B (Q.12of 6) The letter can be used once only

On the horizon are optical computers These could store programs and process information by means of light – pulses from tiny lasers – rather than electrons And the pulses would travel over glass fibers, not copper wire These machines could function hundreds of times faster than today’s electronic computers and hold vastly more information Today fiber optics are used to obtain a clearer image of smaller and smaller objects than ever before – even bacterial 81 viruses. A new generation of optical instruments is emerging that can provide detailed imaging of the inner workings of cells. It is the surge in fiber optic use and in liquid crystal displays that have set the U.S. glass industry (a 16 billion dollar business employing some 150,000 workers) to building new plants to meet demand.
