Which term describes the act of ignoring unnecessary details to focus on the essential parts?

• A. Abstraction
• B. Coding
• C. Processing
• D. Structure diagrams

Answer: (A)

Abstraction is about removing irrelevant details to focus on what matters. In algorithms and pseudocode, you model a problem at a high level, describing the essential steps and relationships without getting bogged down in low‑level how‑tos. This lets you think about the flow, inputs, outputs, and key actions without being distracted by every tiny implementation detail. For example, when outlining a search routine, you specify the idea of checking membership and moving to the next item, rather than specifying exactly how a check is performed. That focus on the big picture and essential parts is what abstraction is all about. Coding turns ideas into actual instructions, processing is the computer doing operations on data, and structure diagrams show how parts of a system relate, but none of those capture the act of trimming away non‑essential details like abstraction does.
