9. Basic Components of the Von Neumann Machine
9.1. THE PRINCIPLES : Data & instructions are both stored in main memory while being processed
9.2. A central processing unit (CPU); it contains the control unit (CU), arithmetic/logic unit (ALU) and Interface unit
9.3. MEMORY ; memory is short-term storage INPUT DEVICES : Mouse and scanner OUTPUT DEVICES ; Monitor and printer
9.4. STORAGE : Hard drive and optical media
10. ALU: arithmetic/logic : unitPerforms arithmetic and Boolean logical calculations
10.1. CU: control unit : Controls processing of instructions Controls movement of data within the CPU
10.1.1. Interface unit : Moves instructions and data between the CPU and other hardware components
