Answer: B - Digital Subscriber Line (DSL) is a type of high-speed connection technology that provides up to a 52-Mbsp transmissions speed without replacing the carrier’s copper wire. It can provide 6 to 30 times higher bandwidth speeds than ISDN and analog technologies. It uses existing phone line and provides a 24-hour connection to the Internet. However, both the carrier and the end user must have upgraded equipment for DSL. DSL provides faster transmission rates because it uses all of the available frequencies available on a voice-grade UTP line.
