Final answer:
Cable TV and cable internet using the same coaxial cable represent converged technology, allowing for multiple types of data transmission over a single medium. This has facilitated cheaper, faster, and better-quality data transmission, as well as the emergence of spin-off technologies. The telecom industry has evolved from monopolies to shared transmission systems, changing our understanding of utilities.
Step-by-step explanation:
Since cable TV and cable internet can share the same coaxial cable, they are considered to be a form of converged technology. Coaxial cables consist of two concentric conductors separated by insulation, as seen in Figure 9.18, making them suitable for transmitting multiple signals simultaneously. This is possible because of the way cable networks operate: unlike traditional broadcasting that requires local affiliates for airwave transmission, cable networks send signals to homes directly through coaxial or fiber optic cables, purchasing broadcasting rights for the stations their viewers prefer.
This type of technology has had profound effects on the telecommunications landscape. Transitioning from aerial signals to cable and fiber optics has allowed for cheaper, faster, and better-quality data transmission. The rise of spin-off technologies like free Internet-based calling and video calling are evidence of the advancements made possible by this shift. Moreover, as technology has evolved, so has the definition of what we consider to be utilities, moving away from a single company monopolizing a service to multiple firms using shared transmission mechanisms, as was the case with AT&T losing its monopoly over long-distance service.
