Study Notes
Feedback Loop
- In a feedback loop, the system's outputs are evaluated to ensure they meet the organizational goals.
- The system's outputs can be used as inputs to generate new information (e.g., student names and final results).
- Outputs can also be used as inputs for other systems (e.g., production system information showing what the factory produced, serving as input for the warehouse system to determine company stock).
Characteristics of Information Systems
Speed
- Information systems can quickly input, process, and display information, surpassing human capabilities.
Accuracy
- System outputs are accurate and error-free, unlike human outputs, which can be prone to errors due to fatigue, exhaustion, or other factors.
Storage
- Information systems can store large amounts of data and information in a relatively small space, allowing for quick retrieval when needed.
- This is achieved through the use of multiple storage media, enabling storage in multiple locations simultaneously, which helps protect data and information from natural disasters.
