Modem

/ˈmoʊdɛm/ noun

Definition

A modem is a device that connects a computer or network to the internet by converting digital data into signals that can travel over phone lines, cables, or other systems, and back again. It acts as a translator between your home network and your internet provider.

Etymology

Shortened from “modulator-demodulator.” It describes the device’s job of modulating (changing) and demodulating signals so they can move across communication lines.

Kelly Says

The ‘modem’ name hides its whole job in plain sight: it both shapes signals and then un-shapes them. Even with fiber and Wi‑Fi, that basic translate-and-retranslate dance is still what lets your memes cross the planet.
