What type of network technology uses DOCSIS?

The correct answer is that DOCSIS, which stands for Data Over Cable Service Interface Specification, is a technology specifically designed for delivering high-speed Internet access over existing cable television (CATV) infrastructure. This means that it enables Internet service providers to offer broadband Internet services using the same coaxial cables that deliver cable TV, allowing for efficient use of resources and infrastructure without the need for completely new wiring.

DOCSIS supports various types of broadband applications, enabling higher data transfer rates and improved performance for users. This technology has undergone several iterations, with each new version offering enhancements in speed, capacity, and efficiency, making it a fundamental component of many cable Internet service plans today.

Other network technologies mentioned, such as Wi-Fi, mobile data, and fiber optic communications, do not utilize DOCSIS. Wi-Fi networks operate wirelessly rather than through cable systems, mobile data transmission involves cellular networks that don't rely on cable infrastructure, and fiber optic communication uses light signals for data transmission through fiber optics rather than the cable systems defined by DOCSIS. Thus, understanding the specific application of DOCSIS in delivering Internet service through cable TV lines is crucial for differentiating it from these other technologies.
