COMPUTER FUNDAMENTALS

Detailed explanation-1: -Cache memory is sometimes called CPU (central processing unit) memory because it is typically integrated directly into the CPU chip or placed on a separate chip that has a separate bus interconnect with the CPU.

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: -A level 2 cache (L2 cache) is a CPU cache memory that is located outside and separate from the microprocessor chip core, although, it is found on the same processor chip package.

Detailed explanation-4: -The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations. Thus, the cache is always attached to the CPU itself and has nothing to do with the motherboard or even the memory.
