  1. Question 1

    Q1. If a CPU has a clock speed of 2.5 GHz and CPI is 2, what is the execution time for 10^9 instructions?

    • A) 0.8 seconds
    • B) 1 second
    • C) 1.25 seconds
    • D) 2 seconds

    Answer: 0.8 seconds

    Explanation: Execution time = (instructions * CPI) / clock speed = (10^9 * 2) / (2.5 * 10^9) = 0.8 seconds.
