Broadband (delivered through a Digital Subscriber Line [DSL]) is generally applied to telecommunications in which a wide range of frequencies is available for transmission of data, typically voice and data together. So broadband provides an always-on connection, allowing home user to access the Internet while still being able to use the telephone. Clearly this is more efficient than using a dial-up connection, which makes exclusive use of a telephone line. In addition, broadband typically also provides a faster connection, of 512Kbps, 1Mbps, 2Mbps or more.
