Which of the following is NOT one of the four big ideas of AP Computer Science Principles?

The four big ideas of AP Computer Science Principles are essential concepts that help shape the understanding of computer science as a discipline. Creativity, abstraction, and data and information are all recognized as foundational aspects of the curriculum.

Creativity emphasizes the role of innovative thinking in programming and design, showcasing how technology can be used to create new applications and solutions. Abstraction involves reducing complexity by focusing on the relevant details of data and processes, allowing for more manageable solutions to complex problems. Data and information delve into how data is collected, processed, and analyzed, underscoring the importance of data literacy in today's digital age.

On the other hand, network security, while a significant topic within computer science, is not categorized as one of the four big ideas in AP CSP. It focuses more on the measures and practices employed to protect network integrity, data confidentiality, and system availability rather than serving as a foundational concept that underpins the entire study of computer science principles. This distinction clarifies why network security is not part of the core ideas that the AP CSP framework emphasizes.
