    Study Notes

    Introduction to System Software

    • System software is a category of programs crucial for computers.
    • These programs run the computer and peripheral devices smoothly.

    Types of System Software

    • Two main categories:
      • Operating systems (OS)
      • System utilities

    Operating System (OS)

    • An essential component of every computer system.
    • The first program loaded into memory.
    • Functions to:
      • Start the computer
      • Manage programs
      • Distribute memory
      • Coordinate processor and peripherals
      • Enable user interaction

    Operating System Functions

    • File Management: Organizing and controlling files
    • Input/Output Management: Handling data transfer between devices and computer
    • Memory Management: Allocating and managing memory for programs
    • Resource Management: Managing resources like memory, disk space, and CPU time
    • Command Interpreter: Allows users to interact with the OS
    • System Security: Protecting the system from unauthorized access

    Starting the Computer

    • The cold boot process begins when the power is on.
    • Steps in a cold boot:
      • ROM loads BIOS (Basic Input/Output System).
      • BIOS performs a POST (Power-on Self-Test).
      • BIOS searches for the OS in CMOS settings.
      • The kernel (essential OS components) loads into memory from storage.
      • OS takes control of the computer.

    Computer System Architecture

    • The operating system sits between the user and hardware.
    • Application programs run on top of the OS.
    • Examples of prominent OSs:
      • MS-DOS
      • macOS
      • UNIX
      • Linux
      • Windows 3.X
      • Windows 95
      • Windows 98
      • Windows NT
      • Windows 2000
      • Windows XP
      • Windows CE
      • Windows 7,8,10,11,12

    UNIX

    • Developed by AT&T in the 1970s.
    • Features the first preemptive multitasking system.
    • Created file management and path names concepts.
    • Based on the client/server networking system.

    macOS

    • First to implement a graphical user interface (GUI) in 1984.
    • Known as an easy-to-use OS for beginners.

    Windows 3.X

    • Includes Windows 3.0, 3.1, 3.11 and Windows for Workgroups 3.1.
    • Cooperative multitasking used instead of preemptive multitasking.

    Windows 95 & 98

    • Windows 95 is considered a transitional OS.
    • Windows 98 is an improved version of Windows 95.
    • Features preemptive multitasking.

    Windows CE

    • A discontinued operating system produced by Microsoft in 1996.
    • Designed for mobile and embedded devices.

    Windows NT

    • Designed for client/server systems.
    • Two key components: Windows NT workstation and server.
    • Focuses on business needs.
    • Contains security features, remote administration services and directory services.

    Windows 2000

    • Two versions: 2000 Professional and 2000 Server.
    • Offers better stability and more features than Windows NT.

    Windows XP

    • Replaced earlier Windows versions.
    • Three key versions: XP Home Edition, XP Professional and XP Server.

    Linux

    • Developed in 1991 by a UNIX creator.
    • Competes with Windows and macOS.
    • Known as strong, free and widely used.
    • Uses Apache web server.

    Windows 7/8/10/11/12

    • Latest versions of Windows operating system, with improved features and capabilities.

    System Utilities

    • Programs assisting the OS in managing resources.
    • Examples of utilities
      • File management
      • File finders
      • Backup utilities
      • Antivirus software
      • File compression
      • Disk scanning
      • File defragmentation

    Antivirus Software

    • Protects the system from viruses.
    • Best antivirus programs
      • McAfee
      • BitDefender
      • Norton
      • AVG
      • Microsoft Defender

    File Compression Utility

    • Reduces file sizes by compressing data.

    Disk Scanning Utility

    • Detects and fixes storage device issues.

    File Defragmentation Utility

    • Improves storage device performance by reorganizing files.
