Representing Data with Images and Sound: Bringing Data to Life CO209 / A06

Start date
7 Dec 20
Duration
10 Weeks

Summary

Learn how data is represented through media; audio, visual and text.

This online course 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.

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.

Outcomes

You will be able to:

  • Describe how computers represent text, images and sound in binary
  • Explain how text is represented digitally by using 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
