AP COMPUTER SCI PRINC 1

A computing device is a physical artifact that can run a program. Which of the following is not an example of a computing device?

• Computer

• Router

• Tablet

• Notebook

An effect of a computing innovation can be viewed as both beneficial and harmful by different people, or even by the same person. Which of the following scenarios best illustrates this idea?

• A smartphone that allows for easy communication but can also lead to privacy concerns.

• A refrigerator that keeps food cold and fresh.

• A clock that tells time accurately.

• A car that can drive fast and has a comfortable interior.

Why is collaboration that includes diverse perspectives important in the development of computing innovations?

• It speeds up the development process by reducing the number of meetings.

• It ensures that the technology is developed only for a specific group of users.

• It helps avoid bias and creates more inclusive and effective solutions.

• It increases the cost of development due to more people being involved.

How do computing innovations impact society?

• They only affect people in the technology industry.

• They influence how people interact, communicate, work, and entertain themselves.

• They have no effect on how people communicate.

• They only improve gaming and entertainment experiences.

Why is collaboration important in the development and improvement of computing innovations?

• It allows a single person to control the entire development process.

• It helps reduce the overall cost of development by minimizing team sizes.

• It enables diverse teams to combine their unique skills, experiences, and perspectives, leading to more robust, efficient, and creative solutions.

• It ensures that only one perspective is considered, avoiding conflicts during development.

Why is it important to collect feedback from different users when developing a program?

• To increase the complexity of the program.

• To ensure the program addresses a wide range of needs, preferences, and challenges.

• To focus only on the most common user requirements.

• To avoid any changes to the original design of the program.

What is the relationship between data and information?

• Information is a random assortment of data without any meaningful patterns.

• Data is the final product derived from analyzing information.

• Information is the collection of facts and patterns extracted from data.

• Data and information are the same and can be used interchangeably.

What does abstraction in computer science involve?

• Ignoring all system details and not using any programming languages.

• Simplifying complex systems by focusing on essential features and hiding underlying details.

• Writing code only in low-level programming languages.

• Creating complex systems without any simplification.

Which of the following statements about compiling is not true?

• Compiling translates the entire source code of a program into machine code or intermediate code before execution.

• Compiling produces an executable file or bytecode that can be run independently.

• Compiling usually results in slower execution times because the translation happens multiple times during execution.

• Compiling requires the entire program to be compiled before running, which can be time-consuming.

Which of the following statements about interpreting is not true?

• Interpreting translates and executes source code line-by-line or statement-by-statement at runtime.

• Interpreting produces a separate executable file that can be run independently.

• Interpreting allows for immediate execution and easier debugging, as code is executed incrementally.

• Interpreting generally results in slower execution time compared to compiled languages, as translation occurs during execution.
