Detailed explanation-1: -Cache memory is the fastest system memory, required to keep up with the CPU as it fetches and executes instructions. The data most frequently used by the CPU is stored in cache memory.
Detailed explanation-2: -A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.
Detailed explanation-3: -The transfer between CPU and Cache is word transfer. The word that is transmitted in the medium of the memory data bus is between the CPU and the cache is known as word transfer. It is normally of the length of a single word or a half-word.
Detailed explanation-4: -Cache memory is faster than main memory. It consumes less access time as compared to main memory. It stores the program that can be executed within a short period of time. It stores data for temporary use.
