Which of the following statements are true about topologies in computer networks?

A. Star topology relies on a central hub for communication.

B. Mesh topology eliminates the need for a central node.

C. Bus topology is most fault tolerate topology.

D. Ring topology connects devices in a closed loop.

E. Tree topology is a hierarchical topology where multiple star networks are connected with central hub.

Choose the most appropriate answer from the options given below:

The Correct answer is A, B, D, and E only.

Key Points

• Star topology relies on a central hub for communication.
  • True. In a star topology, all devices are connected to a central hub or switch, which facilitates communication between them.
• Mesh topology eliminates the need for a central node.
  • True. In a mesh topology, each device is connected to every other device, so there is no central node needed for communication.
• Bus topology is most fault-tolerant topology.
  • False. Bus topology is actually less fault-tolerant. If the main cable (bus) fails, the entire network goes down. It is not the most fault-tolerant topology.
• Ring topology connects devices in a closed loop.
  • True. In a ring topology, each device is connected to two other devices, forming a closed loop for communication.
• Tree topology is a hierarchical topology where multiple star networks are connected with a central hub.
  • True. Tree topology is a combination of star and bus topologies, where multiple star-configured networks are connected in a hierarchical manner.

Additional Information

• A network topology refers to the arrangement of devices in a network, detailing how they are connected and communicate.
