About Course

Raspberry Pi Foundation

Description

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.

Who will you learn with?

Mac Bowley

Hey, my name is Mac. I am a Learning Manager at The Raspberry Pi Foundation. I love teaching and digital making, especially when I get to do them both at the same time.

It's great that instructor Mac Bowley can make a technical class like this so interesting. I love it.

This is a technical course that I think you can take, and it's something that we'll use in our work. For example, how to represent and manipulate text, images and sounds, compression, and so on. Not bad.

It's great that instructor Mac Bowley can make a technical class like this so interesting. I love it.

The course was fun and taught me a lot about how to present data, audio, visual and text through the media.
