The contributions of the transistor technology and how it has impacted the world cannot be overstated. The potential of solid state electronics was consequential in the break up of the telephone monopoly, the merging of communications and computing, the recent restructuring of industry, and increasing availability of advanced services and electronic commerce. Solid state electronics was instrumental in the winning of the cold war. The economic power of solid state electronics was an undisputable edge for Japan and the West. Japan and Silicon Valley had become the envy of the modern world. (Joh
The invention of the telephone is considered to be the beginning of the “Information Age”. About fifty years ago it became clear that the technologies providing telecommunications were unable to support the growing demand. At this time telecommunication technologies were based on wire and vacuum tubes. The vacuum tubes cathode required a good amount of heat in order to boil out electrons. In addition, the vacuum tubes often burned out and were fragile and bulky. Large amounts of wire were needed in order to run the telecommunications system of the time. This wire proved to be extremely difficu
