Help students understand computer memory sizes, storage units and data representation with this set of printable Computer Science revision posters.
The charts show the relationship between bits, bytes, kilobytes, megabytes, gigabytes and terabytes, including both decimal (1000-based) and binary-style (1024-based) conversions.
Designed as a quick visual reference for GCSE and A-Level Computer Science, the posters are useful for revision, classroom displays and data representation lessons.
Format, Theme, Use & Audience
Format: Digital printable Computer Science revision posters supplied as high-quality JPEG files.
Theme: Computer memory, storage units, bits and bytes, data representation and binary.
Use: Ideal for Computer Science classrooms, revision walls, data representation lessons, computer labs and student reference.
Audience: GCSE and A-Level Computer Science students, secondary Computing teachers and revision learners.
A Common Question Explained
Is 1 MB based on 1000 KB or 1024 KB?
You may see both approaches used in Computing:
Decimal / base 10: units increase in multiples of 1000
Binary-style / base 2: units increase in multiples of 1024
The two included charts let students compare both conventions and understand why different values may appear in Computer Science and technology contexts.
