What does a cable modem provide?

A cable modem is a device that connects a home or business network to the internet via a cable television infrastructure. When considering the capabilities of a cable modem, it primarily serves to provide a consistently connected internet service. This connection allows users to access the internet continuously as long as the modem is powered on and has a healthy signal from the cable provider.

Cable modems facilitate high-speed data transmission, enabling users to utilize the internet for various tasks such as streaming, browsing, or online gaming without significant interruptions. The emphasis here is on the reliable and stable connection that a cable modem offers, which is essential for seamless internet usage.

This differentiates it from the other options. For instance, intermittent internet service would fail to meet the requirements of most internet users, and while some cable modems can provide wireless access, the primary function is to establish a steadfast internet connection through a wired cable service. Additionally, cable modems do transmit internet data rather than only television signals, which is associated with cable boxes or digital receivers. Thus, the answer that highlights the cable modem's role in providing a consistently connected internet service stands out as the most accurate.
