question 21 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 not measured by CPU hertz. CPU hertz relates to CPU processing, not RAM operations.
• Option B: Long - term magnetic storage (like hard drives) capacity or speed is not measured by CPU hertz. Hertz for CPU is about processing speed, not storage.
• Option C: CPU clock speed (in hertz) measures the number of cycles per second the CPU can perform, which indicates how fast it can process data and is a key performance indicator.
• Option D: The number of bits fed into a CPU in a certain time is related to bus width or data transfer rate, not CPU clock speed (hertz).

Answer:

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