Questions and Answers

What is the main purpose of cache memory?

To store program and data files
To provide a fast, small memory that holds copies of frequently accessed main memory locations (correct)
To exploit the principle of locality with a small, fast memory
To interact with other memory management hardware

What is the relationship between cache memory and main memory?

Cache memory is invisible to the operating system
Cache memory is used to store program and data files
Cache memory is a copy of a portion of main memory (correct)
Cache memory is used to store secondary memory

How does cache memory exploit the principle of locality?

By accessing memory at least once per instruction cycle
By being invisible to the operating system
By interacting with other memory management hardware
By storing a copy of a portion of main memory that is likely to be accessed in the near future (correct)
