Which term describes the number of cycles per second a processor can execute, typically measured in MHz or GHz?

• A. Clock speed
• B. Throughput metric
• C. Storage speed
• D. Processing speed

Answer: (D)

Clock speed describes how fast the CPU clock ticks, measured in cycles per second (Hz), commonly in MHz or GHz. Each clock cycle enables the processor to perform basic steps in instruction execution, so more cycles per second generally mean more instructions can be processed over time, all else equal. The throughput metric refers to how much work gets done per unit time and depends on workload and architecture, not just the CPU’s timing. Storage speed relates to memory or disk access, not the CPU’s clock rate. Processing speed is a broad, non-specific term that doesn’t pin down a concrete, standardized measurement like clock speed. So the term that best describes cycles per second is clock speed.
