In a logical bus topology, how do messages travel through the network?

1. Directly to the destination

2. Messages are sent to all devices

3. Messages do not travel

4. Through a central server

The correct answer is: Messages are sent to all devices

In a logical bus topology, messages travel by being sent to all devices on the network. This setup allows any device to send data that is broadcasted across the entire bus. When a message is transmitted, it travels along the bus and can be received by all connected devices. Each device then checks if the message is intended for it, and if so, it processes the data. This method of communication is efficient for small networks where devices share the same communication medium, but it can also create challenges in larger setups, including potential collisions and network congestion. In contrast to other topologies, such as star or ring, where messages may travel through specific pathways or to designated devices, a bus topology operates on a principle of broadcasting to all nodes, making option B the correct answer.
