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

## Binary to hexadecimal conversion
A much simpler way to read binary data is by converting it to a hexadecimal number. Hexadecimal numbers group binary numbers into sets of four digits. Check your knowledge on binary to hexadecimal conversion by completing the exercise below. If you get it right, then move on to the next lesson, otherwise, refer to Table $1$, which shows the conversion between decimal, binary, and hexadecimal numbers. 

### Exercise: Join the codes
The left-hand side shows data in binary format, and the right-hand side shows data in hexadecimal format. Connect the binary numbers with their corresponding hex codes by dragging the connectors (■) from left to right.
