Marks and feedback are AI-generated guidance for revision. CodeExam is an independent platform and is not an official exam-board marking service.

Exam-style question[4 marks]

Explain why virtual memory is used.

Your answer

“Virtual memory is used when RAM is full. It uses the hard drive to store data so programs can continue running.”

AI ExaminerAI-generated feedback
0 / 4Suggested mark
  • RAM becomes insufficient / full
  • Uses secondary storage
  • Allows programs to continue running
  • Doesn’t clearly explain that storage is used as additional temporary memory
How to get 4/4

Mention that part of secondary storage is used as temporary memory when physical RAM is insufficient.
