The difference between a cable and a wire

The unification of cables and wires is called wires and cables. There is no fixed and accurate distinction between wires and cables. Generally speaking, a wire is made of one or more conductors, such as copper and aluminum, which are twisted together. A cable is made up of one or more conductors, each of which is twisted together by one or more conductors, with a sheath around it. So simply put, each cable is the equivalent of a wire.
