11. network based approach is that if the network shuts down the application cannot be accessed Of course if the network shuts down a Java application in an MFP is not in a position to send images over the network and the printer will not be available for printing just for copying Another problem based on the network is that if a large number of MFPs interact with an application on a server that network could create a bottleneck However in most applications two or more servers may be deployed to adequately serve the expected demands In addition the image compression capability helps reducing network traffic The software on the server that hosts Web pages is then used to put forward information to the user on the MFP Control Panel The data that the user through the control panel goes communicate to the server and at the same time can be used on the communication with other applications It is easier to develop screens and intuitive control panel with a browser As the applications are not within the MFP this reduces the need for processing power or memory on the device and but increases network dependence Web 2 0 is a term describing the trend in the use of World Wide Web technology and web design that aims to enhance creativity information sharing and most notably collaboration among users 19 SOA is a computer system s architectural style for creating and using business processes packaged as services throughout their lif
