Adobe Flash Player
Encyclopedia : A : AD : ADO : Adobe Flash Player
The Adobe Flash Player is a widely distributed multimedia and application player created and distributed by Macromedia (a division of Adobe Systems). Flash Player runs SWF files that can be created by the Adobe Flash authoring tool, Adobe Flex or a number of other Macromedia and third party tools.
Adobe Flash, or simply Flash, refers to both a multimedia authoring program and the Adobe Flash Player, written and distributed by Adobe, that uses vector and raster graphics, a native scripting language called ActionScript and bidirectional streaming of video and audio. Strictly speaking, Adobe Flash is the authoring environment and Flash Player is the virtual machine used to run the Flash files, but in colloquial language these have become mixed: "Flash" can mean either the authoring environment, the player, or the application files.
Flash Player has support for an embedded scripting language called ActionScript (AS), which is based on ECMAScript. As time has passed, AS has been developed from a primitive script that previously didn't support variables to a respectable programming script that can be used to make rather complex games and other applications.
The Flash Player was originally designed to display 2-dimensional vector animation, but has since evolved to support Rich Internet Applications and streaming video and audio. Today, most web browsers have Flash Player built-in, and can view Flash files on web pages as if they were images. The Flash files themselves usually consist of vector graphics, meaning that instead of rendering individual pixels, Flash Player renders lines and fills to create dynamic shapes that can be adapted in real time. Because of this, most Flash movies tend to have a cartoon-look as opposed to a realistic appearance. Most users claim this is not so much a bad thing as it makes web-based animations and simple programs/games easier to deliver to wide audiences. Because of the way Flash compresses SWF, a typical ten minute long Flash movie would have a file size (in MB) that can be counted on one hand.
