What does the 'input' task performed by an information system involve?

The 'input' task performed by an information system primarily involves the acquisition of data. This stage is critical because it is where raw data is collected and entered into the system for processing. This data can come from various sources, such as user entries, sensors, external databases, or other information systems. Proper acquisition is vital as it sets the foundation for data processing, analysis, and ultimately decision-making within the information system.

In contrast, sorting of data pertains to organizing data for easier access and analysis, which occurs after data has been inputted into the system. Outputting data involves generating reports or visualizations based on processed data, and disposing of data relates to data management practices concerning the deletion or archiving of information. Thus, acquisition is the initial critical step that enables all subsequent operations within an information system.
