Which term means hiding details to focus on important parts?

• A. Structure diagrams
• B. Abstraction
• C. Inputs
• D. Outputs

Answer: (B)

Abstraction is the idea of hiding details and focusing on what matters. In algorithms and programming, it means modelling a problem by keeping only the essential features and ignoring the rest. For example, when you use a calculator, you don’t need to know how the hardware adds numbers; you just perform the operation. Or think of driving a car—you use steering and pedals without needing to understand the engine internals. This focus on the important parts is what abstraction is all about. Structure diagrams show how different parts of a system are arranged and connected, not the act of simplifying details. Inputs are the data you feed into a process, and outputs are the results you get. Those concepts describe data flow or structure, not the pruning of details.
