    Data, Information, and Knowledge

    • Data refers to facts and figures that are processed, stored, and transmitted by digital systems.
    • Information is the result of organizing, analyzing, and interpreting data to reveal meaning and significance.
    • Knowledge is the result of using information to understand and make decisions.

    Systems

    • A system is a collection of components that work together to achieve a common goal.
    • An Information System is a system that collects, stores, processes, and distributes information to support decision-making.

    Information System Components

    • Hardware: physical components such as computers, servers, and networks.
    • Software: programs and applications that process and manage data.
    • Data: the facts and figures used by the system.
    • People: users, managers, and administrators who interact with the system.
    • Procedures: rules and guidelines that govern the use of the system.
