MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -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.

Detailed explanation-2: -The star topology utilises the switch or central hub for broadcasting data and info to all the devices present in a network. On the other hand, the bus topology utilises just a single cable that connects all the peripheral devices.

Detailed explanation-3: -Advantages of a Linear Bus Topology Requires less cable length than a star topology.

Detailed explanation-4: -Mesh Topology Each node is connected to every other mode with a direct link. This topology creates a very reliable network, but requires a large amount of cable and is difficult to administer.

Detailed explanation-5: -Stars feature better fault tolerance: any single local cable cut or NIC failure affects one node only. Since each node is wired back to a central point, more cable is required as opposed to bus (where one cable run connects nodes to each other).
