Question 25

Every device is connected to every other device in a mesh topology.

In a mesh topology, each device is interconnected with every other device, ensuring multiple paths for data transmission and enhancing redundancy.

A) All devices connected to a single central device

This describes a star topology, not a mesh topology. In a star topology, all devices connect to a central hub or switch, which acts as a conduit for data transmission among the devices. This structure does not provide the direct interconnection characteristic of a mesh topology.

B) Every device connected to every other device

This is the defining feature of a mesh topology. It allows for robust communication between devices, as each device can send and receive data directly to and from other devices without relying on a central hub. This arrangement enhances redundancy and reliability within the network.

C) Every device connected to exactly two other devices

This describes a linear or ring topology, where devices form a chain or loop. In such a setup, each device connects to two others, which limits the direct communication paths available and does not reflect the interconnected nature of a mesh topology.

D) Devices connected to a common communication line

This option refers to a bus topology, where all devices share a single communication line. In this topology, devices transmit data over the same medium, which can lead to collisions and reduced performance, contrasting with the multiple connections found in a mesh topology.

Conclusion

The correct answer is option B, as it accurately describes how devices are arranged in a mesh topology, with every device directly connected to every other device. Options A, C, and D do not represent the characteristics of a mesh topology, highlighting the distinct nature of this network arrangement.
