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

Rationale

Every device is connected to every other device.

In a mesh network, each device is directly connected to every other device in the network. This interconnected structure provides redundancy and multiple paths for data transmission, enhancing network reliability and fault tolerance.

A (Every device is connected to every other device.) CORRECT

This choice correctly describes the arrangement in a mesh network, where each device has a direct connection to all other devices. This setup allows for robust communication and ensures that if one connection fails, alternative pathways are available for data transmission.

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

This option describes a bus network, where devices are connected to a central communication line. In a bus network, data is transmitted along this shared line, and devices can read the information passing by to determine if it is intended for them.

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

This scenario matches a ring network configuration, where each device is connected to precisely two other devices, forming a closed loop. Data travels in one direction around the ring, and each device regenerates and forwards the signal to the next device until it reaches the intended recipient.

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

This setup corresponds to a star network, where all devices are connected to a central hub or switch. In a star network, communication between devices must pass through the central hub, making it a critical point of failure and potentially causing network congestion.

Conclusion

In a mesh network, the arrangement ensures that every device is interconnected with every other device directly, creating a robust and fault-tolerant network structure. This design allows for efficient data transmission, redundancy, and flexibility in routing, making mesh topologies ideal for applications requiring high reliability and scalability.
