    Study Notes

    CPU Components

    • The three major components of a CPU are the Arithmetic Logic Unit (ALU), Control Unit (CU), and Memory Unit.
    • The ALU carries out mathematical tasks and logic operations essential for processing instructions.

    Control Unit Functions

    • The Control Unit (CU) is responsible for fetching instructions from memory, interpreting them, and directing the operation of the ALU and other components.

    Interaction between Memory Unit and ALU

    • The Memory Unit interacts with the ALU by supplying the necessary data and instructions for processing operations.

    CPU Execution Cycle

    • The stage that follows instruction decoding in the CPU execution cycle is the execution phase, where instructions are carried out.

    Interpretation of Software Instructions

    • The Control Unit (CU) interprets software instructions and coordinates the actions of the CPU components.

    Decision-making in CPU

    • The Control Unit is also responsible for making decisions and selecting the proper path in a program's execution based on the instructions provided.

    Primary Function of the ALU

    • The primary function of the ALU is to perform arithmetic calculations and logical operations on data.

    Temporary Storage in CPU

    • Registers are the part of the CPU that temporarily stores data and instructions actively being processed.

    Fetching Instructions

    • The Control Unit is mainly involved in fetching instructions from memory when dealing with program logic.

    Role of Registers

    • Registers serve as high-speed storage locations for data that the CPU needs immediately during processing.

    Computer Component Interconnectivity

    • The bus subsystem connects all CPU components, functioning like a system of roads to facilitate communication.

    Instruction Execution

    • The ALU is the component of the CPU that executes instructions received from memory.

    Temporary Data and Instruction Storage

    • The Memory Unit temporarily stores data and instructions during processing for quick access by the CPU.

    Hardware Components

    • The CPU, motherboard, and power supply are among the essential hardware components in a computer system.

    Function of the Bus

    • The primary function of the bus is to transfer data and instructions between different components of the computer system.

    Long-term Data Storage

    • Components such as hard drives, disks, and CDs are responsible for long-term storage of data within a computer system.
