I do not know that there is an exact definition of globalization, but I can tell you what it is.
Globalization is the process by which countries come to do more trade with one another. In other words, we say globalization is happening when there gets to be more trade and more different kinds of trade between more countries.
Right now, there is a lot of globalization going on. Part of this is due to easy communication, like the internet, that allow companies in different countries to stay in contact with each other quite easily.
Two good examples of globalization are
- How so many of the things we use are made in China and exported to the US.
- How many jobs like customer service are done in India -- they communicate with us through telephone and internet connections.
