The concept that refers to the sale, transfer, or exchange of goods and services is **trade**.
Trade is the process of buying and selling goods and services between individuals, companies, or countries. It involves the exchange of something valuable, such as money, for a product or service.
For example, when you go to a store and purchase a book, you are engaging in trade. The store is selling you the book, and you are giving them money in exchange. This transaction is a form of trade.
Similarly, when different countries exchange goods with each other, it is also called trade. For instance, if one country produces cars and another country wants to buy those cars, they will engage in trade by exchanging money for the cars.
Trade plays a crucial role in the global economy as it allows people and businesses to obtain the goods and services they need or desire. It promotes economic growth, creates job opportunities, and helps to establish connections between countries.
