Flash player is a widely distributed proprietary multimedia and application player created by Macromedia and now developed and distributed by Adobeafter its acquisition. Flash Player runs SWF files that can be created by the Adobe Flash authoring tool, by Adobe Flex or by 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. Since its inception, ActionScript has matured from a script syntax without variables to one that supports object-oriented code, and may now be compared in capability to JavaScript (another ECMAScript-based scripting language).
