Different meanings of trading

If you want to know something more about the meaning of trading have a look here. I'm fond of economics and everything related to that field. I've gathered some information about the different uses of that word.
First of all, trade is the voluntary exchange of goods and services and market is the mechanism that allows trade. Trade is believed to have taken place throughout much of recorded human history. There is evidence of the exchange during the stone age. Materials used for creating jewelry were traded with Egypt since 3000 BC. The Roman empire produced a stable and secure transportation network that enabled the shipment of trade goods without fear of piracy.
The original form of trade was barter, the direct exchange of goods and services. Later instead of the barter there were precious metals, bill and paper money. Modern traders instead generally negotiate through money. The invention of money greatly simplified and promoted trade.

The word trade also refers to international trade, which is the exchange of goods and services across national borders. While international trade has been present throughout much of history, its economic, social, and political importance have increased in recent centuries. In fact, it is probably the increasing prevalence of international trade that is usually meant by the term "globalization".
International trade is usually regulated by governmental quotas and restrictions, and often taxed by tariffs. Tariffs are usually on imports, but sometimes countries may impose export tariffs. All of these are called trade barriers. If a government removes all of them, a condition of free trade exists.

The fair trade movement promotes the use of labour, environmental and social standards for the production of commodities. Standards may be voluntarily adhered to by importing firms, or enforced by governments through a combination of employment and commercial law.
