Detailed explanation-1: -The purpose of cache memory is to store program instructions and data that are used repeatedly in the operation of programs or information that the CPU is likely to need next. The computer processor can access this information quickly from the cache rather than having to get it from computer’s main memory.
Detailed explanation-2: -For desktop and laptop computers, Windows is the most used at 76%, followed by Apple’s macOS at 16%, and Linux-based operating systems at 5% (i.e. “desktop Linux” at 2.6%, plus Google’s ChromeOS at 2.4%, in the US up to 6.2%).
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: -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.
