Answer 1

In a Data Flow Diagram (DFD), both the data source and the data destination are represented by a square, indicating external entities to the system.

Step-by-step explanation:

In a Data Flow Diagram (DFD), the data source is typically represented by a square, and the data destination is represented by a square as well. These squares are sometimes referred to as external entities or terminators, and they symbolize where the data originates from and where it is going to outside the system being diagrammed. The use of the same shape for both source and destination emphasizes that these are entities outside the control of the system being analyzed.
