A wire is a single strand of metal capable of transmitting power or data from one area to another. Wires are often protected in a plastic covering that is sometimes color-coded to aid in identification. The picture shows an example of a Cat 5 cable that was stripped to expose the wires. As shown in the image, a cable is composed of multiple wires.
A cable often has several wires.
