NM Cable. NM cable stands for nonmetallic cable and is a fully self-contained electrical wiring product. The cable often has 3 wires (positive, neutral and ground) inside a hard plastic or rubber sheathing. It is relatively inexpensive and is extremely easy to work with.
Coaxial cable is called coaxial because it includes one physical channel that carries the signal surrounded (after a layer of insulation) by another concentric physical channel, both running along the same axis. The outer channel serves as a ground.
