What is the arrangement of network devices in a mesh topology?

Rationale

Every device is connected to every other device.

In a mesh topology, each device is interconnected with every other device in the network, ensuring high redundancy and reliability. This arrangement allows for multiple pathways for data transmission, enhancing fault tolerance since the failure of one connection does not disrupt the entire network.

A (All devices are connected to a single central device) YOUR ANSWER

This describes a star topology, where all devices connect to a central hub or switch. In contrast, mesh topology lacks a single point of failure and does not rely on a central device for communication, making it fundamentally different in structure and operation.

B (Every device is connected to every other device) CORRECT

This is the defining characteristic of a mesh topology, enabling each device to communicate directly with all others. This interconnectedness provides a robust framework for data transmission, ensuring that multiple routes are available for information flow.

C (Every device is connected to exactly two other devices) YOUR ANSWER

This statement describes a linear or ring topology, where devices are connected in a sequence or loop. In a mesh topology, devices can connect to many others, not just two, allowing for greater flexibility and redundancy in communication paths.

D (Devices are connected to a common communication line) YOUR ANSWER

This represents a bus topology, where devices share a single communication channel. Unlike mesh topology, where each device has direct connections to every other device, bus topology limits communication to a single line, reducing redundancy and reliability.

Conclusion

Mesh topology is characterized by a complex interconnection where every device is linked to every other device, promoting high reliability and redundancy. This contrasts sharply with the structures described in the other options, which represent different topologies such as star, ring, and bus. Understanding these differences is crucial for designing resilient networks that can withstand individual device failures.
