What is a cable modem network?
A cable modem network is the interconnection of many users using a cable television (CATV) network. Each user’s personal computer uses an Ethernet card to connect with a cable modem. The modem is then connected to a cable television outlet using a standard coaxial cable. On the street, the cables from various subscribers are connected together and eventually reach a facility of the CATV Internet Service Provider. A device at this facility, called a headend, manages communications over the cable network. The headend also sends signals to and receives signals from, the Internet.
