Trade is a vital component of commercial activities, encompassing the exchange of goods and services for profit. It can be classified into two primary types: internal trade, which occurs within the country's borders, and external trade, which occurs internationally involving imports and exports. Internal trade is further divided into wholesale (goods sold in bulk) and retail (goods sold to the end user), while external trade involves the complexities of international trade regulations, tariffs, and currency exchanges. Trade not only facilitates economic growth but also enhances consumer access to a diverse range of products, thereby contributing to overall economic development.
