Broadband cable operators provide customers with HSD connections to the Internet through which standard?

Broadband cable operators utilize DOCSIS, which stands for Data Over Cable Service Interface Specification, to provide High-Speed Data (HSD) connections to the Internet. DOCSIS is a telecommunications standard that enables the transmission of data over existing cable television infrastructure. This standard allows cable companies to deliver internet services alongside traditional cable video services, ensuring efficient use of bandwidth and capacity on the network.

The DOCSIS standard supports various levels of data transmission speeds and is designed to optimize the performance and reliability of internet connectivity provided through coaxial cables. It also includes provisions for security, quality of service, and support for multiple users simultaneously sharing the network.

While other standards, such as Ethernet or DSL, have their own specific applications, they do not apply to the broadband cable operators' infrastructure in the same way that DOCSIS does. Ethernet is primarily used for local area networking rather than over a cable network, DSL is associated with digital subscriber lines over telephone networks, and IEEE 802.11 pertains to wireless networking protocols, which are distinct from cable-based connections. Thus, DOCSIS is the correct choice for broadband cable operators delivering high-speed internet.
