The query requires identification of the cable utilized in a bus topology, characterized by its connection of multiple devices and the presence of terminators at its extremities to mitigate signal reflection. Let us examine the provided choices:
- Drop Line: A drop line is a subsidiary connection extending from a main line to an individual device. It lacks terminators and does not constitute the principal cable in a bus topology.
- Taps: Taps are junction points along a cable that facilitate the attachment of additional devices. Similar to drop lines, they are not equipped with terminators.
- Analog Cable: This designation lacks specificity within the context of networking topologies such as bus topology and is less pertinent regarding termination.
- Backbone: A backbone accurately represents the main cable in a network topology. In a bus topology, it functions as the central conduit linking numerous devices. Critically, the backbone is outfitted with terminators at both ends, a feature essential for preventing signal reflection (signal bounce) and ensuring optimal network functionality.
Consequently, the appropriate response is Backbone, as this cable type precisely matches the characteristics described in the question.
