DSL may refer to any of the following:

1. Short for digital subscriber line, DSL is a method for home users and small businesses to have high-speed access to the Internet over standard copper lines. Capable of receiving up to 6.1 megabits per second, DSL is a great broadband solution if it's available in your area. Because of the technology used, DSL's availability depends on the user being within a certain distance from your phone company's CO (central office).


DSL is often one of the slowest broadband solutions. We often only recommend DSL if no faster broadband options are available or other options are too expensive.

3. Short for domain-specific language, DSL is a language designed for a specific purpose. See our general-purpose language page for further information about these types of languages.
