What does DOCSIS stand for?

The correct answer, "Data Over Cable Service Interface Specifications," refers to the set of technical standards used to provide internet access via cable television systems. DOCSIS is crucial in enabling high-speed data transfer over existing cable networks, allowing cable service providers to offer internet services to their customers. This standard ensures compatibility between equipment from different manufacturers and allows for efficient data transmission by defining how data packets are sent and received over the cable infrastructure.

The other options, while they might mention similar concepts, do not accurately represent the correct terminology or the established definition of the standard. The correct wording captures the essential elements of the technology that is widely recognized in the telecommunications industry, reflecting both its purpose (data transmission) and medium (cable service interface). Understanding DOCSIS is fundamental for technicians working with cable internet services, as it underpins how data is delivered across these networks.
