Which term means breaking down problems into smaller parts?

• A. Decomposition
• B. Flowchart
• C. Sequence
• D. Selection

Answer: (A)

Decomposition is breaking down problems into smaller parts. This approach makes a big task easier to manage by isolating subproblems you can design, implement, and test one at a time, then combine to form the full solution. For example, designing a library management system could split into user interface, search, checkout, and database access. The other terms describe different ideas: a flowchart is a visual map of steps in a process; sequence refers to the order in which steps occur; selection involves choosing between options based on a condition.
