What does a cable modem connect to in order to access the internet?

A cable modem connects to a cable TV line to access the internet. This type of modem is specifically designed to utilize the same coaxial cable infrastructure that delivers cable television service to homes. By connecting to this line, the modem can receive data signals from the internet service provider and convert them into a format that can be used by computers and other devices in the home. This setup enables high-speed internet access through cable broadband, which is known for its relatively fast speeds compared to other forms of internet connectivity.

The other options represent different types of internet connections. A telephone line is typically used for DSL connections; a wireless router serves as a network device to distribute internet connections within a local area network; and a satellite dish is associated with satellite internet services, neither of which connects directly to a cable modem. Each option relates to different technologies for internet access, highlighting that the cable modem specifically requires a connection to the cable TV line for its functionality.
