Thin Client Terminals
A thin client terminal acts as a device is designed to provide
just those functions which are useful for user-interface programs.
Often such devices do not include hard disk drives, which may become
corrupted by the installation of misbehaved or incompatible software,
but instead, in the interests of low maintenance cost and increased
mean-time between failures (MTBF) the thin client device will use
read-only storage such as a CD-ROM or flash memory.
"Thin client" has also been used as a marketing term
for computer appliances designed to run thin client software. An
X terminal, Wyse Winterm, Clearcube or Web kiosk might be considered
thin client terminals in this sense.

"Thin
client" has also been used as a marketing term for computer
appliances designed to run thin client software. An X terminal,
Wyse Winterm, Clearcube or Web kiosk might be considered thin
clients in this sense.
An X terminal is a piece of dedicated hardware running an
X server as a thin client. This architecture became popular
for building inexpensive terminal parks for many users to
simultaneously use the same large server. This use very much
aligns with the original intention of the MIT project.

X terminals
explore the network (the local broadcast domain) using the
X Display Manager Control Protocol to generate a list of available
hosts that they can run clients from. The initial host needs
to be running an X display manager.
Dedicated (hardware) X terminals are no longer common; the
same functionality is typically provided at a lower cost with
either a user's Microsoft Windows PC running an X server program
or a low-end PC running Linux.

A word about dumb terminals:
A dumb terminal in computing consists of a computer screen and keyboard,
but practically no processing ability. They allow a user to carry
out work on a remote server, minicomputer or mainframe. They have
largely been superseded by personal computers.
Dumb terminals, sometimes dubbed glass teletypes, display text
on a screen, usually in monochrome, and allow the user to send commands
to the server computer to input or display data, or to perform some
action. They include limited processing power to enable them to
issue simple commands ('escape sequences') for clearing the screen
and positioning the cursor. Some later terminals included a limited
graphic display capability.
In the 1970s and early 1980s, a number of companies manufactured
dumb terminals. The most common were DEC, Wyse, Televideo, IBM,
Lear-Siegler and Heath.
Today, most telnet clients provide emulation of the most common
dumb terminal -- the DEC VT100.
Smart terminals whioch would include thin client terminal provide
additional resources to perform local editing and simple processing.
Basically, such smart terminals (often referred to as network computers
or simply NCs) are low-cost PC platforms with no external storage
like hard disks or CD-ROM drives booting from a server in the network.
