Which term describes representing or storing information with methods that separate layers of concerns so that the programmer can work with information while ignoring lower-level details about how the information is represented?

• A. Abstraction
• B. Data Abstraction
• C. Abstraction Hierarchy
• D. Creative Commons

Answer: (B)

The idea being tested is hiding how data is stored and focusing on how you interact with it. Data abstraction is the practice of defining data in terms of what operations you can perform on it and what the data represents, while concealing the underlying storage and representation details. This lets you work with information at a higher level, using a clear interface without needing to know whether it’s stored as memory structures, files, or databases. Abstraction alone is broader and could apply to processes or systems in general; abstraction hierarchy refers to levels of abstraction within a system, not specifically to data storage, and Creative Commons is unrelated licensing.
