Question 1 · 1 mark · Difficulty 1/3

Why do computers use logic gates?

  1. They store files permanently on the hard disk
  2. They connect the computer to the internet
  3. They display images and text on the screen
  4. They process binary signals to make decisions and perform calculations
Show answer & explanation
✓ Answer: D — They process binary signals to make decisions and perform calculations
Award 1 mark. Logic gates, built from transistors, combine binary signals; the CPU's arithmetic and decision-making are built from them.
Question 2 · 1 mark · Difficulty 1/3

What is the output of an OR gate when both inputs are 0?

  1. 1, because OR reverses the inputs
  2. 0, because neither input is 1
  3. 1, because both inputs are equal
  4. 0, because OR only works on 1s
Show answer & explanation
✓ Answer: B — 0, because neither input is 1
Award 1 mark. OR needs at least one input to be 1. With both inputs 0, the output is 0.

OCR GCSE Computer Science: Computational Logic FAQ

Is Kramizo free for OCR GCSE students preparing for Computer Science?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Computational Logic practice with other Computer Science topics or even switch to a totally different OCR subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Computational Logic questions aligned to the official OCR GCSE Computer Science syllabus?
Every question is written against the published OCR GCSE Computer Science specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real OCR paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from OCR.
How is Computational Logic typically tested on OCR GCSE Computer Science papers?
Computational Logic appears across multiple question types on real OCR GCSE Computer Science papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
