Quizplus · Accepted Answer

DSL, or digital subscriber line, works by sending high frequency signals that are inaudible to humans over existing telephone lines. This allows the telephone line to carry both voice and data simultaneously, without interfering with each other. The DSL modem at the user's home filters out the voice signals and converts the digital data into a format that the home computer can use.
