1. (filtering) A logical operation carried out on a byte, word, or field of data in order to modify or identify a part of it. A bit pattern – the same length as the item to be masked – is generated and stored in a register as a mask. By use of the appropriate operation, e.g. subtract, logical AND, logical OR, the mask can be used to suppress bits in the data, or set them to zero, etc. The process is used for purposes such as identifying the presence of high-priority bits in a status byte or resetting interrupts.
2. The use of a chemical shield, the mask, to determine the pattern of interconnects in an integrated circuit. Read-only memories (ROMs) and programmable logic arrays (PLAs) are customized for their particular applications by the masking process, unless they are field-programmable. See programmable devices.
3. A technique used in software for manipulating graphic images. An area of the image may be defined by a mark based on color, brightness, or some other parameter. The mask can then be used to allow separation of parts of the image.

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:
Modern Language Association
The Chicago Manual of Style
American Psychological Association
- 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.
