Which of the following is NOT a part of the information system?

The choice identifying "Weather" as NOT a part of the information system is accurate because, in the context of information systems, the primary components typically consist of people, data, and equipment.

People refer to the users and IT professionals who interact with and manage the system. Data is the raw information that is processed and analyzed to obtain valuable insights, while equipment includes the hardware and software necessary to run the information system effectively.

Weather, while it may be relevant to certain types of data analysis or information systems (such as those used in meteorology or environmental studies), does not inherently belong to the framework of an information system itself. It is an external factor or variable, not a structural component essential to the system’s operation, organization, or management.
