Explore how computer systems store, manipulate, and convert various data types like text, images, and videos through integrated software and hardware. Gain insights into accessible data representation.

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: The invisibility spell

Figure 1 shows images of a white cat and a black and white surface.

In the exercise below, you are given the two images as two-dimensional NumPy arrays. Your job is to perform bitwise AND at every pixel position and make the left half of the cat disappear as shown in Figure 2. 

Write your code in the `vanish` function. Store the resulting image in `im2`. Run the code once without modifying anything to display the original image.
