Globalization (or globalisation) in its literal sense is the process of globalizing, transformation of some things or phenomena into global ones. It can be escribed as a process by which the people of the world are unified into a single society and function together. This process is a combination of economic, technological, sociocultural and political forces. Globalization is very often used to refer to economic globalization, that is integration of national economies into the international economy through trade, foreign direct investment, capital flows, migration, and the spread of technology.
