Internationalization and localization

In computing, internationalization and localization (American) or internationalisation and localisation (Commonwealth), often abbreviated i18n and l10n respectively, are means of adapting to different languages, regional peculiarities and technical requirements of a target locale. Internationalization is the process of designing a software application so that it can be adapted to various languages and regions without engineering changes.
