Which statement about Abstraction in programming is correct?

• A. It reduces information and detail to focus on essential characteristics
• B. It describes solutions to digital divide
• C. It governs copyright licensing
• D. It refers to network protocols

Answer: (A)

Abstraction in programming is about hiding the messy details and exposing a clean interface that shows only what’s necessary. By focusing on essential characteristics, you can reason about a system’s behavior without getting lost in how every part works internally. For example, when you call a library function, you use its inputs and outputs without needing to know the exact steps it takes inside. In object-oriented design, you interact with an object through its public methods while keeping internal data private; this separation lets you use and swap components without worrying about internals. The other statements touch on unrelated topics—solving the digital divide, copyright licensing, and network protocols—rather than what abstraction means in programming.
