What are the primary components of the DOCSIS architecture?

The primary components of the DOCSIS (Data Over Cable Service Interface Specification) architecture are indeed the cable modem and the cable modem termination system (CMTS). The cable modem serves as the device that connects the end user's home network to the broader cable network. It modulates and demodulates the data signals sent over coaxial cable, making it essential for digital communication over cable systems.

On the other end, the cable modem termination system, located at the service provider's facility, plays a crucial role in managing traffic between the cable network and the internet. It terminates the various connections from cable modems in the field and facilitates their communication with each other and with the internet. The interaction between these two components forms the backbone of DOCSIS technology, allowing for fast and reliable broadband internet service over existing cable television infrastructure.

The other options include components that relate to networking and broadband services more generally, but they do not specifically align with the DOCSIS architecture. Routers and switches are common in many networking environments, but they do not directly define the DOCSIS framework. Similarly, fiber optic cables and signal amplifiers are important in various telecommunication contexts, and home gateways and Wi-Fi routers are critical for user networking but are not the
