In computer based information system (CBIS), DFD stands for: A. data flow diagram B. data flow descent C. dotted flow diagram D. such a terminology does not exist in CBIS E. None of the above

data flow diagram
data flow descent
dotted flow diagram
such a terminology does not exist in CBIS E. None of the above

The correct answer is A. Data Flow Diagram.

A data flow diagram (DFD) is a graphical representation of the flow of data through an information system. It is a tool that can be used to model the system’s data, processes, and data stores. DFDs are typically used in the early stages of system development to help understand the system’s requirements and to identify potential problems.

Option B is incorrect because data flow descent is not a term used in CBIS.

Option C is incorrect because dotted flow diagram is not a term used in CBIS.

Option D is incorrect because such a terminology does exist in CBIS.

Option E is incorrect because the correct answer is A.
