Network transparency
Network transparency in its most general sense refers to the ability of a protocol to transmit data over the network in a manner which is transparent (invisible) to those using the applications that are using the protocol.
The term is often partially correctly applied in the context of the X Window System, which is able to transmit graphical data over the network and integrate it seamlessly with applications running and displaying locally; however, certain extensions of the X Window System are not capable of working over the network.
