Crossing the boundary: analogue universe, digital…
|
Learn about the differences between the digital and analogue worlds in this free course. Explore how information can be transformed from analogue to digital, and gain knowledge on quantities, terms like ‘bit’ and ‘byte’, and representation of visual and audio data in computers.
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.
