What differentiates a context diagram from a process flow diagram?

• A. A context diagram depicts data flows without sequences. A process flow diagram depicts the processes with sequences.
• B. A process flow diagram depicts data flows without sequences. A context diagram depicts the resulted processes.
• C. A context diagram includes sequences while a process flow doesn't.
• D. A process flow has data outputs only, whereas a context diagram includes internal processes.

Answer: (A)

A context diagram serves as a high-level visual representation of an entire system and illustrates how it interacts with external entities—such as users or other systems—by showing the flow of data between them. It does not focus on the specific order of processes or the internal workings of the system; instead, it emphasizes the relationships and data exchanges without detailing the sequence of operations. In contrast, a process flow diagram provides a more detailed depiction of the internal processes within a system, illustrating how inputs are transformed into outputs through various stages. This diagram emphasizes the sequence and progression of tasks, detailing the steps involved in each process. Thus, the differentiation is clear: the context diagram captures the big picture without delving into the sequencing of steps, while the process flow diagram highlights the exact sequence and operational flow of processes within the system. This distinct focus makes the first option the correct choice.
