Explanation:
Detailed explanation-1: -The CPU continuously performs the machine cycle in order to execute the program instructions one by one. The instruction cycle consist of sequence of four steps. These four CPU operations includes Fetch, Decode, Execute and Store.
Detailed explanation-2: -The fetch-execute cycle (also known as fetch-decode-execute cycle) is followed by a processor to process an instruction . The cycle consists of several stages. The memory address held in the program counter is copied into the MAR . The address in the program counter is then incremented-increased-by one.
