telephone line.
Dialup Telephone: Typically has very low bandwidth
Satellite: Not suited for heavily wooded areas.
Cable: Uses coaxial cable as medium

DSL is an always-on, high bandwidth connection that runs over telephone lines. Cable
uses the same coaxial cable that carries television signals into the home to deliver
Internet access. Dialup telephone is much slower than either DSL or cable but is the
