To determine the time it takes for the number of transistors on a microchip to double according to Moore's Law, we'll analyze each provided option.
1. Moore's Law states that the number of transistors on a microchip doubles approximately every fixed period of time. This period has been observed and documented by Gordon Moore, the co-founder of Intel.
2. Among the given options:
- Option A: 2 years
- Option B: 50 years
- Option C: 10 years
- Option D: 5 years
3. Moore's Law specifies that this period is quite short, not several decades or even a decade.
4. Through historical data and the well-accepted interpretation of Moore's Law in the technology industry, we know that the number of transistors on a microchip typically doubles every 2 years.
Therefore, the correct answer is:
A. 2 years
