Which network topology consists of a single cable that connects devices in a straight line?

• A. Star.
• B. Bus.
• C. Ring.
• D. Mesh.

Answer: (B)

The correct answer is bus topology. In a bus topology, all devices are connected to a single central cable, which serves as the backbone for the entire network. Data travels along the cable in both directions, and devices can communicate with each other by sending data onto this single line. This type of configuration is simpler and requires less cabling than some other topologies, making it easier to set up in smaller networks. Bus topology can be advantageous due to its straightforward design and lower cost. However, it can also have limitations, such as difficulties in troubleshooting and a risk of network failure if the main cable is damaged. Understanding bus topology is crucial for anyone working with network configurations as it illustrates fundamental concepts of physical connections within a network.
