Question

The network topology with highest reliability is

• A. Mesh topology
• B. Bus topology
• C. Star topology
• D. Ring topology

Hint:

Mesh topology provides the highest reliability because every device is connected to every other device, ensuring multiple paths for data transmission.

Answer 1

The Correct Option is A

- Mesh topology: In a mesh topology, each device is directly connected to every other device in the network. This provides high reliability because if one connection fails, there are multiple alternate paths for communication.
- Bus topology: In bus topology, all devices are connected to a single central cable (the bus). If the bus fails, the entire network can go down, making this topology less reliable.
- Star topology: In star topology, all devices are connected to a central hub. While it offers better reliability than bus topology, if the central hub fails, the entire network is affected.
- Ring topology: In ring topology, each device is connected to two other devices, forming a closed loop. While failure in a ring can sometimes be mitigated with token passing, the reliability is lower than mesh topology because the failure of any single link can affect the whole network.
Therefore, the correct answer is 1. Mesh topology.
