• What is the purpose of pipelining in CPU design?

  Divide instruction execution
• What does pipelining achieve in CPU performance?

  Faster instruction throughput
• More CPU cores always result in better performance for all tasks

  False
• What does a larger cache size reduce in a CPU?

  Latency
• A higher clock speed always guarantees better CPU performance

  False
• A larger cache size improves data retrieval
• A larger cache size reduces latency and improves data retrieval speed.
• Cache memory is located close to the CPU to store frequently accessed data and instructions.


  True
• Parallel processing uses multiple cores to execute different instructions simultaneously.


  True
• What is the impact of higher clock speed on CPU performance?

  Faster instruction execution
• More cores enhance multitasking and complex tasks.
• A CPU with a 3 GHz clock speed completes 3 billion cycles per second.

  True
• A larger cache can store more frequently used data, improving system responsiveness.


  True
• Match the CPU metric with its impact on performance:

  Clock Speed ↔️ Faster instruction execution
