    Study Notes

    Computer Organization

    • Refers to the structure and interconnection of various units within a computer system
    • The physical arrangement and communication pathways between these units
    • Deals with the implementation of computer architecture, focusing on the hardware elements and how they function together

    Functional Units of a Computer

    • Input Unit: Receives raw data and converts it into a form the computer can understand
    • Output Unit: Presents processed data from the computer in a human-readable format
    • Memory Unit: Stores data and instructions for the CPU to access
    • Arithmetic Logic Unit (ALU): Performs arithmetic and logical operations on data
    • Control Unit: Directs and coordinates the operations of all other units in the computer

    Computer Architecture

    • Concerns the operational units of a computer and their interconnections
    • Defines the functional behavior of the system
    • Specifies how the units communicate and how information flows

    Data Flow

    • The information received by the input unit is stored in the computer's memory for later reference or immediately used by the arithmetic logic unit (ALU) circuitry.

    Control Unit

    • The brains of the computer, responsible for the sequence of operations
    • Interprets instructions from the memory unit
    • Issues control signals to other units to execute the instructions
    • Coordinates the activities of all other units.

    Non-Functional Unit

    • Hard Drive (Secondary Storage): While essential for storing and retrieving data, it's not considered a functional unit within the traditional computer architecture model.
    • Hard drives are storage devices that act as an extension of memory and are not directly involved in the operational flow of the central processing unit (CPU).
