The purpose of information hiding is to
-
Create module
-
Make nonessential details transparent to the user
-
Reduce the details the programmer has to worry about at any given level
-
Tell us that related modules should be in the same physical part of the program
Correct Answer
A. Make nonessential details transparent to the userExplanation
The purpose of information hiding is to make nonessential details transparent to the user. This means that the user does not need to be concerned with the inner workings or implementation details of a module. By hiding these nonessential details, it allows for easier understanding and use of the module, as the user can focus on the essential functionality without being overwhelmed by unnecessary information. Additionally, information hiding also helps to reduce the details that programmers need to worry about at any given level, allowing for more efficient and manageable development.Rate this question:

Data flow is processed as it is received; however, data in a data store can be accessed at any time and in any order
Correct Answer
A. Data flow is processed as it is received; however, data in a data store can be accessed at any time and in any orderExplanation
The DFD ordering rule states that data flow is processed as it is received, meaning that it is processed in the order it arrives. However, data in a data store can be accessed at any time and in any order, indicating that there is no specific order in which data in a data store needs to be accessed. This rule helps ensure that the flow of data within a system is efficient and follows a logical sequence.Rate this question:
