In 1965, Gordon Moore, one of the pioneers of integrated circuits, predicted that the number of transistors that could be fit on one chip would double every year. In 1975, he revised his estimate to doubling every two years. This prediction is known as Moore's Law.
It turns out that other important measurements have also shown roughly the same doubling behavior, such as processor speed and the amount of memory that fits in a computer. Doubling hardware speed improves the size of problems that you can efficiently handle.
The importance of Moore's Law isn't just that computers get bigger and faster over time; it's that engineers can predict how much bigger and faster, which helps them plan the software and hardware development projects to start today, for use five years from now.
