Resource summary

Fetch-decode-excecute
  1. The data AND the instructions are stored in the RAM
    1. The CPU sends a signal along the address bus requesting the next instruction
      1. The data inside the requested address is then sent to the CPU to be processed
        1. This data is then either executed by the CPU if its an instruction or processed if its data
          1. The control unit decodes the data
            1. If needed the ALU acts upon the information
              1. Finally this is sent to an output device or secondary storage.
