What are the four basic elements of a data flow diagram?
-
Data sources and destinations, in flows, out flows and storage.
-
Data sources and destinations, data flows, transformation processes and data stores.
-
Data stores and destinations, transforming processes and data flows.
-
Data processes, data flows, storage and destinations.
Correct Answer
A. Data sources and destinations, data flows, transformation processes and data stores.Explanation
The correct answer is "Data sources and destinations, data flows, transformation processes and data stores." This is because a data flow diagram (DFD) is a visual representation of the flow of data within a system. Data sources and destinations represent where the data comes from and where it goes to. Data flows show the movement of data between different components. Transformation processes represent the actions or operations performed on the data. And data stores are used to store and retrieve data within the system.Rate this question:

What do the circles on a data flow diagram represent?
-
Data sources and destinations
-
Data flows
-
Data stores
-
Transformation processes
Correct Answer
A. Transformation processesExplanation
The circles on a data flow diagram represent transformation processes. These processes are responsible for converting inputs into outputs by performing various operations or calculations on the data. They can include activities such as data manipulation, data validation, data transformation, or data enrichment. The circles visually depict the stages where the data is being transformed or modified within the system.Rate this question:

Document flowcharts are often called:
-
Data flow diagrams
-
Internal control flowcharts
-
Process flowcharts
-
Multipurpose flowcharts
Correct Answer
A. Internal control flowchartsExplanation
Document flowcharts are often referred to as internal control flowcharts because they are used to visually represent the flow of documents within an organization's internal control system. These flowcharts help to identify and analyze the controls in place to ensure the accuracy, completeness, and reliability of documents as they move through various processes and departments.Rate this question:

A flowchart is
-
An analytical technique used to describe the data flows and sources and destinations and data stores of a system.
-
An analytical technique used to describe some aspect of an information system in a clear, concise, and logical manner.
-
A piece of hard plastic used to draw symbols.
-
A graphical description of the flow of data within an organization and the processes performed on that data, as well as the sources and destinations of data.
Correct Answer
A. An analytical technique used to describe some aspect of an information system in a clear, concise, and logical manner.Explanation
A flowchart is an analytical technique used to describe some aspect of an information system in a clear, concise, and logical manner. It is a visual representation that allows for the understanding of how data flows within an organization, including the processes performed on that data and the sources and destinations of the data. This technique helps to analyze and communicate complex systems in a simplified and structured way.Rate this question:
