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.....

high level language are easier to learn
There is a big difference between height and elevation. Height is how tall something is. Elevation is how far above sea level something is.

Algebra 1 is a class/course that is on a higher level than Algebra.
There's no such thing as Algebra 3Edit: Yes there is. It is a college level course and when it is offered in high school it's called Algebra Three. The difference is that Algebra 3 is more in depth than Algebra Two is.
context diagram, logical level 0 diagram and logical level 1 diagrams
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.
one is a diagram like a chart or graph, and one is a design like a blue print
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.)
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 elementary and basic
There are mainly three types of d.f.d. 1) top level d.f.d. 2)context level d.f.d. 3) exploded level d.f.d.
difference between business level strategy and corporate level strategy?
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.
