Hans is correct; a DSL modem is a modem. A cable modem is also a
modem. Here's why: Modem stands for MODulate-DEModulate, and
modulation is the process of changing the frequency, amplitude, and
phase of an analog signal in order to encode a digital signal. Both
DSL and Cable internet are digital information carried through an
analog medium, so a modem is required on both ends. I believe ISDN,
on the other hand, is transmitted digitally, as are most network
protocols that go over twisted pair or fiber.
