Moore's Law

Definition

Moore's Law is the observation that the number of transistors on a microchip doubles approximately every two years, leading to an exponential increase in computing power and a decrease in relative cost. This principle has been a driving force behind the rapid advancement of personal computing and the internet, enabling smaller, faster, and more efficient devices that have transformed how people interact with technology.
