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 in the network is directly connected to every other device, enabling robust communication and redundancy. This configuration ensures that if one connection fails, data can still be transmitted through alternative paths, enhancing network reliability.

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

This describes a star topology rather than a mesh topology. In a star configuration, all devices connect to a central hub or switch, which manages the network traffic. If the central device fails, the entire network can go down, which is contrary to the redundancy feature of a mesh topology.

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

This statement correctly defines a mesh topology. In this arrangement, each device has a dedicated link to every other device, facilitating direct communication and providing multiple pathways for data transmission, thus improving reliability and performance.

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

This describes a bus topology. In a bus topology, all devices share a single communication line or cable. This setup can lead to data collisions and is less reliable than a mesh topology since the failure of the main communication line can disrupt the entire network.

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

This describes a ring topology, where each device is connected to two others, forming a closed loop. In a ring topology, data travels in one direction around the loop, and a failure in one connection can disrupt the entire network, which is not the case in a mesh topology.

Conclusion

Mesh topology is characterized by the direct interconnection of all devices, providing enhanced reliability and redundancy. Each device communicates directly with every other device, which differentiates it from other topologies like star, bus, and ring. This unique arrangement allows for more flexible and resilient network designs, making it ideal for critical applications where uptime is essential.
