An X server runs on the X terminal, connecting to a central computer running an X display manager. In this example, client programs (Template:Mono and Template:Mono) are running on the same computer.

In computing, an X terminal is a display/input terminal for X Window System client applications. X terminals enjoyed a period of popularity in the early 1990s when they offered a lower total cost of ownership alternative to a full Unix workstation.Template:Citation needed

An X terminal runs an 'X server'. In X, the usage of "client" and "server" is from the viewpoint of the programs: the X server supplies a screen, keyboard, mouse and touchscreen to client applications. This connects to an X display manager (introduced in X11R3) running on a central machine, using XDMCP (X Display Manager Control Protocol, introduced in X11R4).<ref>Template:Citation.</ref>Template:Page needed

Thin clients have somewhat supplanted X terminals in that they are equipped with added flash memory and software for communication with remote desktop protocols.

Vendors

In the early 1990s, several vendors introduced X terminals including HP, DEC (including the VT1000 series), IBM, Samsung, NCD, Gipsi,<ref>Template:Citation.</ref> Tektronix,<ref>Template:Cite journal</ref> and Visual Technology.<ref name=techmonitor>Template:Cite journal</ref>
