A CPU has a clock speed of 2.5 GHz. Calculate the number of clock cycles it completes in 4 seconds.
- Convert GHz to Hz: 2.5 GHz = 2.5 x 10^9 Hz (cycles per second).
- Multiply the number of cycles per second by the time in seconds: 2.5 x 10^9 x 4.
- Calculate: 2.5 x 4 = 10, so the result is 10 x 10^9.
- Final answer: 1 x 10^10 clock cycles (10,000,000,000).
