What is a rich internet application?
The rich Internet application performs and acts as a locally installed desktop program, except that it is used via the Internet. Without Internet access, there is no way to open the computer and use rich Internet applications. Unlike the traditional program, which must be installed via a hard disk and added to the desktop, this application does not work any room and does not pass through the installation process. At the same time, some applications can only work on some Internet browsers, or may have to be programming languages or other additional programs installed to open these applications. This means that users, outside the Internet to use the program, should not notice any differences between the functionality of rich Internet programs and desktop programs. There are other similar programs known as the programs of the thin client that are accessible from the server; It is similar to a rich internet application, but because it is involvedEN Server, is classified differently.
One of the biggest differences between the rich internet application and the desktop applications is access to them. The desktop application is running from the desktop while the Internet application is accessible via the Internet. This means that the computer must have continuous access to the Internet, or the program will not start or stop working when the connection is lost. Although it may be a disadvantage for people who have poor Internet power, it usually makes it easier for people with good Internet connection programs.
When someone buys or receives software, they must usually be installed. The installation is rarely long and some programs only occupy the nominal bath of a hard discussion, while others occupy more space. In most cases, a rich Internet application is not installed; Maybe it will be necessary to download, but it is unusual.
At the same time it is necessary toInstall other programs. Some rich Internet applications cannot work properly without any backup, and these additional programs provide this. Unlike desktop applications where each program is individually installed, one additional program should be able to support many Internet applications. There is also a chance that a rich Internet application will only work in a certain browser or that some features can work best in a certain browsing environment.
