Match each software design concept with its defining characteristic: Concepts: 1. Abstraction 2. Modularity 3. Software architecture 4. Documentation Characteristics: A. High-level structure, components, and relationships of a complete system B. Simplifying complexity by focusing on essential features while suppressing lower-level details C. Decomposing a system into distinct, self-contained units with defined interfaces D. Written records and diagrams detailing how a system is designed, implemented, or operated

### Why this is right These concepts describe different ways to understand and organize a design: abstraction controls detail, modularity separates parts, architecture describes high-level structure, and documentation records information. ### The pairs | Item | Matches | Why | |---|---|---| | Abstraction | Representing essential features while setting aside detail | It lets designers reason about a system without considering every implementation detail at once. | | Modularity | Organizing a system into distinct parts | Parts can be considered and developed as identifiable units. | | Software architecture | High-level structure of a software system | It describes the major elements and their organization. | | Documentation | Recorded information about the software or its design | It communicates information to users, developers, and maintainers. | ### Remember Abstraction hides detail; modularity separates parts; architecture organizes the whole.
