Broadband is a highspeed connection to the internet. The most common residential services are Cable, DSL (digital subsciber loop) and Satellite Internet. Broadband is defined as a higher throughput rate of bursty (data) traffic than is traditionally available on telephone company POTS (plain old telephone service) lines. Instead of dial-up internet service which uses a limited POTS line Broadband is an "always-on" direct connection which uses much higher capacity signaling. 

The Phone Company and the Cable providers continue to build-out their networks to be able to provide service to more and more rural areas. If you have a telephone number you can check for Broadband availability at your location. The database is driven by phone numbers, so if you don't have one you might try a neighbor's phone number to check availability.
