What is the primary use of DOCSIS technology?

DOCSIS technology, which stands for Data Over Cable Service Interface Specification, is a standard used primarily to enable high-speed internet access through existing cable television infrastructures. Its main function is to facilitate the transmission of data over coaxial cable networks, allowing internet service providers to deliver broadband services using the same lines that supply cable TV.

This technology enables multiple services to coexist on the same line, such as television and internet, meaning it efficiently utilizes the existing cable infrastructure. DOCSIS outlines how data should be transmitted, ensuring compatibility and performance standards that allow for reliable and fast internet connections for residential and commercial customers.

The other options relate to network technologies but do not correctly describe the primary purpose of DOCSIS. For instance, enhancing LANs involves different networking protocols and technologies that manage local connectivity rather than cable internet. Similarly, securing wireless traffic pertains to wireless technologies and encryption methods rather than cable standards. Finally, connecting VPNs involves creating secure tunnels over the internet, which is distinct from the scope of DOCSIS technology.
