- - - - Performs all basic arithmetic, logical or input/output operations
    - - Holds data that is to be used by the ALU and then saved to RAM. MDR is similar to MAR. Whichever memory location the MAR is holding, the corresponding data will be sent to MDR for processing by the ALU
    - - Responsible for the operation of the CPU
      - Controls instructions given from the primary memory
      - Provides ALU with data that needs to be processed
      - Contains various registers. Register is a small storage location that holds data. In multiples of 8bits. Size of a register in bytes is a WORD. 64bit register holds 64 bits, thus 8 * 8 = 64bits. A 64bit computer has a word size of 8 bytes
    - - Holds memory address of data that is going to be used by ALU. May also hold data that has been processed. In order for the MAR to communicate with the primary memory a memory bus is needed

      - ALU
- - - - Processing phase: Other data that is needed to be inputted can also come from the storage of the computer system. Any new information gained in this process can also be saved in the storage system
      - Example: Camera's follow an input, process, output and storage model. Input is pressing the button to take a picture
        
        The process that the camera's computer system takes is to capture the light through the lens and convert it to a digital image
        
        Output is the digital image that can be viewed on a monitor
    - - Process
        
        Output (Information)
