Definition Edit

A cable modem is a hardware device that allows a computer to access the Internet through a cable system at much high speeds than through the traditional telephone modems.

Overview Edit

Most cable modems are external devices that have two connections, one to the cable wall outlet and the other to a computer or router.

Cable modem service enables cable operators to provide broadband using the same coaxial cables that deliver pictures and sound to the TV set. Although the speed of service varies with many factors, including the type of cable modem, cable network, and traffic load, download speeds of up to 6 Mbps are typical. Cable providers are developing even higher-speed services.

Subscribers can access cable modem service simply by turning on their computer without dialing-up an ISP. They can still watch cable TV while using it.

A cable modem performs all network-specific functions. It also connects via a standardized Ethernet port to numerous devices consumers can buy, including PCs, game consoles, digital media devices and wireless routers.
