Answer:
1.48 s
Explanation:
Number of instructions = 500 million = 500 * 10⁶
clock rate = 1 / 2.2 GHz = 1 / (2.2 * 10⁹ Hz) = 0.4545 * 10⁻⁹ s
We need to compute the clocks per instruction (CPI)
The CPI = summation of (value * frequency)
CPI = (50% * 3 clock cycles) + (50% * 10 clock cycles)
CPI = (0.5 * 3) + (0.5 * 10) = 1.5 + 5 = 6.5
Execution time = number of instructions * CPI * clock rate
Execution time = 500 * 10⁶ * 6.5 * 0.4545 * 10⁻⁹ =1.48 s

These companies develop their own software that enables them to build and maintain searchable databases of web pages (the engine), and to organise those pages into the most valuable and pertinent way to the user.</span>
