	A '''video terminal''' (sometimes called '''video display terminal''', or '''VDT'' for short) was a [[terminal]] on which the characters being output were 'painted' on a [[cathode ray tube\|CRT]] via a purely [[electronic]] process. It was thus roughly the same functionality as the earlier [[printing terminal]]s, such as [[Teletype]]s, but instead of the output being printed on paper by a mechanical system, it was displayed on the screen. Like the earlier printing terminals, they were used to allow a [[user]] to do [[input/output]] to a computer; they usually communicated with the computer via [[asynchronous serial line]].

	Very early model provided only the same motion controls as their printing predecessors - line feed, carriage return, etc. However, the ability to move the [[cursor]] to specific screen locations was soon added, which made possible a predecessor of [[WYSIWYG]], to wit, [[screen editor]]s such as [[Emacs editors\|EMACS]].
