Decomposition and Abstraction (AQA GCSE Computer Science): Flashcards

Step-by-step instructions that tell a computer how to solve a problem

Algorithm is plan/recipe; program is implementation

Breaking big problems into smaller, manageable chunks

Focusing on important details, ignoring unnecessary ones

Make bed, put clothes away, clear desk, vacuum floor

Don't need to know circuits, just press buttons

Connections between stations & how lines intersect

Actual distances & real geographical layout

Team members work on different parts simultaneously

Smaller tasks are easier to test and debug

Manage complexity, work efficiently, reduce errors

Well-decomposed parts can be reused in other projects
