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.

What topics will you cover?

  • Units of information
  • Character encoding
  • Representing images
  • Representing sound
  • Data compression

What will you achieve?

By the end of the course, you'll be able to...

  • 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.

Who is the course for?

This course is designed at GCSE-Level to A-Level educators and learners. This course has a focus on supporting educators looking for an engaging way of teaching GCSE Computer Science concepts.

We recommend that learners have a basic understanding of Python, for example gained from our Programming 101 course for beginners

An understanding of binary is helpful but not necessary (you may be interested in our How Computers Work course)

Due to its section on the representation of images, this course includes several steps and questions based around visual content.

What software or tools do you need?

To take part in this course you will need to download a Python IDE (Integrated Developer Environment) such as Mu.
