In a Data Flow Diagram (DFD), a single arrow represents the flow of data between processes, data stores, and external entities. It indicates the direction of data movement, showing how information is transmitted from one component to another. This helps in visualizing the system's data flow and understanding how inputs are transformed into outputs within the system.

What is top down approach in DFD?
The top-down approach in Data Flow Diagrams (DFD) involves breaking down a system into its high-level components and then progressively detailing each component into smaller, more specific processes. This method starts with a broad overview of the system, represented by a high-level DFD, and gradually refines it into lower-level diagrams that illustrate the specific data flows and processes. This hierarchical structure helps in understanding the overall system while ensuring clarity and organization in design. It is particularly useful for identifying relationships and interactions within complex systems.
Differences between NFA and DFA and Compare their powers as a token recogniser?
1. Every state of DFA always has exactly one exiting transition arrow for each symbol in the alphabet. In NFA a state may have zero, one or many exiting arrow for each alphabet. 2. NFA can use empty string transition but DFA can not use it.
What is the Difference between physical DFD and logical DFD?
For a physical Data Flow Diagram you explore into the logical DFD. for example, if you have a data flow arrow declared as "customer information" now the physical DFD would include in that data flow arrow "customer information = customer_name + customer_address". something along these lines Physical DFD shows how various functions are performed and who does them but Logical DFD strips away all physical constraints but does not restrict physical happenings from taking place.
