Question 27

Which of the following statements about memory hierarchies and the
principle of locality is true?
Data is stored in the memory closest to the processor and moved to lower
levels only when it is no longer needed.
Temporal locality refers to the tendency of a data item to be referenced
again soon after its initial access, while spatial locality refers to the
likelihood that items with addresses close to the accessed data will be
referenced soon.
The memory hierarchy uses the same speed and size for all levels, with only
the cost per bit varying between levels.
Memory hierarchies are designed so that data is transferred between non-
adjacent levels directly to optimize access time.
