what is broadband internet

broadband :

 1.High-speed transmission. The term is commonly used to refer to Internet access via cable modems or DSL, which is faster than dial-up. For years, "broadband" has referred to a higher-speed connection, but the actual speed threshold has varied. While T1 (1.5 Mbps) has been widely used as the threshold, others have used T3 (45 Mbps) for broadband. For example, after the turn of the century, South Korea leapfrogged the U.S. in Internet access, offering DSL up to 50 Mbps and calling their 1.5 Mbps service "light." In every case, however, it implies transmitting at higher speeds.
 2.A method of transmitting data, voice and video using frequency division multiplexing (FDM), such as used with cable TV. Modems are required to modulate digital data streams onto the line. Broadband in this context is used in contrast with "baseband," which is all digital transmission and uses time division multiplexing (TDM). However, the term is mostly used as defined in definition #1 above.
