What is Moore's Law?

What will be an ideal response?

A long-term trend of rather remarkable regularity in the development of computer microprocessors has been observed since 1965. It is called Moore's Law after Intel co-founder Gordon Moore, who predicted in that year that the number of transistors on a chip would double approximately every two years. The number of transistors is a key determinant of how fast a computer processor is. Thus, Moore's Law implies that computer processor power should double approximately every two years. Several other measures of technological advances in computing have also behaved according to Moore's Law. For example, the number of pixels in digital cameras and RAM storage capacity has also doubled every two years or so, while power consumption of computer nodes and hard disc storage costs appear to have been halved approximately every two years.
