What is the difference between Cable Modem and ADSL Modem?

Answer 1

A cable modem is a rather broad term and may vary in technical specification depending on supplier. In general cables modems connect to a dedicated cable and offer internet services, possibly along side a cable TV service.

ADSL is a specific technology used to deliver high speed data services on an existing telephone line. The internet service is sent at specific frequencies and are filtered by the ADSL modem.

If you are looking to buy a modem you need to find out what type you need. The best way to do this is to call your ISP.
