Crossing the boundary: analogue universe, digital worlds

This course, Crossing the boundary: analogue universe, digital worlds, explores the way in which information, in the form of text, still and moving images, and sound can cross the boundary from the analogue universe into a digital world.

Course learning outcomes

After studying this course, you should be able to:

• Give examples of quantities that are intrinsically analogue, and quantities that are intrinsically discrete/digital
• Define the terms ‘bit’, ‘byte’ and ‘word’
• Outline how visual information, such as pictures, diagrams and moving images can be expressed numerically inside a computer
• Describe how sounds such as speech and music can be represented inside a computer in terms of numbers.
