Quizplus · Accepted Answer

Coaxial cables are actually made up of two conductors, typically copper, that are separated by an insulating layer and then protected by an outer sheath. They transmit data as electrical signals. Fiber optic cables, on the other hand, are bundles of thin tubes of glass that transmit data as pulses of light.
