Adobe Flash - previously called Shockwave Flash and Macromedia Flash - is a set of multimedia technologies developed and distributed by Adobe Systems and earlier by Macromedia. Since its introduction in 1996, Flash technology has become a popular method for adding animation and interactivity to web pages; Flash is commonly used to create animation, advertisements, various web page components, to integrate video into web pages, and more recently, to develop rich Internet applications.
Flash can manipulate vector and raster graphics and supports bi-directional streaming of audio and video. It contains a scripting language called ActionScript. It is available in most common web browsers and some mobile phones and other electronic devices . Several software products, systems, and devices are able to create or display Flash, including the Adobe Flash Player. The Adobe Flash Professional multimedia authoring program used to create content for the Adobe Engagement Platform, such as web applications, games and movies, and content for mobile phones and other embedded devices.
Files in the SWF format, traditionally called "Flash movies" or "Flash games", usually have a .swf file extension and may be an object of a web page, strictly "played" in a standalone Flash Player, or incorporated into a Projector, a self-executing Flash movie .Flash Video files have a .flv file extension and are used from within .swf files.
Contents.
Initially focused on animation, early versions of Flash content offered few interactivity features and thus had very limited scripting capability.
More recent versions include ActionScript, an implementation of the ECMAScript standard which therefore has the same syntax as JavaScript, but in a different programming framework with a different associated set of class libraries. ActionScript is used to create almost all of the interactivity seen in many Flash applications.Flash MX 2004 introduced ActionScript 2.0, a scripting programming language more suited to the development of Flash applications. It is often possible to save a lot of time by scripting something rather than animating it, which usually also enables a higher level of editability.
