    Study Notes

    Computer Hardware Review

    • Computer hardware refers to the tangible components of a computer, including CPU, RAM, monitor, and input devices.
    • Hardware is categorized into four categories: Input Devices, Output Devices, Storage Devices, and Internal Components.

    Hardware Components

    • Input Devices allow user interaction with the computer, including keyboard, mouse, scanner, light pen, and barcode reader.
    • Output Devices communicate results to the user in a readable format, such as monitors, printers, and speakers.
    • Internal Components are essential for a computer’s operations and include components like the motherboard and RAM.

    Operating System Definition

    • An Operating System (OS) is a vital system software that manages hardware resources and provides essential services for application programs.
    • It acts as an intermediary between hardware and software, ensuring efficient use of CPU, memory, and storage.

    Operating System Views

    • User View: Focuses on user interaction with the OS through applications; encompasses single-user, multiple-user, and embedded user viewpoints.
    • System View: Centers on how the system manages hardware and software resources to maximize performance and resource allocation.

    User Viewpoint

    • Single User Viewpoint: Designed for individual user needs without a focus on performance efficiency.
    • Multiple User Viewpoint: Supports several users connected to a mainframe, requiring effective memory allocation.
    • Handled User Viewpoint: Utilizes touch-screen technology for interaction, common in smartphones and embedded systems, limiting direct user engagement.

    System Viewpoint

    • The operating system manages various hardware resources, including registers, RAM, and CPUs.
    • It strategically allocates resources using techniques like paging, virtual memory, and caching.
    • Controls how input/output devices communicate with the operating system based on user requests.

    Learning Outcomes

    • Understanding functions of major computer hardware components.
    • Defining operating systems, identifying their types and functions.

    Multiple Choice Questions (MCQs)

    • MCQs test understanding of categorization and functions of hardware and operating systems in various contexts.

    Summary

    • Computer systems consist of carefully selected hardware and corresponding software to operate effectively.
    • The operating system is crucial for resource management, user interaction, and overall system functionality, recognized in both user and system perspectives.
