DOCSIS stands for and its main purpose in cable networks?

• A. Digital Optical Communications Standards for Internet Service
• B. Data Over Cable Service Interface Specification
• C. Domain of Cable Services
• D. Data Over Coax System Interface Standard

Answer: (B)

The main idea here is a standardized way to carry data over the existing cable TV network. DOCSIS stands for Data Over Cable Service Interface Specification, and its purpose is to define the interface and protocols that let cable modems talk to the cable system’s headend equipment (the CMTS). This includes how data is modulated, framed, and transported over the coaxial network, enabling high-speed Internet over cable and ensuring interoperability between equipment from different vendors. The other descriptions don’t fit: one suggests optical technology, another is not a formal standard, and the last uses a wording that isn’t the official name of the specification.
