedia Explains Star TopologyStar networks require a point-to-point connection between the central node and connecting devices. To improve communication between the devices on the network, the central node can provide signal reconditioning and amplification services. Star topologies are often used in home networks. The benefits of a star network topology include the following:
This article lists 100 Star Topology MCQs for engineering students. 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?
