Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The system boundary and external entities that interact with it
A context diagram defines the system boundary and external entities that interact with the system. It is a high-level data flow diagram that focuses on external interactions rather than internal processes. Option A is incorrect because a context diagram does not show internal architecture; that would be a system architecture diagram. Option B is incorrect because sequence of interactions is depicted in a sequence diagram, not a context diagram. Option D is incorrect because detailed processes and data flows are shown in lower-level data flow diagrams, not the context diagram.
