Which of the following is NOT an input for an information system?

An input for an information system refers to any device or method that can gather or send data into the system for processing. In this context, the correct answer is A, the digital dashboard, because it is primarily a display interface designed to present information rather than to input data. Digital dashboards are utilized to visualize data in a user-friendly manner, providing insights and overviews based on data that has already been processed.

In contrast, handheld computers, bar-code scanners, and cell phones are actively used to input data into an information system. Handheld computers allow users to enter information directly, bar-code scanners read bar codes to input specific product information, and cell phones can capture data through various applications or features, thus serving as tools for data input in various contexts.
