Which term best describes the cultural, economic, and social communication and connection between various groups throughout the world?

The term that best describes the cultural, economic, and social communication and connection between various groups throughout the world is "globalization".

Explanation:

Globalization is an ongoing process of global economic, political and cultural integration, with the central feature being a global division of labor, spreading production lines around the world that are driven by information and communication technology and by international trade. Globalization is made possible by developments in the field of transport and telecommunications. It is further characterized by far-reaching scaling-up, the emergence of global capitalism and the spread of a consumer culture.

With regionalization, globalization results in internationalization, in which relationships are established over ever greater distances and thus extend beyond national borders. As a result, national governments are bound by their agreements to international agreements and developments and have less control over the national economy.
