In which topology do devices form a closed loop, with data traveling in one direction?

The correct answer is C, Ring Topology, as it is characterized by a closed loop configuration of devices. In a ring topology, each device is connected to exactly two other devices, with the last device connecting back to the first, thus forming a continuous circle or loop. Data travels around the ring in a unidirectional manner, meaning that the information is sent in one direction from one device to the next until it reaches its destination.

This structure can help to efficiently manage data transmission and reduce the chances of data collisions, as each device gets the opportunity to receive data in its turn. The design inherently allows for easier identification of faults by isolating particular segments of the network, though if one device goes down, it can disrupt the entire network unless there are redundancy measures in place.

Understanding this specific configuration of ring topology clarifies why it is distinct from other topologies. For example, star topology utilizes a central hub to connect all devices, while bus topology involves a single cable where devices connect at various points along its length, allowing bidirectional communication without a loop structure. Meanwhile, mesh topology provides connections in a web-like manner, which can be either fully interconnected or partially, accommodating multiple paths for data to take, thus differing fundamentally from the simplicity
