How does the computer's peculiar binary world of digital entities differ from our analogue world of colour, sound, taste and touch? This free 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.
