11. Multimedia Types
The main multimedia data types we will meet on this course are:
- Images, video, audio, text, and animation
We will also discuss how we capture this data...
- capture = get it into the computer
...and render this data
- render = display or play the information
We will also find out about the hardware devices that are used to capture and render the data

12. Multimedia Applications
Multimedia applications can be linear or interactive
Linear multimedia plays from some start position to some end position with little or no intervention
- Just like this lecture
Interactive multimedia allows the viewer to jump around the material by interacting with it
