What Does X Terminal Mean?
An X terminal is an input terminal with a display, keyboard, mouse and touch pad that uses X server software to render images. Used as an open-source windowing system known as the X Window System, the X terminal does not perform application processing - this is handled by the network server.
X allows applications to run on a network server but be displayed on the X terminal or desktop machine. During the 1980s-1990s, this industry stride was significant because servers were much more powerful than personal computers. X and the X terminal were therefore the forerunners of modern thin clients (network computers) and network server operating systems.
An X terminal is also known as a diskless computer.
