Final answer:
Instructions and data most often used by the CPU are stored in Cache memory. It is a type of volatile memory that allows for quick retrieval of information, enhancing CPU efficiency by reducing the need to access slower main memory or storage devices.
Step-by-step explanation:
The computer stores instructions and data that are used most often by the CPU in Cache memory. The cache is a smaller, faster type of volatile memory located directly on the CPU or very close to it on the motherboard. It serves as a temporary storage area where the CPU can retrieve data and instructions quickly without having to access the slower main memory (RAM). There are typically multiple levels of cache, with Level 1 (L1) being the fastest and smallest, and higher levels being progressively larger but slower. Accessing data from cache is significantly faster than accessing data from the RAM or other storage devices like the hard drive or the SSD.
The computer stores instructions and data that are used most often by the CPU in Cache memory. Cache memory is a small, high-speed memory located between the CPU and main memory. It stores frequently accessed instructions and data to minimize the time taken for the CPU to access them. As a result, the CPU can retrieve the data and instructions from the cache memory much faster than if it had to fetch them from the main memory or other storage devices.
