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 significantly impacted the evolution of electrical engineering and technology, driving innovation in semiconductor design, computer architecture, and overall system performance.
