In modern CPUs __________ is used for storing frequently accessed data for faster processing.
Answer: D
The answer is Cache.
Cache memory is a small, very fast memory built into or beside the CPU. It keeps copies of the data and instructions the processor uses most often, so they can be fetched far faster than from main memory.
RAM is the main working memory and is slower than cache. A hard drive is secondary storage, much slower again. ROM holds fixed start-up instructions such as firmware and is not used to speed up access to frequently used data.
