What is the purpose of 'ASCII'?
Which of these text representation systems can represent the most characters?
The number of bits used to identify each colour in a bitmap
The number of pixels that make up an image. Measured by calculating image width x height
Explain how resolution and colour depth can affect the quality and file size of an image.
NOTE: There are 4 marks available for this question. You will need to be able to identify 1 impact on quality and 1 on file size, and for each you need to explain what the impact is.

What is meant by iteration?
Iteration allows us to simplify our algorithm by stating that we will repeat certain steps until told otherwise. This makes designing algorithms quicker and simpler because they don’t have to include lots of unnecessary steps. Iteration is often called
