In the fact, the other problem is all computational is to access web contents and applications anytime, overheads are shifted to the client in the system. anywhere, and on any devices. Most of Internet services and In server-based adaptation, the functionalities of the most of web contents have been designed for desktop web server are enhanced on content adaptation. computers, and often contain rich medias, such as images, Transmission time is reduced because the contents have audios, and videos. However, some devices are different from network connectivity, processing power, storage already been adapted. Traditionally, some variants of the capacity, display size, and formative handling capability. In same content are stored on the server, and it selects to many cases, the content designed for computers is not match the client identification. A common way for suitable for new (and often mobile) devices. Therefore, providing content to different devices is to store the content adaptation is needed in order to optimize the service content in Extensible Markup Language (XML) and uses for different devices and access methods.
