   A technician is explaining the difference between two CPUs to a client. CPU A has a clock speed of 3.6 GHz. CPU B has a clock speed of 3600 MHz. The client asks which CPU will make their computer run faster. The technician needs to give the most accurate advice. Which of the following is the best response?

   • ACPU B will be faster because it has more MHz, which means it can process more instructions per second.
   • BThe comparison cannot be made because GHz and MHz are not directly comparable.
   • CBoth CPUs have the same clock speed, so other factors like cores and architecture will determine which is faster.
   • DCPU A will be faster because 3.6 GHz is a higher number than 3600 MHz.
