Understanding CPU Architecture

What is a CPU core?

• A CPU core is a processing unit within a CPU that can execute instructions independently.

• A CPU core is a software application that manages hardware.

• A CPU core is a cooling component for the CPU.

• A CPU core is a type of memory storage.

What is a dual-core processor?

• A dual-core processor has four cores for processing.

• A dual-core processor is a CPU with two cores that can execute multiple instructions simultaneously.

• A dual-core processor is a single-core CPU that runs faster.

• A dual-core processor is a type of graphics card.

How many cycles per second does a CPU with a clock speed of 3.2 GHz execute?

• 3.2 billion cycles per second

• 32 billion cycles per second

• 320 thousand cycles per second

• 3.2 million cycles per second

How many machine cycles does the fetch part of the instruction cycle require?

• 4

• 2

• 1

• 3

What is the relationship between clock speed and machine performance?

• Lower clock speed is preferable for optimal performance.

• Higher clock speed always guarantees better performance.

• Clock speed has no impact on machine performance.

• Higher clock speed typically improves machine performance, but it is not the sole factor.

What are the three levels of cache in a CPU?

• L1, L2, L3

• L1, L2, L4

• L1, L2, L3, L4

• L0, L1, L2

How does cache size affect CPU performance?

• Cache size has no impact on CPU performance whatsoever.

• Increasing cache size can cause more frequent data access delays.

• Larger cache sizes generally improve CPU performance by reducing data access times.

• Smaller cache sizes always lead to faster CPU performance.

What is a quad-core processor?

• A quad-core processor is a type of graphics card.

• A quad-core processor has eight cores for better performance.

• A quad-core processor is a type of memory storage device.

• A quad-core processor is a CPU with four cores that can execute multiple instructions simultaneously.
