    Study Notes

    Information Systems Concepts

    • Information: Processed and interpreted data that creates value by organizing relationships.
    • System: A group of components working together with inputs, processing, and outputs.
      • Closed System: Does not interact with other systems.
      • Open System: Interacts with other systems.
    • Information Systems (IS): Combine people, hardware, software, communication networks, data resources, and policies to store, retrieve, transform, and distribute information within an organization.

    Framework of Major Areas

    • Focuses on:
      • Foundation Concepts: Fundamental behaviors, technical business, and managerial concepts of IS.
      • Information Technologies: Major concepts, developments, and management problems in IT.
      • Business Applications: Major uses of IS for operations, management, and gaining competitive advantage.
      • Development Process: Planning, developing, and implementing IS to meet business opportunities.
