Imagine light traveling through tiny glass tubes like super-fast highways. 'Fiber-optic' describes technology that uses thin strands of glass or plastic to transmit data as light signals. It's way faster than traditional copper wires β‘. Fiber-optic cables are used for internet, phone calls, and even medical imaging. Think of it as the nervous system of the internet π, carrying information at incredible speeds. It allows for high bandwidth and minimal signal loss.
