coloured book The UK academic networking community was one of the earliest to attempt to devise a complete set of open systems interconnection (OSI) standards for all aspects of its networking requirements, and to make a concerted effort to apply these to the entire community. A main thrust of the approach was the definition of protocols for each of the major networking requirements, each protocol being issued in a different colored binder. The important protocols were:

Yellow Book— defining a transport service, roughly equivalent to layer 4 of the ISO seven-layer reference model.

Green Book— defining a terminal connection protocol.

Blue Book— defining a file transfer protocol.

Grey Book— defining an electronic mail service.

Red Book— defining a job transfer and submission protocol.

Pink Book— defining a transport service to run over an ISO OSI CSMA/CD service.

Orange Book— defining a network service running over a Cambridge Ring.

Colors have been used to identify various other standards, including CD-ROM format standards.

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.
