Updated on: October 17th, 2023

(a) Bus topology

(b) Ring topology

(c) Star topology

(d) Mesh topology

The topologies with the highest reliability is Mesh topology. The frequency of failure, the amount of time it takes for a link to recover from failure, and the robustness of the network are all used to gauge reliability. The physical configuration of a network is referred to as its topology.

Highest Reliability Topology

Mesh topology: Each device in this has a unique point-to-point connection to every other device. Dedicated refers to a link that exclusively transports traffic between the two connected devices. The best topology is this one.

Star topology: Each device in this has a unique point-to-point connection that is limited to the hub, a centralised controller. There is no direct connection between the devices. Direct communication between devices is not permitted. Every gadget just requires one link.

Bus topology: It has several points. The backbone of a network is made up of a single, lengthy connection that connects every device. Drop lines and taps are used to connect nodes to the bus cable.

Ring topology: Only two devices are present on either side of each device’s point-to-point connection in this scenario. From one device to the next in the ring, a signal is transmitted in a single direction until it reaches its target.

Summary:

Which of the following topologies gives highest reliability? (a) Bus topology (b) Ring topology (c) Star topology (d) Mesh topology

Mesh topology gives the highest reliability. It provides point-to-point connections to other devices. It transports traffic between the two connected devices. A topology is created when two or more devices connect to a link.
