A cable modem is a device that enables you to hook up your PC to a local cable TV line and receive data at about 1.5 Mbps.

Runs over the cable coax system
Send/receive over CATV wiring
Use FDM
Very high data rate, BUT:
Group of subscribers in neighborhood share bandwidth

Original cable system only had downstream capabilities
Amplifiers and such were only one direction
System had to be modified to handle two way data
Uses FDM. One frequency for a local neighborhood (usually over fiber)
Within neighborhood uses TDM

Cable Modem is basically a device which provides high speed internet connectivity via cable television company which serves as ISP.
Often, a cable company offering Internet service will provide a cable modem to the subscriber.
