What is the process by which the CPU accesses data from main memory?

• Memory fetch

• Memory read

• Memory access

• Memory transfer

What is the term used to describe the speed at which the CPU can access data from main memory?

• Memory bandwidth

• Memory latency

• Memory clock speed

• Memory access time

What is the role of the memory controller in reading/writing data between the CPU and main memory?

• To coordinate data transfer between CPU and memory

• To manage memory access requests

• To regulate the memory clock speed

• To perform error correction on memory data

What is caching and how does it improve the speed of data access for the CPU?

• Caching is the process of storing frequently accessed data in a small, fast memory area to reduce access time

• Caching is the process of compressing data in memory to save space

• Caching is the process of encrypting data stored in memory for security

• Caching is the process of copying data from main memory to disk to free up memory

How does the size of the cache affect the performance of the processor?

• Larger cache size can improve performance by storing more data for faster access

• Smaller cache size can improve performance by reducing cache access time

• The size of the cache does not have a significant impact on performance

• Performance is not related to the size of the cache

What is the impact of memory latency on processor performance?

• High latency can decrease processor performance

• Low latency can increase processor performance

• Latency has no impact on processor performance

• Latency can both increase and decrease processor performance depending on other factors

How can memory bandwidth be improved to enhance processor performance?

• By increasing the clock speed of memory

• By increasing the size of the memory modules

• By increasing the number of memory modules in the system

• By optimizing memory access patterns in the software

What is the relationship between clock speed and processor performance?

• High clock speed generally leads to better performance

• Low clock speed generally leads to better performance

• The clock speed has no direct relationship with processor performance

• Processor performance depends on both clock speed and other factors such as architecture and memory bandwidth

How does the number of cores in a processor affect its performance?

• More cores generally lead to better performance for parallel tasks

• Fewer cores generally lead to better performance for serial tasks

• The number of cores has no direct impact on performance

• Processor performance depends on both the number of cores and other factors such as clock speed and memory bandwidth

What is hyper-threading and how does it improve processor performance?

• Hyper-threading is a technology that allows a single physical core to appear as multiple logical cores to the operating system, potentially improving performance

• Hyper-threading is a technology that speeds up memory access for the processor

• Hyper-threading is a technology that increases the clock speed of the processor

• Hyper-threading is a technology that reduces power consumption of the processor
