Which is a storage buffer that stores the data that is used more often, temporarily, and makes them available to CPU at a fast rate?

The correct answer is Cache memory.

Key Points

• Cache memory is a type of high-speed volatile computer memory that provides high-speed data access to a processor and improves the efficiency of data retrieval.
  • Cache memory is a small-sized type of volatile computer memory that provides high-speed data access to the processor and stores frequently used computer programs, applications, and data.
  • It is located close to the CPU, either on the CPU chip or on a separate chip with a dedicated connection to the CPU.
  • Cache memory is faster than the main memory (RAM) and allows for quicker data retrieval, which helps to speed up the processing time.
  • There are different levels of cache memory, such as L1, L2, and L3, with L1 being the smallest and fastest and L3 being the largest and slowest among the three.
  • Cache memory is used to reduce the time it takes to access data from the main memory by storing copies of frequently accessed data and instructions.

Additional Information

• Cache memory plays a crucial role in enhancing the performance of the CPU by minimizing the time needed to access data from the main memory.
• It operates at a higher speed than the main memory and helps in faster execution of frequently used instructions and data.
• Modern processors have multiple levels of cache memory, with each level serving different purposes and providing different levels of speed and storage capacity.
• The effectiveness of cache memory is measured by its hit rate, which is the percentage of times the requested data is found in the cache.
