Memory Size Chart Poster – Bits, Bytes & Storage Units

Memory Size Chart Poster – Bits, Bytes & Storage Units (1000 vs 1024)

A clear memory size chart revision poster designed to support students learning about data representation and storage units in Computer Science. The poster condenses key information into a single page, making it ideal for regular visual reference in the classroom.

This resource explicitly addresses the common exam-area confusion between base 10 (1000) and base 2 (1024) interpretations of memory sizes.

What this resource covers:

Bits and bytes

Kilobytes, megabytes, gigabytes (and beyond)

The difference between 1000-based and 1024-based memory units

Clear comparison to support exam understanding

What’s included:

1 memory size chart using the 1000-based (decimal) interpretation

1 memory size chart using the 1024-based (binary) interpretation

This allows teachers to explicitly teach both conventions and clarify which is expected in different contexts and examinations.

Suitable for:

Computer Science classrooms

GCSE revision

KS3–KS4

Display boards or revision walls

Educational value:

Supports understanding of a key GCSE Computer Science concept

Reduces misconceptions around memory units

Encourages passive revision through regular exposure

Ideal for last-minute exam reinforcement

Format:

JPEG files

Provided in two ZIP folders (1000-based and 1024-based)

Sizes included: A4, A3, A2 and US Letter

Suitable for printing or laminating
