BeOSX Window System The PostScriptbased NeWS (Network extensible Window System) was developed by Sun Microsystems. For several years SunOS included a window system bining NeWS and the X Window System. Although NeWS was considered technically elegant by some mentators, Sun eventually dropped the product. Unlike X, NeWS was always proprietary software. The X Window System The standard windowing system in the Unix world, developed in the early 1980s, is the X Window System, or X. X was developed at MIT as Project Athena. Its original purpose was to allow users of the newly emerging graphic terminals to access remote graphics workstations, without regard to the workstation’s operating system or the hardware. Due largely to the availability of the source code used to write X, it has bee the standard layer for management of graphical and input/output devices and for the building of both local and remote graphical interfaces on virtually all systems, including UNIX, the BSD operating systems and the GNU/Linux distributions. X allows a graphical terminal user to make use of remote resources on the work as if they were all located locally to the user by running a single module of software called the X server. The software running on the remote workstation is called the client application. X’s work transparency protocols allow the display and input portions of any application to be separated from the remainder of the application and ’served up’ to any of a large number of remote users. In the early days of X Window development Sun Microsystems and ATamp。 T attempted to push for a GUI standard called OpenLook in petition with Motif. OpenLook was a welldesigned standard developed from scratch while MOTIF was a collective effort that fell into place. Many who worked on OpenLook at the time appreciate its design coherence. Motif prevailed the ’religious’ war and became the bases for CDE (Common Desktop Environment). Both X and Open Motif are available today as free software. In the late 1990s, there was significant growth in the Unix world, especially among the free software munity. New graphical desktop movements grew up around GNU/Linux and similar operating systems, based on the X. A new emphasis on providing an integrated and uniform interface to the user brought about new desktop environments, KDE and GNOME. See also:  Apple v.
