Final answer:
The correct sequence of components in the functional model of an information system is Input, Processing, Output. This reflects that data is first input, then processed, and finally output to users as meaningful information.
Step-by-step explanation:
The sequence of components in the functional model of an information system is typically: Input, Processing, and Output. This sequence reflects the order in which data is handled in an information system: first, data is entered into the system (Input), then the data is manipulated or processed to create meaningful information (Processing), and finally, the information is presented or otherwise made available to users (Output). Therefore, the correct answer to the question is option 1) Input, Processing, Output.
The explanation provided reflects the typical functioning of information systems and is similar to other sequential processes, including memory encoding and retrieval as well as design processes. In design processes, different steps follow one another; however, the process can be iterative as well, reflecting a spiral design process. Nonetheless, this iterative nature does not disrupt the basic understanding of the input-processing-output model in information systems.
