Trading
Trade, or commerce, involves the transfer of the ownership of goods or services, from one person or entity to another, in exchange for money, goods or services. A network that allows trade is called a market. The original form of trade saw the direct exchange of goods and services for other goods and services. Trade exists due to the specialization and division of labor, in which most people concentrate on a small aspect of production, but use that output in trades for other products and needs.
