frame relay

frame relay A form of network transmission in which packets from different lower-speed sources are encapsulated together to form a very large frame, up to several hundred bytes in length, which is then transported as a unit on a single higher-speed bearer. The frame will usually have a fixed length, and more or less fixed internal structure. The fixed size and relatively simple internal structure of the frames means that the switching activity can be implemented with a considerable degree of hardware assistance, while the larger frame size reduces the ratio of overheads to useful payload. In particular it is possible to allow packets to enter or leave the frame relay system using an assembly of standardized products.

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.
