Detailed explanation-1: -cache memory, also called cache, supplementary memory system that temporarily stores frequently used instructions and data for quicker processing by the central processing unit (CPU) of a computer. The cache augments, and is an extension of, a computer’s main memory.
Detailed explanation-2: -The data in a cache is generally stored in fast access hardware such as RAM (Random-access memory) and may also be used in correlation with a software component. A cache’s primary purpose is to increase data retrieval performance by reducing the need to access the underlying slower storage layer.
Detailed explanation-3: -At the highest level, the most frequently used information-say, the instructions in a loop which execute repeatedly-is stored directly on a special section of the processor chip, called Level 1 (L1) cache. This is the fastest memory of all.
Detailed explanation-4: -CPU cache: This is a small amount of memory built into a computer’s central processing unit (CPU) that stores frequently accessed data and instructions. The CPU cache makes it faster for the CPU to get to data and instructions, so it doesn’t have to go to the slower main memory or storage devices as often.
Detailed explanation-5: -Cache memory is a chip-based computer component that makes retrieving data from the computer’s memory more efficient. It acts as a temporary storage area that the computer’s processor can retrieve data from easily.
