|
|
</H2>
|
|
|
|
<P>An X terminal is a device which communicates and displays over a network
|
|
using a distributed network window system known as X. Typically, the
|
|
terminal's X software, known as the X server, is retrieved from the network
|
|
at boot time. Programs other then the X server software (X client programs)
|
|
are not run locally on the X terminal (with some exceptions); instead, the
|
|
X terminal displays programs running on other hosts on the network. The X
|
|
terminal, therefore, is a type of network computer which uses the X
|
|
protocol to access network resources.

|

</H2>
|
|
|
|
<P> The NCD X terminal (model Xncd19r was used in preparation of this
|
|
document) has an RJ-45 (twisted pair) connector for use with 10baseT
|
|
Ethernet. A hub is required to link more than two Ethernet devices using
|
|
twisted pair. If the X terminal and its host are the only devices in the
|
|
network, they may be connected with a 'null' cable which is described in
|
|
the Linux Ethernet HOWTO document.
|
|
<P>

|
<H2><A NAME="ss3.3">3.3 NCD X server software</A>
|
|
</H2>
|
|
|
|
<P>The terminal's X server software file is available from the manufacturer
|
|
and presumably is provided with the terminal upon initial purchase. This
|
|
file will reside on the boot host where it can be accessed by the X
|
|
terminal when it boots. This file is specific to the terminal type but
|
|
independent of boot host. The terminal can boot from any host which
|
|
supports the boot communication protocol (explained later). In addition to
|
|
X server, the X software may also include applications, like a window
|
|
manager, which can run locally on the X terminal itself.
