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: From white to black
Create a grayscale video that starts with the color white and ends on the color black. Set the default frame size to 400 $\times$ 400 pixels and set the default frame rate to 20 frames per second. Download and play `exercise1.mp4` to verify your result.
