A broadband Internet connection enables multiple data or information, video, image, audio or data signals of different frequencies to be transmitted simultaneously, at very high speed, to different network carriers. Broadband is like a tunnel with high capacity. There are different sub-tunnels, with each tunnel transmitting different information at a high speed. Each sub-tunnel is protected from any interference of disruption from the others. Distance doesn't affect connectivity, especially in wi-fi and satellite broadband connections.
The broadband Internet connection operates by using several different technologies or media. A traditional dial-up connection uses a telephone line and a modem. The information is converted into analog form, leading to less connectivity and speed. The telephone line cannot be used for normal phone calls when Internet is in use. A broadband Internet connection also uses an existing telephone line for a DSL connection. The information is transmitted using the digital broadband technology; hence, speed and connectivity is higher. The other types include cable broadband connections using existing cable lines, T1 and T3 satellite and wi-fi (wireless fidelity) connections. In case of cable or DSL connection, TV or telephone functioning remains unaffected.
