Study Notes

Input

Input involves collecting and gathering raw data.
Data sources include manual entry, sensors, and electronic devices.
Examples include keyboard input, scanning documents, and sensor data.
Ensuring input accuracy and completeness is crucial for subsequent steps.

Processing

Processing manipulates, calculates, and organizes input data.
This stage includes sorting, categorizing, calculations, and data conversion.
Examples include sorting orders by date, calculating totals, and converting analog to digital data.
Processing complexity varies based on the application.

Storage

Storage saves processed data for future use.
Storage methods include databases, cloud storage, and physical archives.
Examples include saving sales data in spreadsheets, storing customer data in databases, and backing up files.
Secure and accessible storage is vital to prevent data loss.

Output

Output presents processed and stored data in a meaningful format.
Output formats include reports, visual displays, and presentations.
Examples include generating sales reports, displaying customer trend graphs, and printing invoices.
Output clarity and conciseness are important for intended recipients.

Control

Control monitors and evaluates the entire information processing cycle.
Control ensures data accuracy, maintains system efficiency, and prevents errors.
Examples include auditing data entry and implementing maintenance schedules.
Control mechanisms identify and correct issues.

Feedback

Feedback is crucial in the information processing cycle.
Feedback reflects the impact of processed data, impacting input parameters, processes, storage, and future cycles.
Feedback formats include user comments, performance metrics, and comparisons.
Examples include user feedback on inaccurate reports or output enhancement suggestions.
Feedback allows modifications and refinements for a more efficient cycle resulting in higher-quality information.
