Cable Modems


Untitled Document A cable modem typically connects a cable wall hookup to a PC's 10BASE-T Ethernet card. Utilizing an always-on connection, cable modems transfer data across local cable TV lines, toggling between analog and digital signals. With data transfer rates comparable to DSL, cable modems (1.5 - 2.5 Mbps) are considerably faster than dial-up modems (28.8 - 56 Kbps) and ISDN (128 Kbps).
