Gordon Moore, the cofounder of Intel, made a prediction in 1975 that is now known as Moore’s Law. He predicted that the number of transistors on a computer processor at a given price point would double every two years. In October 1985, a specific processor had 275,000 transistors. About how many years later would you expect a processor at the same price to have about 4.4 million transistors?
