Detailed explanation-1: -The CPU interacts closely with primary storage, or main memory, referring to it for both instructions and data.
Detailed explanation-2: -The correct answer is cache memory. Cache memory is a memory that temporarily stores frequently used instructions and data for quicker processing by the central processing unit (CPU) of a computer. It is used to store program data that is currently being executed in the CPU.
Detailed explanation-3: -An instruction, stored in the memory, is fetched into the control unit by supplying the memory with the address of the instruction. The control unit decodes the instruction in order to find the sequence of operation necessary to execute it.
Detailed explanation-4: -Main memory holds instructions and data when a program is executing, while auxiliary memory holds data and programs not currently in use and provides long-term storage.
Detailed explanation-5: -data and instructions are both stored together in the same RAM. instructions are fetched from memory one at a time and in order-serially. the processor decodes and executes an instruction, before cycling around to fetch the next instruction. the cycle continues until no more instructions are available.
