The Computing Progression Pathways suggests that at the red level, on the theme of Data & Data Representation, a student should demonstrate that he/she:
- Understands how numbers, images, sounds and character sets use the same bit patterns. (Abstraction) (Generalisation)
- Performs simple operations using bit patterns e.g. binary addition. (Abstraction) (Algorithmic Thinking)
- Understands the relationship between resolution and colour depth, including the effect on file size. (Abstraction)
- Distinguishes between data used in a simple program (a variable) and the storage structure for that data. (Abstraction)

- Could you make the most powerful computer ever created … out of chocolates? It’s actually quite easy. You just have to have enough chocolates (and some lollies). It is one of computer science’s most important achievements.
