AP CSP Programming Basics

Which of the following statements describes a limitation of using a computer simulation to model a real-world object or system?

• Computer simulations can only be built after the real-world object or system has been created.
• Computer simulations only run on very powerful computers that are not available to the general public.
• Computer simulations usually make some simplifying assumptions about the real-world object or system being modeled.
• It is difficult to change input parameters or conditions when using computer algorithms.

What is true regarding programming documentation (use of comments, notations, etc.)

• It should not be changed after it is first written.
• It helps during initial program development and also when modifications are made
• It is only needed during program development, not after completion
• It is only useful for collaboration, not independent programming.

Which of the following is an example of abstraction?

• Writing a function for code you repeat often
• Using logic symbols like < and >
• Numbers are converted from one base to another
• There is an error in the code

A programmer is writing a system that is intended to be able to store large amounts of personal data. As the programmer develops the data system, which of the following is LEAST likely to impact the programmer's choices in designing the structure of the system?

• Maintaining privacy of the information stored in the data set. 
• Scalability of the system. 
• Structuring the metadata of the information for analysis. 
• The frequency of a particular item occurring in a data set.
