A Data Flow Diagram is used to summarise what?

• A. the flow of information around a system
• B. the hardware configuration
• C. the user requirements
• D. the software licensing

Answer: (A)

Data Flow Diagrams focus on how information moves through a system. They map the paths of data as it flows between processes, data stores, and external entities, showing how inputs become outputs and where data is kept. This makes them a concise summary of the flow of information around the system. They don’t depict hardware configurations, user requirements, or software licensing, which lie outside the diagram’s scope.
