VDU

VDU Abbrev. for visual display unit. A device that consists of a display, keyboard, and computer connection. Many VDUs also provide a selection of display attributes that can be used to emphasize or differentiate items of information, for example:

(a) blink or flash – in which the items are intermittently displayed at a rate that can be readily perceived;

(b) brilliance – in which a noticeable difference in illumination is applied in a steady state;

(c) reverse video – in which the character is displayed in the opposite contrast to the surrounding information, e.g. by substituting black for white and vice versa;

(d) underline – in which a line, usually displayed at the same brilliance or blink rate as the associated character, is drawn beneath the character;

(e) color – the color of the item and its background may be controlled individually.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
