MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Star topology has become the dominant physical topology for LANs. The star was first popularized by ARCNET, and later adopted by Ethernet. Each node is connected directly to a central device such as a hub or a switch, as shown in Figure 5.17.

Detailed explanation-2: -Star topology is the most popular network topology in businesses today. Bus topology is one which consists of all of the workstations connected to a single cable.

Detailed explanation-3: -Star topology gives much better performance because signals don’t necessarily get transmitted to all the workstations connected to the network. In a bus topology, any computer that is connected to a network will be able to see all the data transmissions on all the other computers. So there are no chances of security.

Detailed explanation-4: -Due to its simple structure, Star topology is less complex as compared to Ring Topology. Conversely, ring Topology is considered more complicated due to the increased complexity in node arrangement. Star Topology is cost-efficient as compared to Ring Topology.

Detailed explanation-5: -Star topology is a type of network topology in which every device in the network is individually connected to a central node, known as the switch or hub. When represented visually, this topology resembles a star which gives it its name.
