by the use of a file format known as Flash.
Flash has become a ubiquitous standard on the web for delivering animations.
Flash has the ability to deliver sophisticated animations, interactivity
and sound within one file.
Flash files are scalable. This
means that the same file can be resized (e.g. to fill a different proportion

Flash files are a streaming media format.
