Which of the following accurately describes a bus topology?

• A. All devices have a point-to-point connection
• B. All devices are connected by a single electrical circuit
• C. Devices are arranged in a circular format
• D. There is no central cable connecting devices

Answer: (B)

A bus topology is characterized by all devices being connected by a single electrical circuit, which is represented by a common backbone or cable. In this configuration, data packets are sent along the bus, and each device listens for messages intended for it. This design simplifies the network setup since it requires less cabling compared to other topologies, but it also means that if the main cable (the bus) is damaged, the entire network can go down. The other choices do not accurately reflect the nature of a bus topology. For example, having a point-to-point connection describes a different topology, where devices are directly linked to each other, rather than being connected through a single backbone. Arranging devices in a circular format refers to a ring topology, which operates differently from the linear structure of a bus. Lastly, stating that there is no central cable connecting devices contradicts the fundamental principle of a bus topology, which relies on a single cable as the core of the network structure. Thus, the most accurate description of a bus topology is that all devices are connected by a single electrical circuit.
