The present invention aims to provide a system that allows multiple users operating a PDA (Personal Digital Assistant), receiving information from a server via a cellular phone, to access the Internet or the World Wide Web (WWW), view and interact with these images remotely on a display screen. The invention relates to the priority in which packets or blocks of information are transferred to and displayed on the screen of the PDA device. The invention further relates to various methods to reduce the amount of data sent to the PDA for back pages or previously viewed web pages, stored in the cache memory of the PDA and also mirrored on the server's memory. Various algorithms may be used by the server to determine what information is to be removed from the PDA's cache memory, as it approaches its full capacity.
