The Nature of Technology: Storing Digital Data
Computers store information using only two symbols — 0 and 1. In this unit, you will explore how text, pictures, and sound are represented as digital data. You will practise converting decimal numbers into binary and learn about how computers use codes to store text. You’ll also create simple digital images and understand how computers handle sound and video.
