Many DSL connections are broadband, but not all broadband is DSL. Broadband is a type of telecommunication that uses multiple data channels to send large volumes of information. The term broadband is an abbreviation of "broad bandwidth." Broadband internet services such as DSL and cable are considered to be high-bandwidth connections. Bandwidth is the amount of data that can be sent along a given channel per second.

There are three popular types of broadband Internet service: satellite, DSL and cable. Satellite Internet uses a satellite that's in orbit around the Earth to facilitate the transfer of data. DSL transfers data along unused bandwidth on ordinary telephone cable. Cable Internet uses a coaxial television cable to provide Internet service.

The slowest of all broadband services is DSL. It is also the least expensive service. It offers speeds up to 6 megabits per second (Mbps). Cable is faster, but it's less reliable and more expensive. Although cable Internet service providers often advertise download speeds up to 30 Mbps, cable users rarely achieve these speeds. Satellite is the most expensive of all commonly used broadband Internet services. Satellite speeds can range anywhere between 1 and 3 Mbps. The Federal Communications Commission now defines a broadband connection as having speeds of 768 Kbps. Therefore, not all DSL connections are considered broadband
