How often does Moore's Law predict that computer processing power will double?

Moore's Law, formulated by Gordon Moore in 1965, predicts that the number of transistors on a microchip will double approximately every 18 months, leading to a corresponding increase in computing power. This phenomenon reflects the exponential growth of technology, where advancements are not merely linear but accelerate over time due to improvements in manufacturing processes and design. The original observation highlighted a trend within the semiconductor industry that has held for several decades and has significantly influenced the rate of innovation and development in computing technology.

The choice indicating 18 months aligns perfectly with the traditionally accepted interpretation of Moore's Law in the context of the rapid advancements in computer processing capabilities, making it the correct response to the question.
