What does DOCSIS stand for?

The correct answer, Data Over Cable Service Interface Specification, is significant because it refers to a widely used standard that facilitates high-speed internet access via cable television (CATV) systems. DOCSIS defines the protocols for data transmission and ensures that different equipment, such as modems and network devices from various manufacturers, can communicate effectively over a cable network.

This standard has evolved through multiple versions, enhancing internet speeds and bandwidth capabilities, which is crucial for delivering modern high-speed internet services. It plays an essential role in ensuring consistent performance and compatibility in cable internet services, making it a key concept for technicians and anyone working in the field of telecommunications.

The other options listed do not accurately reflect industry terminology or standards related to cable internet technology, making them incorrect descriptions of DOCSIS. Understanding the correct definition not only helps in grasping the technical aspects of cable internet infrastructure but also aids in better communication within the industry.
