I'm not an electrician, so I can't tell you the technical answer, but the simple answer is 2-conductor wire has two insulated wires plus a bare ground wire (for hot-hot for 220v or hot-neutral for 110v), and 3-conductor wire has three insualted wires plus bare ground (for 3-way switches, power for 220v and 110v for hot-hot-neutral to a subpanel such as in a boathouse, etc.). At least that's my wiring use.
I'm sure that the pros here can give you a lot more info.

You said it well enough old guy! 12-2 romex will have a black, a white, and a bare copper conductor. 12-3 will have a red, a white, a black, and a bare copper conductor.
