Final answer:
In a bus topology, all devices on the network see each other's data traffic as data travels along the bus and is broadcast to all network devices. This differs from ring, star, and mesh topologies, where data is directed more selectively to its intended recipient.
Step-by-step explanation:
In the context of network topologies, the question pertains to which topology allows all devices on the network to see each other's data traffic. The correct answer to this question is b. Bus Topology. In a bus topology, each device is connected to a single central cable called the bus or backbone. As data is transmitted from one device, it travels along the bus and can be seen by all other devices on the network. This is because the bus topology broadcasts sent messages to all network devices, although only the intended recipient, defined by the MAC address, processes and takes the data.
Other topologies mentioned, such as ring, star, and mesh, operate differently. In a ring topology, data travels in one direction and passes through each device until it reaches its destination. A star topology has each device connected to a central hub, but the hub manages data traffic to ensure devices only see data meant for them. Finally, a mesh topology has a web-like structure with multiple paths, where each device might not see all traffic unless it's intended for them or part of a route they are facilitating.
