question 20 of 25
what does the number of hertz measure in a cpu?

a. how quickly the data in ram can be read, changed, and
overwritten
b. how much data is stored magnetically and is used for long - term
storage
c. how fast a cpu can process data, indicating performance
d. how many bits are fed into a cpu in a certain amount of time

Explanation:

• Option A: RAM speed is measured by other metrics (like MHz for DDR RAM), not CPU hertz. So A is incorrect.
• Option B: Long - term storage (like hard drives) capacity and speed are measured differently, not by CPU hertz. So B is incorrect.
• Option C: The number of hertz (clock speed) of a CPU measures how many cycles the CPU can complete per second, which relates to how fast it can process data and is an indicator of its performance.
• Option D: The number of bits fed into a CPU in a certain amount of time is related to the bus width and bandwidth, not the CPU's clock speed (hertz).

Answer:

C. How fast a CPU can process data, indicating performance
