How Do Computers Represent Images

Have you ever been amazed by the high-definition graphics or beautiful pictures on your computer screen? It's all because of pixels, which are very small colour dots that make up pictures. Every pixel is a different colour, and your computer keeps track of these colours with numbers. It could, for instance, use three numbers to show how much red, green, and blue is in a pixel. This would make millions of colours possible! So, whether you're watching a movie or changing a picture, your computer's pixels make things come to life.
