The process of making an application ready for global usage is globalization or G11N (for the 11 letters between the G and the N in globalization). Basically globalization consists of two steps, internationalization or I18N (for the 18 letters between the I and N in internationalization) and localization or L11N (for the 10 letters between L and N in localizatio—if you're sensing a pattern here, yes there is, people working in this field are particularly fond of numeronyms). The atomic units for globalization are locales. Locales are the most important piece of G11N.
Locales are languages and calendars; date, number, and currency
