Question 1

6.The value of a global variable is available to all other modules.

Accepted Answer

A global variable can be accessed and modified by any module that has access to it. This can be useful for sharing data between modules or for creating a configuration setting that is used throughout the application. However, it is important to use global variables carefully and avoid overusing them, as they can lead to unexpected behavior and make it difficult to track down bugs.

Question 2

15.The data dictionary is:&#10;A)A list of definitions of words used in the development of the solution.&#10;B)A list of definitions and attributes of the variables used in the solution.&#10;C)A table the computer uses internally to define the memory location of the variables.&#10;D)A table of values to test the solution of the problem.

Accepted Answer

The data dictionary is a document that defines the meaning and attributes of the variables used in the solution. It helps to ensure that everyone involved in the development process has a clear understanding of the data being used. A data dictionary typically includes definitions, data types, allowed values, and other relevant information about each variable. It is an important tool for maintaining consistency and accuracy in data analysis and management.

Question 3

24.The case logic structure within the decision logic structure:&#10;A)Processes instructions in order of listing.&#10;B)Allows the computer to make a choice of two paths to follow.&#10;C)Allows the computer to repeat instructions.&#10;D)Allows the computer to make a choice of two or more paths to follow.

Accepted Answer

The case logic structure allows the computer to make a choice of two or more paths to follow. This is useful when there are multiple conditions that need to be evaluated and different actions need to be taken based on those conditions. Therefore, option D is the best choice. Options A and C are incorrect because they only allow for sequential processing and repetition, respectively. Option B allows for a choice between only two paths, which may not always be sufficient.

Question 4

7.A solution is just as easy to read and understand if it is written in one module or many modules.

Accepted Answer

A solution can become harder to read and understand if it is divided into too many modules, making it difficult to follow the flow of the code. However, breaking up a large and complex solution into smaller modules can make it more organized and easier to read and understand. Therefore, it depends on the specific situation and the approach taken by the developer.

Question 5

18.Calculations may be found:&#10;A)In any module.&#10;B)Only in the calculation modules.&#10;C)Only in any process modules.&#10;D)Any module but the Wrap-up module.

Accepted Answer

Calculations can be found in any module as they are a fundamental aspect of the modeling process in any module. However, the Wrap-up module is used solely for documentation and reporting purposes and does not contain any calculations.

Question 6

8.The use of modules many times eliminates rewriting the same instructions.

Accepted Answer

This is because modules allow for the creation of reusable code that can be called multiple times without the need to rewrite the same instructions. This saves time and effort while also making the code more efficient and easier to maintain.

Question 7

4.The value of a local variable is available to all other modules.

Accepted Answer

The value of a local variable is only available within the module or function where it is defined. It cannot be accessed by other modules or functions.

Question 8

Cohesion relates to:&#10;A)The ability to share data between modules.&#10;B)The ability to have local variables shared between modules.&#10;C)All of the above.&#10;D)The functional independence of each module.

Accepted Answer

Cohesion relates to the functional independence of each module and the ability to share data between modules.
