     * CPU: Contains the control unit, arithmetic logic unit and main memory
       * CU: Control unit handles all processor control signals. It directs I/O flow, fetches code for instructions and controls how data moves around.
       * ALU: The arithmetic logic unit is that part of the CPU that handles all the calculations the CPU may need. It performs logical, bit shifting and arithmetic operations.
-      * MU: Main memory unit contains the accumulator, program counter, memory address register, memory data register, current instruction register and instruction buffer register.
-    * Output device: Includes display, speakers etc.
