What is the significance of measuring CPU speed in gigahertz (GHz)?

• A. It indicates the physical size of the CPU
• B. It represents billions of cycles per second
• C. It shows the number of cores in the CPU
• D. It correlates directly with power consumption

Answer: (B)

Measuring CPU speed in gigahertz (GHz) signifies that the CPU can perform billions of cycles per second. This unit of measurement reflects the frequency at which a processor operates and is crucial in determining the processing power and efficiency of the CPU. A higher gigahertz rating typically means the CPU can execute more instructions per second, leading to improved performance in applications, particularly those that are CPU-intensive. Understanding this metric helps technicians and users gauge the speed and responsiveness of a computer system, making it a key component in evaluating hardware capabilities.
