Adobe Flash Player :-
The Adobe
Flash Player is freeware software for
viewing multimedia,
executing rich Internet applications, and streaming video
and audio, content created on the Adobe Flash platform.
Flash Player can run from a web browser
or on supported mobile devices, but there also
exist versions running directly on an operating system intended
both for regular users and content developers, denoted with the Projector
and Debugger name suffixes, respectively. Flash
Player runs SWF files
that can be created by the Adobe Flash Professional authoring
tool, by Adobe Flex or
by a number of other Macromedia and
third party tools. Flash Player was created by Macromedia and
now developed and distributed by Adobe Systems after
its acquisition.
