context-free-diagramis a diagram that represents the actors outside a system that could interact with that system.
supervisory control and data acquisition
A context diagram shows the system as a single process with interactions between it and external entities, while a diagram 0 (also called a level 0 data flow diagram) expands on the context diagram by breaking down the system into more detailed processes and data flows within the system itself. The context diagram provides an overview, while the diagram 0 provides a more detailed look at how the system functions internally.
A context diagram focuses on showing interactions between a system and external entities, such as users or other systems, without detailing the internal workings. Data stores are considered internal to the system, so they are not shown in a context diagram to keep the diagram simple and to maintain a high-level view of the system's boundaries and connections.
the system entities and how they are related
context diagram shows the system under construction as a single high-level process and then shows the relationship that the system has with other external entities (system, organizational groups, external data stores, etc.)

In a context diagram, specific symbols like the data flow arrows, external entities (represented as rectangles), and the system boundary (often a circle or rectangle) are commonly used. However, symbols such as database icons or detailed process symbols are not included, as a context diagram focuses on high-level interactions rather than internal system details.
Context Diagram is higher level of abstraction of the whole system. It depicts the various subsystems that interact with each other along with major actors involved. It also gives you what information flows between the modules, actors and system at a high level.
