text mode

text mode (character mode) A way of using a computer display such that the basic unit is the character cell – the space taken up by a single character. The only images that can be displayed are those that can be built from character-sized blocks; surprisingly complex images can however be built in text mode. A display device can be operated in a number of different text modes. The coarsest is probably the 40 characters by 24 lines used in some teletext systems, while some text modes have 132 characters per line. Each character has attributes such as color, boldface type, blink, underline, or reverse video. Compare graphics mode.

Learn more about citation styles

Citation styles 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, cannot guarantee each citation it generates. Therefore, it’s best to use 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:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most 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.
