object-oriented architecture

object-oriented architecture An architecture in which everything (processes, files, I/O operations, etc.) is represented as an object. Objects are data structures in memory that may be manipulated by the total system (hardware and software); they provide a high-level description that allows for a high-level user interface. Objects have descriptors that are referred to variously as names, pointers, and labels. These descriptors also provide information as to the type of object and a description of capabilities that apply to the particular object. Object-oriented architecture systems can thus be considered as an extension or generalization of capability architecture systems, and have the same ability to provide a basis for protection and computer security.

Examples of object-oriented architecture systems are the IBM System 38, the Carnegie-Mellon experimental C.mmp/Hydra, and the Intel iAPX 432.

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.
