Software Localization:

The Localization Industry Standards Association (LISA) defines localization services as "the process of modifying products or services to account for differences in distinct markets". Software localization is thus much more than translating user interfaces from one language to another. It is about adapting all cultural content and technical issues to a specific audience in a given location.
localization means ensuring that your software "speaks" the language of your customers. In a world of globalization, localization can make the difference between success and failure in your target markets. However, as the business environment becomes increasingly competitive, the challenge of adapting software, documentation, online help, Web pages and manuals to conform to the cultural, linguistic and regulatory needs of each customer becomes formidable. Localization has effectively become the cost of doing business in the global market.

Internationalization

Is the process of translating software UI (user interfaces) from one language to another and altering it to suit foreign clients and their culture norms. this in not just about translating languages, but adapting from one culture to another.
Globalization makes your software ready for the global market. Localization includes the program itself and any online or printed documentation. As the competition among the many software developers increases, software companies are increasingly challenged to localize its software, documents, web pages, and manuals to each customer's different cultural and language needs. In addition, there are increasing regulatory, cultural and compliance pressures that companies need to deal with. a well executed globalizations process can aid in opening new markets and retaining current clients.
Localization is not limited to translating English into other languages (as most software continues to be developed in the U.S.) but also includes every language from French, Spanish, Chinese, Arabic, etc.
