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.

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

Who is it for?

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)

What topics are covered?

You'll cover the following topics:

  • how computers use binary
  • Hexadecimal
  • using binary to represent colours
  • how bitmap images use binary 
  • how sound files are stored
  • compression

How will you learn?

This online, self-paced course can be completed flexibly. You can join and start this course at any time after the advertised date, and keep access for a year after booking. You can learn independently or with colleagues to directly address your individual needs.

This course will be periodically facilitated by expert Professional Development Leaders.

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
