Fiber Optics
A technology that will soon replace telephone wires. Fiber optic cables have fishing line type threads, (or fibers), that carry data in the form of light beams. This data travels at the speed of light. It not only is much faster than wired transmission, it is also capable of digital transmission and can carry much more data. Digital data is the natural form of data used by computers.
