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

## Lossless compression
Unlike lossy compression, lossless compression does not delete or distort any information. There are a few common lossless compression algorithms applied to text and images. Let's look at them one by one.
