What does BX cable mean?

BX Cable and Wiring Basics Going under alternative names such as metallic sheathedcable, type AC, MC, Greenfield, or armored cable,BX cable is a collection of plastic-coated insulated wires(typically 14- or 12-gauge), bundled together and protected by aribbon-like metal sheathing.
