MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -The star topology is the most common network topology used nowadays for the many advantages it provides. This topology requires a centralized unit, which is called a switch, and all other network devices are connected to this switch with own network cable.

Detailed explanation-2: -Star topology is by far the most common. Within this framework, each node is independently connected to a central hub via a physical cable-thus creating a star-like shape. All data must travel through the central node before it reaches its destination.

Detailed explanation-3: -In networks with ring topology, computers are connected to each other in a circular format. Every device in the network will have two neighbors and no more or no less. Ring topologies were commonly used in the past but you would be hard-pressed to find an enterprise still using them today.

Detailed explanation-4: -Ring/Collapsed ring topology: In this topology, all the devices are connected to each other using a single cable like the Bus, but the two ends remain connected to each other, so that if a device went down, it is still possible for other devices to remain connected.

Detailed explanation-5: -Ring topology is a type of network topology in which each device is connected to two other devices on either side via an RJ-45 cable or coaxial cable. This forms a circular ring of connected devices which gives it its name. Data is commonly transferred in one direction along the ring, known as a unidirectional ring.
