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

Rationale

Every device connected to every other device.

In a mesh topology, each network device is directly connected to every other device, creating multiple paths for data to travel. This arrangement enhances redundancy and reliability, as the failure of one connection does not disrupt the overall network.

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

This describes a star topology, where all devices are linked to a central hub or switch. In contrast to mesh topology, star topology relies on the central device for data transmission, making it less fault-tolerant since the failure of the central device can disrupt the entire network.

B (Every device connected to every other device) CORRECT

This is the correct definition of a mesh topology. In this configuration, every device has a dedicated point-to-point connection with every other device, allowing for direct communication and multiple pathways for data, which enhances network resilience.

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

This arrangement characterizes a ring topology, where each device connects to two others, forming a circular data path. In contrast, mesh topology requires all devices to connect to every other device, providing greater flexibility and reliability.

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

This describes a bus topology, where all devices share a single communication line for data transmission. This setup contrasts with mesh topology, where each device has its own dedicated connections, contributing to a more robust network.

Conclusion

A mesh topology is defined by the direct interconnection of all devices, allowing for enhanced communication and network reliability. This contrasts with other topologies like star, ring, and bus, which utilize different connection methodologies and exhibit varying levels of fault tolerance and redundancy. Understanding these distinctions is crucial for designing resilient network infrastructures.
