DSL stands for “digital subscriber line”, and it's the technology that enables you to connect to the Internet. It's a broadband technology, but it uses your phone line, so you can use your existing phone line. With DSL, you can have one telephone line, talking on that telephone line while you're connected to the Internet. The DSL modem will allow that connection to happen simultaneously, so you'll be always connected to the Internet 24 hours a day, whenever you want to get online, and it will not interrupt your phone service.
