What network topology connects every device directly to every other device?

The correct answer is mesh topology, as it involves connecting every device directly to every other device in the network. This direct connection allows for high reliability and redundancy since if one link fails, the data can still be routed through other paths. Mesh topology is particularly beneficial in environments where continuous availability and fault tolerance are critical, as it provides multiple pathways for data to travel.

In contrast, star topology connects all devices to a central hub or switch, making the hub a single point of failure. Bus topology uses a single central cable (the bus) to which all devices are connected, and if that cable fails, the entire network can go down. Hybrid topology combines elements of two or more different topologies, but does not inherently connect every device to every other device as mesh does. Therefore, mesh topology is distinguished by its structure of complete interconnectivity among devices, enhancing the overall resilience of the network.
