Modems are used for cable based internet connections as well.

More about modems: The typical modem from years back was capable of dial-up internet access only. Now technology has advanced and has incorporated modems for use with cable internet providers. The motorola modem is not a wireless modem and is most commonly used with regard to cable internet connections because of its security features, ease of transferability, and end user satisfaction. It is extremely easy to set-up. The television cable cord from the wall connects directly to the back of the modem and the ethernet or USB connects directly from the modem to the computer. Once the power cord is set-up the modem can be turned on and is ready to go. The easy read out on the side display lets the user know it is working and there is a stand-by button on top that can be pressed to disconnect the PC from the modem without actually disconnecting the cable from the modem. This wireless modem is used by many cable companies to provide internet service and typically is free with service. It provides fast, reliable, and easy internet access.
