ABSTRACT:
In a document information system and a method for realizing such a system, document data are transferred and displayed at a high speed. In response to an operation made from a terminal apparatus, the document data which have been stored via communication apparatus into a data storage apparatus are read out, and the read document data are temporarily stored before being transmitted by employing the communication apparatus. In the terminal apparatus, the received document data are temporarily stored as display data, and additionally the display data are swapped to a secondary storage device in such a case that a total amount of the temporarily stored data exceeds a predetermined capacity. Then, the display data may be transferred from either the terminal apparatus, or the secondary storage device to a display buffer and then may be displayed in a unit of representation.
