In November 07,2006  Khun Vichai Wattanawornwong who work in a huge company , IBM , was lectured about GILT ( Globalization, Internationalization, Localization and Translation ) that since 1300s to now, world were divided in 4 part time that depend on environment to make it good society among country around the world such as economics, political, health, technology or anything else. And most one of them among a long time is technology and trading that show you since translation in 1300s and this is a beginning of high-technology now. In translation, when trading we have a piece of paper to make trading easily although buyer or seller were used another language and can use this many times and keep it like database to know what you buy or sell. And parts of problem with the source text are 1. Changes made to the text during the translation process 2. Illegible or difficult-to-read text 3.Misspelled or misprinted text 4. Incomplete text or etc. Any type of written text can be a candidate for translation; however, the translation industry is often categorized by a number of areas of specialization. Each specialization has its own challenges and difficulties and this bring into localization In software development, after a product has been internationalized, "localization" refers to the process of making it ready for a specific market.  Software localization is a process of translating software user interfaces from one language to another and adapting it to suit a foreign culture. This process is labor-intensive and often requires significant efforts from development teams. There are tools that can simplify the localization process. A lot of these projects get outsourced to specialized companies to cut costs. In localization, it can also refer to adapting software from one culture to another. During localization, some references to history or culture are replaced with an equivalent native reference which ideally does not change the meaning of the statement.

In internationalization, that is often abbreviated as I18N (or i18n or I18n) where the number 18 refers to the number of letters omitted (internationalization) 1. Localization is often abbreviated L10n or l10n in the same manner. (The most common forms are i18n and L10n, respectively. These forms won out because many fonts do not readily distinguish uppercase "I" and lowercase "l", but lowercase "i" and uppercase "L" are always clear.) These abbreviations also avoid picking one spelling (internationalization vs. internationalization, etc.) over the other. Both notions are sometimes collectively termed globalization (g11n).Internationalization is sometimes used interchangeably with globalization to refer to economic and cultural effects of an increasingly interconnected world.
