Which of the following is an application of DOCSIS technology?

DOCSIS, which stands for Data Over Cable Service Interface Specification, is a standard used to provide high-speed internet access over existing cable television infrastructure. This technology allows for the transmission of data packets over coaxial cable, enabling internet service providers to offer broadband services to consumers.

The application of DOCSIS technology involves using the cable system's capacity to support internet traffic, which includes capabilities for high bandwidth, allowing for faster data transfer rates compared to traditional methods. With DOCSIS, cable operators can deliver internet services that support a range of applications, from basic browsing to streaming high-definition video.

While other options like analog signal processing, digital television broadcasting, and voice over IP services may utilize different technologies, they do not specifically stem from the DOCSIS framework focused on enhancing data communications over cable networks. Thus, high-speed internet access is the primary application of DOCSIS technology, highlighting its role in modern broadband connectivity.
