—You can connect your computer to the internet through wifi or ethernet.
—What's the difference?
—One goes through air and the other through a wire.
—Ok, so "ether" means air, so ethernet must be the one that goes through the air. And I guess the "wi" in "wifi" stands for wires.
—Nope, "wi" stands for wireless, and "ether" doesn't stand for anything.
