    Study Notes

    Computer Software

    • Computer software are electronic instructions and procedures that command and control computer operations.
    • Software tells the computer what to do.

    Types of Software

    • System software: Enables the computer to work and control connected devices.
    • Application software: Performs specific user tasks.

    System Software

    • A set of programs designed to manage computer operations and provide access to computer resources.

    • Functions include:

      • Booting the computer
      • Ensuring hardware functions correctly
      • Managing application program operations (retrieving, loading, executing)
      • Managing files (storing and retrieving)
      • General system utility functions

    Categories of System Software

    • Operating System: Manages daily computer operations and resources.
      • Types:
        • Stand-alone operating system
        • Network operating system
        • Embedded operating system
      • Examples: Windows, Linux, Unix, MacOS, Chrome OS, Android.
    • Utility programs: Configures, analyzes, optimizes, and maintains computer operations.
      • Functions: Virus detection/removal, screen optimization, disk error checking, file management (merging, sorting, encryption, defragmentation), data compression. Examples: Antivirus, disk checkers, backup utilities, disk compressors, disk defragmenters.
    • Programming languages (translators): Tools used to translate source code to machine code.
      • Types: Assemblers, compilers, interpreters

    Operating System (OS) Functions

    • Processor management (multitasking, time sharing)
    • Peripheral device control
    • Application software installation support
    • Booting process control
    • System performance monitoring
    • Security administration
    • File management
    • Device configuration
    • Task scheduling
    • Network connection establishment

    Operating System User Interfaces

    • Command-line interface: User types commands to interact with the computer.
      • Advantages: Fast execution, low memory consumption, ideal for programming.
      • Disadvantages: Commands need to be memorized and typed correctly, limited graphics. Examples: DOS, Unix, Linux
    • Graphical user interface (GUI): User interacts with the computer using icons, menus, and visuals.
      • Advantages: User-friendly, no need to memorize commands, similar interface across applications, mouse navigation supported.
      • Disadvantages: Requires more memory and processing power, difficult for complex automation, more susceptible to viruses, not ideal for programming.

    Utility Software

    • Designed for computer configuration, analysis, optimization, and maintenance.
    • Examples include: Antivirus, disk checking software, backup utilities, data compression utilities, disk compressors, disk defragmentation software.

    Programming Languages

    • Used to write computer instructions/programs.
    • Types:
      • Low-level languages: Machine code, Assembly language.
        • Close to machine language.
        • Uses numbers (binary code) to execute an instruction.
        • Difficult to understand and manage
        • Runs faster.
        • Example: Machine code language.
      • High-level languages: COBOL, Pascal, Python, Java, C.
        • Languages that are closer to human language than machine language.
        • Easy to understand, write, debug, correct and modify
        • Needs to be translated to machine language (use compilers or Interpreters) to execute.
    • Language Processors/Translators: Translate high-level languages to machine code.
      • Examples: Compilers, Interpreters, Assemblers, Linkers, Language Editors

    Application Software

    • Programs that perform specific tasks for users.

    • Types:

      • Off-the-shelf software. -Customized programming/bespoke software. -Examples: Word processors, spreadsheet software, presentation software, database software, desktop publishing software, imaging software. Web browsing, web authoring, media players, accounting, audio/video editing.

    • Benefits of using a software suite: cost-effectiveness, similar user interface, easy installation.

      • Examples: Microsoft Office Suite, Open Office.

    Common Terms in Software

    • Software License: Document outlining the use and distribution guidelines for software.
    • Software Agreement: Legal contract between software licensor and buyer.
    • Software Piracy: Illegal duplication of copyrighted software.
    • Software Bug: Error in software code preventing proper functioning.
    • Beta Software: Software released for testing purposes before official release.
    • Software Release: Process of making software available to users.
    • Software Version: A variation of existing software with modifications.
    • Hot Fix: Software to fix a bug or security hole in an existing program.
    • Spyware: Malicious software to gather information.
    • Software Patch: Changes made to correct errors in software.
    • Software Upgrade: Replacing a software version with a newer one.
