AP Computer Principles Quiz

Collaboration can provide which of the following?

• Several points of failure

• Clean data

• Duplication of effort

• Better products resulting from different perspectives

What is a benefit of using a software development design process?

• By following the process, the code will work the first time.

• Using the process, the code will be efficient regardless of a programmer's experience.

• The code will be developed in 50% less time using a development/design process.

• The process is iterative, resulting in a better program.

Which of the following is not a common step in many software development processes?

• Designing

• Investigating

• Identifying patterns

• Testing

What do using surveys, interviews, and observations identify?

• Device specifications

• Program errors

• User requirements

• Valid program input

Why is documentation important?

• To explain a program's purpose and functionality

• To make it easier to understand and modify the code later

• To be useful for training people on how to use the program

• All of the above

Why should boundary values be tested?

• Testing boundary values is not necessary.

• To ensure they are identified as errors

• To ensure warning messages are sent about the boundaries

• To ensure the program does not include too few or too many elements

What is a crucial step in an iterative development process?

• Feedback

• Preparing prototypes

• Meeting deadlines

• Meeting budget constraints

What is a benefit of understanding a problem before coding?

• A better designed program is created to handle all the needed functionality.

• Less testing is required.

• Little or no documentation is then needed.

• Users will not need training to use the program.

Which phase in the development process determines how to meet the application requirements?

• Analysis

• Design

• Programming

• Testing

How do event-driven programs progress?

• They run in a linear fashion from start to end.

• The code executes sequentially.

• The code executes when an action occurs that it is programmed to recognize.

• The code runs iteratively.
