Moore's Law says the number of integrated circuit chips in a computer doubles every two years, implying computers become twice as powerful every two years. According to Moore's Law, how many years from now will computers be 32 times more powerful than they are now?
A5 years
B10 years ✓ Correct
C12 years
D8 years
Correct answer: (B) 10 years — Computers will be 32 times more powerful in 10 years, so option B is correct.
Explanation
★Computers will be 32 times more powerful in 10 years, so option B is correct.
★Moore's Law says power doubles every two years.
★A factor of 32 equals 2 to the power 5, so five doublings are needed.
★Each doubling takes two years, so five doublings take ten years.
★Hence in ten years the power grows by a factor of 32.
★Exponential growth is captured by counting how many doublings reach the target factor.
★Moore observed this trend in transistor counts on integrated circuits in 1965.
