Paper 1
Revise: Units of Data StorageMetadata is data about other data. A photograph may store its creation date, location or image dimensions alongside the image itself. This information takes up space too, so a calculation may include a metadata allowance.
Additional data about a file. For an image, this can include its width and height in pixels, colour depth and creation date.
Include metadata when an allowance is given. Do not invent an extra metadata size when none is supplied.
When defining metadata, say that it is additional data about the image, rather than the data representing each pixel’s colour.
