_____ technology is a broadband technology that can use the wires of a local telephone network.
Alenkasestr [34]
DSL  - DSL stands for Digital Subscriber Line. This technology came after the Dial Up technology for connecting to the Internet. The big disadvantage of Dial-up technology was that when you were talking on the phone, you could not use the Internet and vice-versa. However, although DSL technology used the regular telephone line , it worked on frequencies different from the telephone. So you could use the phone and the Internet at the same time.
