• Cache memory is a sort of volatile computer memory that stores frequently used computer programmes, applications, and data and offers high-speed data access to a CPU.
• Cache is a type of temporary memory storage that enables data retrieval easier and more efficient. It is the computer's quickest memory, and it is usually built into the motherboard and directly into the CPU or primary random access memory (RAM).
• Cache memory speeds up data storage and access by storing instances of programmes and data that the CPU accesses frequently. As a result, when a processor requests data that already exists in the cache memory, it does not have to access the main memory or the hard disc.
• The quickest memory available is cache memory, which functions as a buffer between RAM and the CPU. Every time the processor wants to read or write a location, it checks whether a corresponding entry is accessible in the cache, minimising the time it takes to access data from the main memory.
