Which statement accurately reflects Moore's law in terms of chip progress?

• A. The number of transistors on a chip roughly doubles every two years
• B. Memory speeds quadruple every year
• C. Network bandwidth doubles every six months
• D. Power efficiency remains constant

Answer: (A)

Moore's law tracks how the density of transistors on a chip increases over time. The essence is that the number of transistors on a typical integrated circuit tends to double roughly every two years. This rapid growth in transistor count has driven bigger, more capable, and often more cost-efficient chips, even as physical sizes shrink. That makes the statement about transistor count doubling every two years the best reflection of Moore's law, because it directly describes the metric Moore observed: transistor density on a chip, not memory speeds, network bandwidth, or a claim about power efficiency. The other ideas don’t fit Moore’s law. Memory speeds quadrupling every year describe a much faster, different trajectory than Moore’s prediction and aren’t the benchmark Moore proposed. Network bandwidth doubling every six months focuses on data transfer rather than on transistor density. And power efficiency remaining constant contradicts the trend of substantial gains in efficiency that typically accompany newer, more densely packed transistors.
