DSL vs. POTS

Traditional phone service (sometimes called POTS for “plain old telephone service”) connects your home or small business to a telephone company office over copper wires that are wound around each other and called twisted pairs. Traditional phone service was created to let you exchange voice information with other phone users and the type of signal used for this kind of transmission is called an analog signal.  Digital Subscriber Line is a technology that assumes digital data does not require change into analog form and back. Digital data is transmitted to your computer directly as digital data and this allows the phone company to use a much wider bandwidth for transmitting it to you.
