Explanation:
Detailed explanation-1: -The CPU fetches the instructions one at a time from the main memory into the registers. One register is the program counter (pc). The pc holds the memory address of the next instruction to be fetched from main memory. The CPU decodes the instruction.
Detailed explanation-2: -To actually run the code, the processor then needs to retrieve instructions one by one from memory so it can run them. This process consists of three stages: fetching the instruction, decoding the instruction, and executing the instruction-these three steps are known as the machine cycle.
