To clear even more confusion
Localization (or localization for non-American people), L10n for short: the process of adapting a program to a specific location. It consists of translation of resources, adaptation of the user interface (if necessary), etc.
Internationalization, i18n for short: the process of adapting a program to support localization, regional characters, formats, etc. etc., but, most importantly, the process that allows the program to work correctly regardless of the current settings of the language standard and OS language version.
Globalization, g11n for short: consist of both i18n and L10n.
