space : Trade

Trade involves buying or selling of goods in exchange for money or services or also other variety of goods. For example a person can give another person 'x' amount of currency in return for a service from another person. The place where a group of traders does trade is called as a Market.
The initial form of trade was the Barter system where goods or services were exchanged for other goods and services. Later, the invention of currency simplified trade.
