Dfd diagram of training and placement cells?

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.)
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.
Discuss the components of information systems?
· Information systems consist of three components. They are the human being (in other words, the user of the information system), the task and the application system. In this context, the term information system is defined in terms of the three levels of semiotics. It is easier to process data automatically with the help of an application system which corresponds to the syntax level. The syntax level is defined as the first level of semiotics in terms of which an information system is defined. In the context of an individual user of an information system who interprets the data, they become information which corresponds to the semantic level. The semantic level is defined as the second level of semiotics in terms of which an information system is defined. Information turns to knowledge when an individual knows or understands and evaluates the information (for instance, the information for a specific task). This corresponds to the pragmatic level. The pragmatic level is defined as the third level of semiotics in terms of which an information system is defined. mcezra1@gmail.com +260974386858 Kafue, Zambia , Kafue Child Development Agency (KCDA) an affiliate of ChildFund Zambia.
