Final answer:
The discussion centers on a bus network topology using a backbone cable with terminators to prevent signal reflection, an older technology superseded by optical fiber communication with benefits like low loss, high bandwidth, and reduced crosstalk.
Step-by-step explanation:
The statement describes a network topology where all computers are connected to a single cable, known as a backbone, using T-connectors. To maintain signal integrity and avoid signal reflection issues, terminators are used at both ends of this backbone. This is characteristic of a bus topology, which was once common in networks. However, this technology has largely been replaced by more modern and efficient methods of networking, such as those utilizing optical fibers.
Optical fiber cables offer significant advantages over traditional copper wiring, such as low loss, which allows light to travel long distances without significant attenuation. This characteristic ensures that optical fibers can carry signals much further than copper cables before requiring amplification.
Another advantage is high bandwidth, which permits a greater number of conversations or data transfers simultaneously. The reduced susceptibility to electromagnetic interference results in reduced crosstalk between cables. Outside networking, optical fibers and the Law of Reflection are used in various applications such as corner reflectors on bicycles and binoculars, and to assess distances, such as the distance to the moon using reflectors left by astronauts.
