Try 2 sample questions on Hardware: primary memory (RAM and ROM) and secondary storage (types, characteristics and uses)

Question 1 · 1 mark · Difficulty 1/3

Which statement correctly describes a characteristic of ROM?

  1. ROM allows data to be written and overwritten repeatedly
  2. ROM is used as the main working memory during program execution
  3. ROM is volatile and loses its contents when power is removed
  4. ROM is non-volatile and retains its contents without power
Show answer & explanation
✓ Answer: D — ROM is non-volatile and retains its contents without power
ROM (Read-Only Memory) is non-volatile, meaning its contents are retained even when power is switched off. Option C describes RAM, not ROM. Option A describes RAM, which supports repeated read/write operations. Option B describes RAM, which serves as working memory for running programs.
Question 2 · 1 mark · Difficulty 2/3

Which type of secondary storage would be most suitable for distributing commercially produced software to customers?

  1. Solid-state drive installed in the computer
  2. Optical disc such as a DVD-ROM
  3. USB flash drive formatted as read-write
  4. Magnetic hard disk drive installed in the computer
Show answer & explanation
✓ Answer: B — Optical disc such as a DVD-ROM
A DVD-ROM is ideal for commercial software distribution because it is read-only (preventing unauthorised copying or modification), cheap to mass-produce, and portable. Internal HDDs and SSDs (options A and D) are not portable distribution media. A read-write USB flash drive (option C) allows unauthorised modification of software.

CIE IGCSE Computer Science: Hardware: primary memory (RAM and ROM) and secondary storage (types, characteristics and uses) FAQ

Is Kramizo free for CIE IGCSE 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 Hardware: primary memory (RAM and ROM) and secondary storage (types, characteristics and uses) practice with other Computer Science topics or even switch to a totally different CIE 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 Hardware: primary memory (RAM and ROM) and secondary storage (types, characteristics and uses) questions aligned to the official CIE IGCSE Computer Science syllabus?
Every question is written against the published CIE IGCSE 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 CIE 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 CIE.
How is Hardware: primary memory (RAM and ROM) and secondary storage (types, characteristics and uses) typically tested on CIE IGCSE Computer Science papers?
Hardware: primary memory (RAM and ROM) and secondary storage (types, characteristics and uses) appears across multiple question types on real CIE IGCSE 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.
