Which of the following is a characteristic of cache memory in a memory hierarchy?Question 8Answera.Larger capacity than main memoryb.Slower access time than main memoryc.Smaller capacity than main memoryd.Used for long-term storage
Solution
The characteristic of cache memory in a memory hierarchy is c. Smaller capacity than main memory.
Here's why:
a. Cache memory does not have a larger capacity than main memory. It's actually smaller because it's designed to temporarily store copies of data from the most frequently used main memory locations.
b. Cache memory does not have a slower access time than main memory. In fact, it's faster. That's why it's used - to speed up data access by having it readily available in the cache, which is quicker to access than main memory.
d. Cache memory is not used for long-term storage. It's used for temporary storage of data that's frequently accessed to speed up processing times. Long-term storage is typically handled by devices like hard drives or SSDs.
