Adobe Flash, or simply Flash, can refer to both the Flash Professional multimedia authoring program and the Flash Player plug-in. Written and distributed by Adobe, it 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. In , the authoring environment was rebranded as Adobe Animate. 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.
The Flash Player was originally designed to display 2-dimensional vector animation, but has since become suitable for creating rich Internet applications and streaming video and audio. It uses vector graphics to minimize file size and create files that save bandwidth and loading time. Flash is a common format for games, animations, and GUIs embedded into web pages.
The Flash Player was built into some browsers and was available as a plug-in for recent versions of other browsers such as Firefox , Opera , Safari and Internet Explorer on selected platforms. Each version of the plug-in was completely backwards-compatible. However, it was also criticized for its security issues and support was phased out of major browsers by the end of On September 15, Adobe by way of Lee Brimelow 's "The Flash Blog" announced the release of a public beta preview, native bit Flash Player code-named "Square" for all major platforms and browsers.
Previously no x editions of the Flash player were available for any platform [3] , due to the complexity of porting the xspecific garbage collector and just-in-time compilation engine [4] to native bit platform specific code. Adobe engineers in had already stated that bit editions for all supported platforms, including Linux, were in development [5]. Adobe however, had been developing a x64 edition of the Flash Player since While the new beta version on labs support bit natively, it's still a long way from finished, to that end, Adobe as of yet have not stated if and when a stable, final release will be given.
Although SWF has recently become an open format again, Adobe has not been willing to make complete source code available for free software development. It includes the specification for the ActionScript byte code format. This project is jointly managed by Mozilla and Adobe. The full specification of the SWF format is available without restriction by Adobe. The principal alternative free software player, Gnash , is quite incomplete at this time, however since SWF is now an open format, it should have a much higher quality going forward as developers implement the official SWF specifications.
Flash Player is an application that, while running on a computer that is connected to the internet , is designed to contemporaneously interact with websites containing Flash content that are being visited online. As such, under certain configurations the application has the potential to silently compromise its users' internet privacy , and do so without their knowledge. By default, Flash Player is configured to permit small, otherwise invisible "tracking" files, known as Persistent Identification Elements PIE [7] or Local Shared Object files, to be stored on the hard drive of a user's computer.
Sent in the background over the internet from websites to which a user is connected, these files work much the way " cookies " do with internet browsers. When stored on a user's computer, PIE. Instead access to the various settings panels necessary to manage the application's "Privacy," "Storage", "Security", and "Notifications" settings can be achieved through a web-based Settings Manager page located on the "support" section of the Adobe. Whilst the Flash Control Panel Settings in theory allow users to protect their privacy it should be remembered that suitably crafted Visual Basic Script or similar code can overwrite any user defined settings before the Flash Player plug-in is called by a webpage.
In addition to cookies , many banks and other financial institutions also routinely install Persistent Identification Elements using Flash Player on users' hard drives when they establish and access their accounts, as do other interactive sites such as YouTube.
However, the Flash platform has since been deprecated by Adobe and support was phased out of major browsers by the end of FutureWave pitched the product to Adobe Systems , but an agreement was not reached and Adobe initially promoted rival specifications to Flash. FutureSplash Animator then became Macromedia Flash. Flash MX was split into basic and professional versions. Macromedia was acquired by Adobe Systems in December End-of-life image displayed by deprecated Flash Player plug-ins after January 12, In July , Adobe announced that it would phase out support for Flash Player by the end of The latest Flash plug-ins began blocking playback of content on January 12, Macromedia Wiki Explore.
