Nomenclature

The abutment of assorted languages by computer systems can be advised a continuum amid localization ("L10n"), through multilingualization (or "m17n"), to internationalization ("i18n").

A localized arrangement has been acclimatized or adapted for use in a accurate area (other than the one it was originally developed for), including the accent of the user interface (UI), input, and display, and appearance such as time/date affectation and currency. Each instance of the arrangement alone supports a individual locale, and there is no absolute abutment for languages that are not allotment of that area (although the appearance set may accordingly be accessible for added languages).

Multilingualized software supports assorted languages for affectation and input, but has a individual UI accent which cannot be afflicted afterwards accession of the software. Multi-locale abutment for added appearance like date, time, number, and bill formats varies as the arrangement tends appear abounding internationalization. At present, a lot of multi-lingual software relies for these appearance on the host operating arrangement (e.g., Microsoft Windows or Mac OS X) of the apparatus on which the software runs, and may appropriately be able to abutment appearance sets for altered languages aural the aforementioned document. In general, a multilingualized arrangement is advised for use in one specific locale, but is able of administration multilingual agreeable as data.

An internationalized arrangement is able for use in a ambit of "locales" (or by users of assorted languages), by acceptance the co-existence of several languages and appearance sets for input, display, and UI. In particular, a arrangement may not be advised internationalized in the fullest faculty unless the UI accent is selectable by the user at runtime. Abounding internationalization may extend above abutment for assorted languages and orthography to acquiescence with jurisdiction-specific legislation (in account of copyright, for instance) and added non-linguistic conventions.

The acumen arises because it is decidedly added difficult to actualize a multi-lingual UI than artlessly to abutment the appearance sets and keyboards bare to accurate assorted languages. To internationalize a UI, every argument cord active in alternation have to be translated into all accurate languages; again all achievement of accurate strings, and accurate parsing of ascribe in UI cipher have to be replaced by hooks to i18n libraries.

It should be acclaimed that "internationalized" does not necessarily beggarly that a arrangement can be acclimated actually anywhere, back accompanying abutment for all accessible locales is both about about absurd and commercially actual harder to justify. In abounding cases an internationalized arrangement includes abounding abutment alone for the a lot of announced languages, additional any others of accurate appliance to the application.
