What is Cable Internet

Today different broadband solutions are available to provide the high speed internet connectivity and to meet the unique business requirements.  The common broadband solutions are DLS, Satellite Internet and Cable internet.  Cable modems are used to provide the high speed broadband internet access by using the existing coaxial cable.  Cable modem has been specifically designed to operate over the coaxial cable television lines.  Cable internet provides the facility to watch TV and use internet at the same time. Cable modems can offer speed up to 2Mbps, which is more than the dial-up connections but less than the DSL, which supports up to 9Mbps.

Cable internet can also be used to provide the IP telephony and the VOIP services.  There are almost millions of the subscribers of the cable internet in the USA, Europe, Australia and the rest of the world.  In the network topology, a cable modem acts as a network bridge that connects your Ethernet based network with your local ISP.  In the networks, the cable modem is usually attached with the gateway computer that is assigned a fixed IP address from the local ISP.

A coaxial cable directly from the ISP is connected with the cable modem and the modem is connected with the computer through the Ethernet or USB ports.  Data is transmitted between the computer and the cable modem at 10Mbps.  Like the DSL and other broadband internet connectivity, Cable internet also has some pros and cons, which have been discussed below.
