There's this insane invention called a Modulator-Demodulator, or "modem"
for short. It takes computer data and converts (modulates) it into tones
that can be transmitted over a standard telephone line, where it is then
converted back (demodulated) to the computer on the receiving end.
Current technology allows for transmission rates as high as 56,000 bps
(not to be confused with Baud).

Oh, and they put a man on the moon, too.
