• With vector graphics - very small file size, Flash is extremely convenient for data transmission over the Internet and this is also the biggest advantage of this multimedia creation program.

Cons of Flash

• Over the past few years, Flash has been constantly exposed (or has) serious security holes. Therefore, websites and products that were created from this tool are at great risk of being attacked by hackers.
• It is for this reason that a large number of giants such as Facebook , Youtube , Firefox ... all simultaneously "boycott" Flash and call Adobe to "kill" this program.
• According to technology experts, leading security companies in the world, Flash is now obsolete and no longer appropriate, nor can it be advanced and secure using HTML5 or WebGL standards .

Flash file format

One noticeable point is that Flash files almost always have the .swf extension (Shockwave Flash) and can be displayed by Web browsers such as ( Chrome , Mozilla Firefox, Internet Explorer , Coc Coc ... ) or the Flash Player application.

Flash files are also often animations, advertisements or other decorative elements of a Web page. Recently Flash has also been used to create richer Internet applications. If you have to compare the dimensions and features, then at the same size, a Flash file can contain more information than an image file in GIF or JPEG format.

Practical application of Flash

According to many, " Macromedia Flash " should be used to invoke the program to create Flash files. The " Flash Player " should be reserved only for applications that execute or display those Flash files. However, since both terms have the word "Flash", by default, it is used to call and talk about both programs. Specifically:

Website

• Flash can be a whole website or it can be just a part of that website. We can see the easiest is the flash video player of the world famous video sharing site - Youtube. Although only encapsulated within a player to watch videos, what this site brings is not small and we all know.
• Banners, advertisements, intros, are so common and can be found on many websites (gamevui).

Animation

Conclude:

Science and technology are constantly changing day by day, "development spiral" will produce new things, deny and "overshadow" the old. Therefore, "regress Flash" is an inevitable inevitable.

However, it is also undeniable that Flash has done very well, perfect the role of a "predecessor". It is a very important historical premise, while HTML5 and WebGL are still just "ideas", definitions being tested or lying on a desk.
