Which law states transistor counts double roughly every 18 months?

• A. Moore's Law
• B. Newton's Law
• C. Hooke's Law
• D. Avogadro's Law

Answer: (A)

Moore's Law describes a trend in chip technology where transistor counts on integrated circuits double roughly every 18 months. Named after Gordon Moore, the observation—originally predicting about a doubling each year—became a guideline that has driven hardware improvements, enabling more powerful processors and lower cost per transistor as density increases. The other options are laws from physics or chemistry that describe unrelated phenomena, so they don't apply to how quickly semiconductor devices scale. While Moore's Law has guided expectations for decades, it's a trend rather than a physical law, and progress has slowed as transistors approach atomic scales, prompting research into new architectures and materials to keep performance gains going.
