-A '''video terminal''' was a device used to allow a [[user]] to do [[input/output]] to a computer; it usually communicated with the computer via [[asynchronous serial line]]. It was effectively roughly the same as the earlier [[printing terminal]]s such as [[Teletype]]s, but with characters being 'painted' on a [[cathode ray tube|CRT]] via a purely [[electronic]] process, instead of being printed on paper by a mechanical system.

 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]].
