they are not different they are similar as level 0 DFD represents the primary individual process in system at highest level it is also called context diagram. It describes the overall system at highest level describing which element is inside and which element is outside the system.....

What is the relationship between a context diagram and diagram 0?
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.

What is the difference between conceptual class Diagram and Design level class Diagram?

What is the role of context diagram in requirement analysis?
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.
Why does a context diagram not show data stores?
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.
What does the context-level data flow diagram?
the system entities and how they are related
What is a context level diagram?
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.)
Context level diagram for import export systems?
The context diagram is very important part in FDD which stands for functional Decomposition Diagram. It will help us to create the baseline in context diagram which we will draw the entities and the main process. Thus we have knowledge what Diagram Zero DFD contains, which is the same entities and same data flow but only the processes will break down into the lower sub process.

What is the difference between a use-case diagram and class diagram?
Class diagram is UML structure diagram which shows structure of the designed system at the level of classes and interfaces, shows their features, constraints and relationships - associations, generalizations, dependencies, etc.Communication diagram (called collaboration diagram in now obsolete UML 1.x) is an interaction diagram which shows interactions between objects and/or parts (represented as UML lifelines) using sequenced messages in a free-form arrangement.So, the major difference is that class diagram shows static structure of the system while communication (collaboration) diagram shows system behavior as sequenced exchange of messages between objects.
