Correct option is B
The correct answer is: (b) Clock speed
Explanation:
Clock speed refers to the frequency at which a CPU operates, measured in Hertz (Hz), typically in Gigahertz (GHz) for modern processors.
It determines how many instruction cycles the CPU can perform per second.
For example, a CPU with a clock speed of 3.0 GHz can theoretically execute 3 billion cycles per second, directly influencing how fast instructions are processed.
Higher clock speed generally means faster performance, but other factors like core count, architecture, and cache also play roles.
1 GHz = 1 billion cycles per second.
Most modern CPUs have multiple cores, each with their own clock speeds.
Clock speed is set by an internal oscillator synchronized to a system clock.
Modern CPUs use dynamic frequency scaling to balance power and performance.
Clock speed can be overclocked for performance or underclocked for efficiency.
