Storage — 20 Exam-Style Questions

20 exam-style questions on storage for OCR GCSE Computer Science (J277/01), with full answers and guidance.
Covers both primary and secondary storage — RAM, ROM, virtual memory, cache, and all three types of secondary storage (magnetic, solid state, and optical) — with questions modelled on the style and command words used in actual J277 papers: complete the table, identify the error, explain, evaluate, and a scenario-based justify question worth 4 marks.
Includes:

40 marks across 20 questions, split into three progressive sections
Scenario questions with data tables, matching the real exam format
Answers written for students, not teachers — no “award 1 mark” language
Watch out boxes targeting the specific misconceptions flagged in OCR examiner reports (including the “secondary storage fills when RAM is full” error, the solid state longevity myth, and RAM/ROM confusion in virtual memory)
Stretch & challenge questions to deepen understanding without going beyond the spec

Print-ready and suitable for independent revision, structured practice, or classroom use.
