An electrical cable is an assembly of one or more wires running side by side or in bundle, which carries electric current.
A cable assembly is the composition of one or more electrical cables and their corresponding connectors. A cable assembly is not necessarily suitable for connecting two devices. But it is a partial product (e.g. to soldered onto a printed circuit board with a connector mounted to the housing). Cable assemblies can also take the form of a cable tree. Or cable harness design allows connecting many terminals together.
Ribbon Cable – Useful when many wires are required. This type of cable can easily flex. And also has good design to handle low-level voltages.
