X Window System

operating system, graphics A specification for

device-independent windowing operations on bitmap display

devices, developed initially by MIT's Project Athena and

now a de facto standard supported by the X Consortium. X

was named after an earlier window system called "W". It is a

window system called "X", not a system called "X Windows".

X uses a client-server protocol, the X protocol. The

server is the computer or X terminal with the screen,

keyboard, mouse and server program and the clients are

application programs. Clients may run on the same computer

as the server or on a different computer, communicating over

Ethernet via TCP/IP protocols. This is confusing because

X clients often run on what people usually think of as their

server (e.g. a file server) but in X, it is the screen and

keyboard etc. which is being "served out" to the applications.

X is used on many Unix systems. It has also been described

as over-sized, over-featured, over-engineered and incredibly

over-complicated. X11R6 (version 11, release 6) was released

in May 1994.
