This Computer Memory Size Chart is a visual Computer Science poster for learning bits, bytes, KB, MB, GB, TB and storage units. Designed for GCSE and A-Level students, it makes computer memory sizes and data representation easier to understand and revise.
📘 A Common Question Explained
Is 1 MB equal to 1000 KB or 1024 KB?
Both interpretations exist:
Base 10 (Decimal): 1 KB = 1000 bytes
Base 2 (Binary): 1 KB = 1024 bytes
This resource explains both, helping students understand why the difference exists and how memory sizes are represented in Computer Science.
