what is the difference in dsl wireless router and regular router?

I need to know if there is a difference between a dsl wireless router and a regular wireless router. I see different ones. Some say dsl on them, some don't.

A DSL router is meant to use without a DSL modem. Essentially, if you buy a DSL router, you will not need to use the DSL modem that you use to connect to your Internet provider. The new DSL router will now connect you to your Internet provider as well as providing routing functions.GL

The DSL router includes a built-in modem, and the regular router doesn't. If you buy the regular router, you will also need to purchase a separate DSL modem.
