A network is set up with a single communication line where all devices share the same transmission medium. Which topology does this describe?

Rationale

Bus topology describes a network with a single communication line where all devices share the same transmission medium.

In a bus topology, all devices are connected to a single central cable, known as the bus, which acts as the shared communication line. This setup allows all devices to listen and transmit data over the same medium, making it a simple and cost-effective network configuration.

A (Bus) CORRECT

This is the correct answer as a bus topology allows multiple devices to communicate over a single transmission medium. Each device is connected to the bus, and when one device sends a signal, it travels along the bus and can be received by all other devices connected to it.

B (Hybrid) YOUR ANSWER

A hybrid topology combines two or more different types of topologies (e.g., star and bus) to form a more complex network structure. While it can accommodate various configurations, it does not specifically refer to a single communication line shared by all devices, which is characteristic of bus topology.

C (Tree) YOUR ANSWER

Tree topology is a hierarchical structure that resembles a branching tree, where multiple star topologies are connected to a central bus. Though it allows for multiple connections, it does not entail a single communication line shared by all devices, making it distinct from a bus topology.

D (Star) YOUR ANSWER

In a star topology, all devices connect to a central hub or switch, which acts as a mediator for communication. This configuration relies on multiple connections rather than a single shared medium, differentiating it from the bus topology where devices directly share one communication line.

Conclusion

Bus topology is characterized by a single communication line that connects all devices, allowing them to share the same transmission medium. This distinguishes it from hybrid, tree, and star topologies, which involve more complex arrangements and do not feature a singular communication line for all devices. Understanding these distinctions is crucial for selecting the appropriate network topology based on specific needs and constraints.
