error control

error control (error management, error handling) The employment, in a computer system or in a communication system, of error-detecting and/or error-correcting codes with the intention of removing the effects of error and/or recording the prevalence of error in the system. The effects of errors may be removed by correcting them in all but a negligible proportion of cases. Error control aims to cope with errors owing to noise or to equipment malfunction – in which case it overlaps with fault tolerance (see fault-tolerant system) – but not usually with the effects of errors in the design of hardware or software. An important aspect is the prevention of mistakes by users. Checking of data by software as it is entered is an essential feature of the design of reliable application programs.

Error control is expensive: the balance between the cost and the benefit (measured by the degree of protection) has to be weighed within the technological and financial context of the system being designed. See also error recovery.

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.
