Cycle

I learned that the cycle in the CPU come from the Input Device where it will transfers the instructions and data to the Main Memory or the RAM. Then, the memory will transfer it the CPU where it will be process and the CPU will transfer the data back to the Main Memory while the instructions will be store in CPU. The memory will process it and transfer the result to the Output Device.

(P.S. I will not explain the second cycle or picture in the moodle because I can't understand it.)
