Modems are no longer able to produce the speeds needed to download these web pages or play these games. There is a demand for a faster way to connect to and use the world wide web by both small companies and private users that cannot afford a T1 line. Digital Subscriber Lines and cable modems are two services that have come to fill that need. It is always connected, so no dial up is required. This service is brought fourth by the phone companies.
Cable modem is a service that goes through a cable TV connection.
It is also always connected and does not require a dial up. Cable television companies deliver this service. On the other hand, DSL providers will gain more revenue during the beginning stages of broadband Internet access services than cable modem providers, primarily because DSL providers can currently charge a premium for their business services. The proliferation of copper lines around the world has given the DSL modem a clear advantage over the cable modem. While copper phone lines are ubiquitous, cable is not.
