Term Key terms bank Y11 OOP
Definition
Bundling an object's data and the methods that use it together in a class and restricting direct access to the data (private attributes, accessed through methods) so it stays valid and secure.
Example: Make balance private and change it only through deposit() so it cannot be set to a negative number directly.
Found in: syllabus, course specifications, school notes, past SDD papers.
Data and methods bundled and protected.

How to use it in an answer
A model sentence
“Bundling an object's data and the methods that use it together in a class and restricting direct access to the data (private attributes, accessed through methods) so it stays valid and secure.” Then apply it: Make balance private and change it only through deposit() so it cannot be set to a negative number directly.
In a short answer, give the definition in your own words first, then tie it to the situation in the question. Do not copy the example above unless it fits the scenario.
Command words used with it
No linked question shows the command word for this term. Across the past short answer questions in this bank the words used most are: Explain, Outline, Describe, Compare, Classify, Analyse. Check the actual word in your question.
Technique for the question types
- Multiple choice: Read all four options, rule out wrong ones, pick one; no penalty for guessing so never leave blank.
- Matching or table: Tick or match each statement to the right column (for example ORM v SQL, SAST v DAST).
- Short answer: One clear point per mark, use the stimulus and course terms, and answer the command word.
- Fill in the blanks: Choose the right word from a list; use exact syllabus terms.
Common mistakes
- Use the term exactly as the syllabus words it, then link it to the scenario in the question; the 2025 feedback repeatedly rewards using the stimulus.
- Answer the command word: outline gives main points only, explain gives a reason or cause, discuss gives both sides.
