Also there is an exponential decline in the cost of transistors and rise in computing power. Packing more transistors into less space has driven down transistor cost dramatically as well as the cost of the products in which they are used. Moore’s Law • Since the first microprocessor chip was introduced in 1959, the number of components on a chip with the smallest manufacturing per component(transistors) had doubled every year Law of Mass digital Storage • The amount of digital information is roughly doubling every year. Fortunately the cost of storing digital info is falling at an exponent rate of 100 percent a year, doubling the amount of digital storage for each dollar. Declining communication costs and g...
