What to revise

Practise types of processor.

Start with these questions from the types of processor topic pack. In the workspace, explain each idea from memory, compare your reasoning with the feedback, then revisit the concepts that need practice.

Use the pack alongside your OCR H446 computer systems revision. Your self-reported confidence helps plan the next review; it is not an exam mark or predicted grade.
