Start date

10 Weeks
Online Course


Learn how data is represented through media; audio, visual and text. This online course from the Raspberry Pi Foundation explores how computers do interesting things with data. You’ll discover how to represent and manipulate text, images and sound and compression and other algorithms.


You will:

  • Describe how computers represent things in binary.                                                                               
  • Explain common text encoding (ASCII and UTF-8).                                                                                 
  • Produce your own emoji in bitmap and vector form.                                                                              
  • Investigate the physics of sound, and how sampling allows computers to represent sounds.               
  • Compare lossy and lossless compression.
