Which factor can affect processor performance of a CPU?

• A. Hard drive space
• B. Benchmark
• C. Clock speed
• D. Number of peripheral devices connected

Answer: (C)

Clock speed determines how fast the CPU can execute instructions. It sets the number of cycles the processor can perform in one second, so a higher clock speed means more instructions processed per unit of time and usually faster overall performance for many tasks. While other factors like CPU architecture, number of cores, and cache size also affect performance, the option that directly influences how quickly the processor works is its clock speed. Hard drive space doesn’t change how fast the CPU executes instructions; it can affect overall system responsiveness but not the CPU’s execution rate. A benchmark measures performance, it doesn’t by itself cause the CPU to run faster. The number of peripheral devices impacts input/output load more than the core speed of the processor.
