The speed of a processor is commonly measured in
Answer: D
Correct answer: Gigahertz
Processor speed is quoted in gigahertz, the number of clock cycles per second - 3 GHz meaning three billion cycles a second. It is a poor measure of performance on its own, and knowing why matters more than knowing the unit. Two processors at the same clock speed can differ greatly because of the number of cores, the instructions completed per cycle, the size of the cache, and the memory bandwidth available. Comparing clock speeds across different architectures is close to meaningless. The distractors measure other things entirely: gigabytes measure storage or memory capacity, megabits per second measure network speed, and dots per inch measure printer or scanner resolution. Modern processors also vary their clock dynamically, running below the nominal speed when idle to save power and boosting above it briefly under load - so the quoted figure is a base rating rather than a constant.
