Cables are the medium that connect electronic devices together, while connectors are the physical interface between those devices. The most common type of cable is an electrical cable, which carries power or data between devices. Other types of cables include optical fiber and coaxial cable.
Connectors come in a variety of shapes and sizes, but all serve the same purpose: to join two cables together or to join a cable to an electronic device. The most common type of connector is the plug, which is inserted into an outlet or port. Other types of connectors include jacks, adapters, and terminal blocks.
