Abstract: A network connection system for sharing data among networks using a shared storage to enable easy mail transception, file transception, and use of clipboards, including a first terminal connected to a first network; a first network connection server between a shared storage and the first terminal to control or transceive data; a second terminal connected to a second network; a second network connection server between the shared storage and the second terminal to control or transceive data; having a single storage space shared by the network connection servers. Using separate portable storage media is eliminated, and a clipboard may be used. In addition, mail may be converted and transceived among the networks to reduce security risks, and files may be transceived among networks even when multiple terminals are accessed, eliminating loads on a server and improving quality of shared storage.

Abstract: The present invention relates to a network connection system for sharing data among independent networks, and more particularly, to a network connection system for sharing data among independent networks, which enables networks to share data using a shared storage in an independent environment to enable easy mail transception, file transception, and use of clipboards among independent networks.
