What is the purpose of measuring cache impact? a) measuring impact on time b) measuring impact on space c) measuring impact on I/O d) measuring impact on RAM
Understand the Problem
The question is asking about the purpose of measuring the impact of cache, specifically what aspects are affected by cache mechanisms. The options provided suggest various performance metrics that could be impacted by cache use, leading to an evaluation of time, space, I/O operations, or RAM utilization.
Answer
Measuring impact on time.
The purpose of measuring cache impact is measuring impact on time.
Answer for screen readers
The purpose of measuring cache impact is measuring impact on time.
More Information
Cache memory is primarily used to speed up the data access time for the CPU by storing frequently accessed data, thereby improving overall processing time. It acts as a bridge between the CPU and slower main memory.
Tips
A common mistake is to assume cache impacts space or RAM primarily, rather than focusing on the speed (time) improvement aspect.
