A real question from the Oxford, Cambridge and RSA (OCR) GCSE Computer Science Paper 2 Practice bank. Answer it, see the explanation, then decide.

Multiple Choice

How many megabytes are there in one gigabyte?

Explanation:
One gigabyte is equivalent to 1024 megabytes. This is based on the binary system used in computing, where storage capacities are measured in powers of two. In this system, one kilobyte equals 1024 bytes, one megabyte equals 1024 kilobytes, and therefore, one gigabyte is calculated as: 1 GB = 1024 MB. The options presented do not reflect this accurate mathematical relationship. Hence, the correct answer indicates that there are 1024 megabytes in one gigabyte, confirming the importance of understanding binary measurements in computer systems.

    I'm currently studying for my GCSE in Computer Science and using the app has been a game-changer. The flashcards help reinforce my memory, and though there's no structure, I like that I can focus on my weak areas through random questions. But I do wish there were some modules to guide my learning better. Still, great resource! 4/5.
