Broadband is a type of high-speed internet connection which has become one of the most used forms of Internet access because of its high speeds.
This definition of broadband is commonly used as a general description given to any high-speed internet access – broadband is actually used in many technologies and in telecommunications is defined as a wide bandwidth data transmission which can simultaneously transport multiple signals and traffic types.
With origins in physics, acoustics and radio systems engineering, the broadband term became popular in the 1990s when it was used as a marketing term for internet access which was faster than dial-up access.
Broadband, however, is a relative term. The broadband signal handles a wide band of frequencies, with the wider the bandwidth of channel, the greater the information-carrying capacity. For example, in radio a Morse code will be carried by a narrow band, while a broader band will carry speech, and an even broader band will carry music.
