Q: Match the endings with the correct sentences.
- Images can be stored in different ways on a computer. When you create a drawing in PowerPoint this is called | a vector graphic
- These drawings are made up of lines with specific properties such as line style, line colour, where it starts and where it ends. The computer will store all of this data about each line using | binary
- When you take a photograph on a digital camera it is processed as | a bitmap image
- Before this type of image can be stored on a computer the image has to be broken down into very small elements, each of these is called | a pixel
- As an example, the whole image may be 600 elements wide by 400 elements deep. The measurement 600 x 400 are referred to as | an image resolution
- If the measurements of a picture is increased, then more elements will need to be stored. This increases the size of | an image file
- Important information about the bit depth and resolution is stored inside an image file, this is called | metadata
Also offered: file compression; mixed media

Q: If the colour depth of a bitmap image is increased to improve the image quality, it means that less bits are used to represent each pixel, so the overall size of the file will be reduced meaning smaller file sizes.
- True
- False
A: False

Q: Sometimes the resolution of a bitmap image is reduced to improve the image quality, however reducing the resolution means that more bits are required to represent each pixel, so the overall size of the image file will be increased meaning larger file sizes.
- True
- False
A: False
