"Wire" and "cable" are both terms used to describe a long, thin strand of material that is used to conduct electricity or transmit data. Wire is typically made of metal, such as copper or aluminum, while cable can be made of a variety of materials, including metal, plastic, and fiber optic. Power cables are used to transmit electricity, while control cables are used to transmit control signals. A portable cord is a type of electrical cable that is designed to be easily moved from one location to another, and is used for devices that need to be plugged into an outlet. A flexible cable is a type of electrical cable that is designed to be bent and twisted without breaking. Utility cable is a type of electrical cable that is used to transmit electricity over long distances. Copperweld cable and alumoweld cable are common utility cables. Electronic cable is used to transmit electrical signals in electronic devices. Multi-conductor cable and multi-pair cable are examples of electronic cable.
