DECwindows Motif

Summary

Product Overview A GUI to an OpenVMS system.The DECwindows Motif software follows a client/server processing model, where the server is a single-shared process that performs operations at the request of many client processes.In most client/server relationships, the client system is located on the desktop, while the server system resides across the network. With DECwindows Motif, as in all X Window System environments, the server system resides on the desktop and displays graphics onscreen.The client is a process, such as a desktop application or X Window System utility, that issues X protocol requests. For example, in the DECwindows Motif environment, desktop applications (such as DECterm) and X Window System utilities (such as xlsfonts) are the clients that interact with the X display server. The client controls what appears on the display server system and generates the graphic interface with which the user interacts.In the DECwindows architecture, as with most client/server processing models, the client and display server may reside on separate systems. These systems are connected to each other by a network transport that is essentially transparent to the user. DECwindows Motif supports the following transport mechanisms:Local (shared memory)Local Area Transport (LAT)DECnetTCP/IP (IPv4 and IPv6)
