Question

In a DFD, a data destination is represented by ______

A. A bubble
B. Two horizontal lines
C. An arrow
D. A square

Answer 1

In a DFD, a data destination is represented by a square, differentiating it from other elements such as processes, data stores, and data flows.

Step-by-step explanation:

In a Data Flow Diagram (DFD), a data destination is represented by D. A square. The elements in a DFD include processes (bubbles), data stores (two horizontal lines), data flows (arrows), and entities or data destinations/sources (squares or rectangles).

The use of a square denotes an external entity to which data is going (or from which data is coming), distinguishing it from processes that transform the data.
