Computer systems do not understand human instructions, nor can they perceive real-life data in its raw form. Therefore, computer systems require a way to store and represent information in an accessible way. They use software and hardware components combined to help retrieve information, store it, manipulate it, and convert it back to a human-accessible format. If you want to learn how computer systems perform complex tasks such as storing and manipulating textual data, videos, music, images of your cat, and much more, this course is meant for you.

Information Representation in Computer Systems

## Exercise: Color the pixels

Create a video with 50 frames, where each pixel in every frame has a random colour. This can be achieved by three nested for loops. Set the default frame size to 100 $\times$ 100 pixels and set the default frame rate to 10 frames per second. Your code should return a video which is 5 seconds long. Download and play `exercise2.mp4` to verify your result.
