Answers/Possible Answers
1. What does CPU stand for?
Answer: Central Processing Unit.
2. Name three factors that affect CPU performance.
Answer: Clock speed, bus width, cache memory, and number of cores.
3. Explain what clock speed is and how it impacts CPU performance.
Answer: 1 mark definition and 1 for explaining impact
Clock speed, measured in GHz, refers to how many cycles a CPU can execute per second.
Higher clock speeds generally indicate faster performance as the CPU can process instructions more
quickly.
4. How does the number of cores in a CPU affect its performance?
Answer:
CPUs with multiple cores can handle multiple tasks simultaneously, improving overall performance,
especially for multitasking or parallel processing tasks.
5. What is cache memory, and how does it influence CPU performance? (2 marks)
Answer:
Cache memory is a small, high-speed type of volatile computer memory that provides high-speed data
storage and access to the processor.
It helps improve CPU performance by reducing the time taken to access frequently used data and
instructions.
9. How does overclocking affect CPU performance, and what are the risks associated with it?
Answer:
Overclocking involves increasing the CPU's clock speed beyond its factory settings to enhance
performance.
While it can boost performance, it also generates more heat and may void the warranty. Incorrect
overclocking can lead to system instability or damage.
