Empirical observation by Gordon E. Moore, co-founder of Intel, that, over the history of computing hardware, the number of transistors on integrated circuits doubles approximately every two years.
Note: Moore’s law applies more fundamentally to advances in lithographic processing, particularly achievable resolution, since the inception of printed circuit boards.
