DSL
Digital Subscriber Line.
A telephone line that carries
both voice and data signals; it
allows you to talk on the phone
and browse the Internet at the
same time. The data part of the

connected to the Internet, allows
high-speed, high-capacity data
transfer. Your local telephone
company provides the necessary
equipment—a DSL modem, a
network interface card, and a
splitter.
