Exam-style question
Try this first
Explain how a bit pattern can represent a graphic. Include the role of an agreed representation in your answer.
Model answer
What a good answer should say
- A graphic can be encoded as a bit pattern using an agreed representation.
- The representation specifies how the bits should be interpreted as information about the graphic.
- When the bit pattern is read using that same representation, the stored data can be treated as a graphic rather than as an unrelated sequence of bits.
Explanation
Why this works
A strong answer states that the graphic is encoded into bits and that an agreed representation gives those bits their meaning. It should show that the bits are not meaningful in isolation.
