    Study Notes

    Computer Model and Structure

    • Computers operate on the Input-Process-Output (IPO) model, where data is input, processed, and outputted.
    • Examples include adding numbers (e.g., 101 + 300 = 401) and printing documents (e.g., Test.docx printed as papers).

    Components of a Computer System

    • Three main components are hardware, software, and peopleware.
    • Hardware includes input devices like keyboards and mice, output devices such as monitors and printers, and storage options like HDD and SSD.
    • Software is categorized into system software, utility software, and application software.

    Central Processing Unit (CPU)

    • The CPU consists of the Control Unit (CU), Register, Cache, and Arithmetic Logic Unit (ALU).
    • The CPU processes input data through the steps of decoding, executing, and producing output data.
    • Main memory (RAM) temporarily stores data for quick access while executing programs.

    Memory Hierarchy

    • Cache Memory: Fastest but smallest memory, typically volatile (e.g., Static RAM).
    • Main Memory: Larger, slower, often Dynamic RAM; available as DIMM and SO-DIMM.
    • Secondary Storage: Non-volatile devices (HDD, SSD, flash drives) for permanent data storage, characterized by larger capacity but slower speeds.

    Motherboard and Expansion

    • The motherboard integrates various components and determines compatibility of hardware installations.
    • Key features include CPU socket, RAM slots, and connections like SATA and expansion cards.

    Expansion Cards

    • Expansion cards enhance computer capabilities; types include Graphics Processing Units (GPUs) for better graphics handling and Network Interface Cards (NICs) for Internet connectivity.

    Output Interfaces

    • Different outputs are managed through connectors like VGA, DVI, HDMI, and Display Port, each having varying resolutions and capabilities.

    Software Types

    • Software is categorized into:
      • System Software: Controls hardware operations and user interactions (e.g., operating systems like Windows, Linux).
      • Utility Software: Provides system efficiency (e.g., antivirus programs, disk management).
      • Application Software: Serves specific tasks (e.g., word processors, web browsers).

    Operating Systems

    • Different OS types serve various functions, including:
      • Real-Time OS for time-sensitive tasks,
      • Single User/Multitask OS for running multiple applications,
      • Multi-User OS for concurrent use in environments like servers.

    Utility Software

    • Designed for system efficiency, encompassing security software (e.g., antivirus), disk management tools, and backup utilities.

    Programming Languages

    • Software is created using programming languages, which can be procedural, functional, or logical.
    • Licensing includes proprietary software, free software, and open-source software (FOSS) like Linux.

    Peopleware

    • Refers to the users manipulating computers and software for personal and professional needs, covering activities from office productivity to programming.
