​Images

Images are made of tiny elements called pixels (picture elements). The higher the number of pixels the higher the resolution of the image will be, hence, more memory is occupied by the image. Image files can be bitmaps or vectors. In this article, we learn about the different types of images, its properties such as colour depth and resolution, how an image is stored in a computer, how images are displayed, and metadata of an image.

This GCSE Computer Science module introduces ​images to your students, explaining:

  • ​Different types of ​image format
  • How ​to store and display images
  • Estimating the size of image file
  • Definition of metadata
