Introduction
One of the most underestimated parts of IB Computer Science is learning the key definitions and terms. From system fundamentals to networking and databases, the IB expects students to use precise wording. In fact, Paper 1 and Paper 2 often award easy marks for exact definitions — but only if you can recall them quickly and accurately.
If you’ve ever struggled to memorize long lists of terms, you’re not alone. The good news? With the right techniques, you can learn and retain definitions much faster. This guide will show you active memory strategies designed for IB Computer Science.
Quick Start Checklist
- Focus on syllabus command terms and definitions.
- Use active recall instead of re-reading notes.
- Break definitions into keywords, not full sentences.
- Use flashcards (physical or digital apps like Anki).
- Practice with past paper questions that require definitions.
Why Definitions Matter in IB Computer Science
- Many multiple-choice questions test direct definitions.
- Short-answer questions often start with “Define” or “Outline.”
- Examiners expect precision — vague wording won’t earn marks.
- Knowing terms makes it easier to tackle longer applied questions.
For example:
- “Define primary key.”
- “Explain the difference between RAM and ROM.”
- “Outline the purpose of the software development life cycle.”
Clear, concise answers here can build your score quickly.
Best Memory Techniques for Definitions
1. Active Recall with Flashcards
Write the term on one side and the definition on the other. Quiz yourself until you can recall quickly. Digital flashcards like Anki or Quizlet use spaced repetition, which helps you remember long-term.
2. Keyword Reduction
Instead of memorizing full sentences, break definitions into 3–4 key words. For example:
- RAM → “temporary, volatile, active programs.”
- ROM → “permanent, non-volatile, instructions.”
When you see the term, you can rebuild the full definition from keywords.
3. Use Mnemonics
Create simple memory tricks:
- OSI Model Layers → “Please Do Not Throw Sausage Pizza Away” (Physical, Data Link, Network, Transport, Session, Presentation, Application).
4. Mind Maps
Organize terms visually by theme: system fundamentals, networking, programming. Mind maps help you connect related concepts, making recall faster.
5. Teach Someone Else
Explaining a definition out loud forces your brain to structure it. Even five minutes of “teaching” can boost memory retention more than passive reading.
One-Week Definition Drill Plan
- Day 1–2: Focus on system fundamentals and hardware/software terms.
- Day 3–4: Revise networks and communication definitions.
- Day 5: Drill databases and SQL terms.
- Day 6: Revise SDLC and software design terms.
- Day 7: Full review with flashcards, timed recall, and practice with past papers.
Frequently Asked Questions
1. Do I need to memorize definitions word-for-word?
Not word-for-word, but close. Examiners expect key terms to be included. Leaving out crucial keywords can cost marks.
2. How many terms should I focus on?
Around 50–60 high-priority terms cover most of the syllabus. Use the IB Computer Science guide or RevisionDojo’s notes to identify the most important.
3. Are flashcards enough?
Flashcards are excellent, but combine them with practice in context. Use past papers to see how definitions appear in real exam questions.
4. What if I forget a definition during the exam?
Write down what you remember — partial knowledge can still earn marks. Use examples if possible to support your definition.
5. Should I spend more time on definitions or coding?
Both matter, but coding and algorithms carry heavier marks. Spend 20–30 minutes daily on definitions while focusing most of your time on practice problems.
Conclusion
Memorizing IB Computer Science definitions doesn’t have to feel overwhelming. With active recall, flashcards, mnemonics, and spaced repetition, you can lock in key terms quickly and recall them under exam pressure.
Definitions may seem small compared to coding or databases, but they often provide the fastest marks in the exam. Nail them, and you’ll start Paper 1 and Paper 2 with confidence.
