Content Outline

  1. Definition of Software
    • Software refers to a set of instructions or programs that tell a computer how to perform specific tasks. Unlike hardware, which is the physical part of a computer, software is intangible and enables the computer to function properly.
    • Software can be broadly categorized into system software and application software.
  2. Types of Software
    • System Software: This is the software that manages and controls computer hardware and enables the application software to run. It acts as a bridge between the hardware and user applications.
      • Examples of System Software:
        • Operating System (OS): Manages computer resources and provides a user interface (e.g., Windows, macOS, Linux).
        • Utility Software: Performs maintenance tasks (e.g., antivirus software, disk management tools).
      • For more on system software, refer to TechTerms – System Software.
    • Application Software: These are programs designed to perform specific tasks for the user. Application software makes use of the capabilities of the system software to perform functions like word processing, graphic design, and web browsing.
      • Examples of Application Software:
        • Word Processing Software: Microsoft Word, Google Docs.
        • Spreadsheet Software: Microsoft Excel, Google Sheets.
        • Graphics Software: Adobe Photoshop, CorelDRAW.

  3. Differences Between System and Application Software
    • System Software:
      • Manages hardware resources.
      • Helps run other software.
      • Examples: Operating systems (Windows, Linux), Device drivers, Utilities.
    • Application Software:
      • Performs specific tasks for users.
      • Works with system software to perform functions like creating documents, playing games, and browsing the internet.
      • Examples: Microsoft Word, Excel, Adobe Photoshop.
  4. Comparison of System and Application Software
    • System Software is essential for the basic operation of a computer system, while Application Software enables users to perform specific tasks.
    • System Software typically runs in the background and is not visible to users, while Application Software is directly interacted with by users to complete tasks.
