Question 17

Bus Topology describes a network with a single communication line shared by all devices.

In a bus topology, all devices are connected to a single central cable, known as the bus, allowing them to communicate over the same transmission medium.

A) Bus

This option is correct because a bus topology is characterized by a single communication line that all devices share. In this setup, signals are transmitted along the bus and can be received by all connected devices, illustrating how a shared transmission medium functions.

B) Hybrid

A hybrid topology combines elements of different types of topologies, such as star and bus. It does not fit the description provided, as it involves multiple communication lines and structures rather than a single shared medium.

C) Tree

A tree topology is a variation that combines characteristics of star and bus topologies, featuring hierarchical connections. This option is incorrect because it does not represent a single communication line shared by all devices, but rather a branching structure.

D) Star

In a star topology, each device is connected to a central hub or switch, which acts as a mediator for communication. This option is incorrect as it describes a network configuration with multiple communication lines radiating from a central point, rather than the single line described in the question.

Conclusion

Bus topology is definitively the correct answer as it specifically describes a network arrangement where all devices share a single communication line. The other options do not align with the characteristics of a shared transmission medium, as they involve more complex structures and multiple connections.
