词条 | X terminal |
释义 |
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. 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).[1]{{Page needed |date=October 2015}} Thin clients have somewhat supplanted X terminals in that they are equipped with added flash memory and software for communication with remote desktop protocols. VendorsIn the early 1990s, several vendors introduced X terminals including Network Computing Devices (NCD), Gipsi, Hewlett Packard (HP), Digital Equipment Corporation (DEC, later absorbed by HP), IBM, Samsung[2] and Tektronix.[3] References1. ^{{Citation | first1 = Linda | last1 = Mui | first2 = Eric | last2 = Pearce | title = X Window System | volume = 8: X Window System Administrator's Guide for X11 Release 4 and Release 5 | edition = 3rd | publisher = O'Reilly & Associates | date = July 1993 | type = softcover | ISBN = 0-937175-83-8}}. {{XWinSys}}{{compu-hardware-stub}}2. ^{{Citation | url = https://books.google.com/books?id=nzsEAAAAMBAJ&pg=PT39 | title = InfoWorld | date = 28 May 1990}}. 3. ^{{cite journal |last=Corcoran |first=Cate |year=1992 |title= Study shows 115 percent increase in X terminal sales for 1991 |journal=InfoWorld |volume=14 |issue=3 |pages=26 |url= https://books.google.com/books?id=9T0EAAAAMBAJ&pg=PA26&dq=x-terminal&cd=3#v=onepage&q=&f=false |quote= Network Computing Devices dominated the market...
