What I Learned in CompSci #34: Processing Cycle

Processing Cycle
     -how the computer work cycle

Explain this Picture

1. Through the input device, we send instructions and data to the Main Memory
2. The instructions and data are stored in the RAM until they are transferred to the CPU
3. The CPU converts the instructions and data to data
4. The data will then be stored in the Main Memory again
5. The data will then be shown through the output device

Explain this diagram

1. The input device sends information to the Main Memory
2. The information are then sent to the Control Unit
3. The Control Unit will then send the information to the ALU or Arithmetic Logic Unit
4. The ALU will convert the information to data and will send the data back to the Main Memory
5. From the Main Memory, you can save the data to the Secondary Memory so that you can open the data again, or you can transfer it to the Output Device
