Definition
A paradigm that organises a program as objects, created from classes, that hold data (attributes) and behaviour (methods) and communicate by passing messages.
Example: Contrast: procedural = a list of subroutines acting on separate data; OOP = objects that own their data and methods.
Found in: syllabus, school notes, past SDD papers.
Where you'll use it in the test
Syllabus area: Y11 OOP.
Question types it can appear in
- Multiple choice: Pick the option that matches the definition or example.

How to use it
A model sentence
“A paradigm that organises a program as objects, created from classes, that hold data (attributes) and behaviour (methods) and communicate by passing messages.” Then apply it: Contrast: procedural = a list of subroutines acting on separate data; OOP = objects that own their data and methods.
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.

Reveal the answer
A paradigm that organises a program as objects, created from classes, that hold data (attributes) and behaviour (methods) and communicate by passing messages.
Example: Contrast: procedural = a list of subroutines acting on separate data; OOP = objects that own their data and methods.

Quick multiple choice
Which OOP concept is shown when a class keeps its data private and exposes it only through methods?
- Polymorphism
- Inheritance
- Abstraction
- Encapsulation
Show the answer
D
Encapsulation bundles data with the methods that operate on it and restricts direct access.
