About this unit
This unit explains how computers store information digitally, as binary data. Learn about the binary number system, the conversion of analog to digital data, and data compression strategies. With more than 100 questions, you can practice what you've learned and study for the AP Computer Science Principles exam.AP® is a registered trademark of the College Board, which has not reviewed this resource.
