What major prediction describes the doubling of transistor count in integrated circuits approximately every 18 to 24 months?

Moore's Law refers to the observation made by Gordon Moore, co-founder of Intel, stating that the number of transistors on an integrated circuit would double approximately every two years, leading to an exponential increase in computing power over time. This phenomenon has significant implications for technology advancement and economic growth, as it suggests that as circuitry becomes more densely packed, the performance of computers and other electronic devices can improve dramatically while the cost per transistor decreases.

The other laws mentioned do not pertain to transistor counts. Metcalfe's Law relates to the value of a network being proportional to the square of the number of connected users, emphasizing the importance of network growth. Zipf's Law relates to word frequency distributions and does not apply to hardware technology. Gordon's Law does not have a recognized definition within the context of computing or electronics. Therefore, the prediction associated with the doubling of transistor count in integrated circuits aligns directly with Moore's Law.
