FlashAdobe Flash Player allows quick installation. The use of vectorial graphics (such as PostScript, SVG and PDF) – especially when they are combined with ActionScript code for animation – allows Flash files to be small files that use less bandwidth than bitmaps or videos. On several points, Flash is a very interesting solution to transmit multiple content. If the content is simply a format (such as text , video or audio), other alternatives may provide better results. However, this depends on the type of application or animation created. Flash animation can take more CPU. According to Macromedia, Adobe Flash (plug-in or ActiveX for Internet Explorer on Windows) drive is currently present in 97% of browsers worldwide, 90% possess the latest version, according to a study by NPD. Other sources, such WebHits, argue below 70% rate in 2005.

Flash Player 8 offers two video codecs VP6 of On2 Technologies and Sorenson Spark, and startup acceleration JPEG, Progressive JPEG, PNG, and GIF. In its next version, flash player should be able to use the compiler JIT (“just- in-time”) for the ActionScript engine. Flash is very common on computers. According to NPD, 98% of U.S. Internet users have the Flash player installed, with 45% – 56% having the latest version. The reader is for a very large number of systems and devices. The contents can be read without problems on Microsoft Windows, Mac OS and Linux i386 (Macromedia has created or licensed drives for the following systems: Windows, Mac OS 9/X, Solaris, HP- UX, Pocket PC, OS/2, QNX, Symbian, Palm OS, BeOS, and IRIX). By default, Macromedia Flash Lite allows compatibility with other systems.

Flash Player 8 has never been released for Linux. This decision was challenged in the Linux community because some people felt that Adobe abandoned the Linux market. Adobe has announced that they would dismiss this version to focus on Version 9, launched shortly after the Windows and Mac OS X versions. Paradoxically, websites insist on using the most recent versions, Adobe claims that their flash drives are “Linux compatible”. The release of version 9 has helped to improve this situation. This plug-in exists on many platforms (PC (Windows, Mac OS or GNU/Linux), Pocket Pc, Psp, Mobile … ). Unix systems support versions 9 and 10 but not 8 of the drive and only work on certain versions of Linux, ALSA sound drivers, no OSS support, or esd). Lack of support for older Linux can be circumvented by using Wine.

Adobe offers its users which accept the license to use the opportunity to develop specific programs that can be exported to Flash format. The license prohibits use of the specifications to create programs for copying Flash files. Flash technology is increasingly used for advertising content, sometimes unwanted. It was created for Mozilla and its derivatives extensions such as FlashBlock to block Flash advertising content, loading unwanted introductory pages and queries Flash installation.

Flash Player is a proprietary plugin (or an ActiveX) whose sources are not available. Other projects for flash players exist as GPLFlash and swfdec, in a variable stage of completion. Finally, given the wide distribution of the flash, the development of a consistent reading program has been on the list of priorities of the FSF. The project is called Gnash.
