US Dollar (USD)
Definition: The United States Dollar (symbol: $; code: USD) is the official currency of the United States and several other countries. It is the world's primary reserve currency and the most widely used currency in international transactions. The US Dollar is subdivided into 100 cents.
History: The USD was adopted as the official currency of the United States in 1792. It was originally backed by silver and gold, but since 1971, it has been a fiat currency, meaning its value is not directly tied to any physical commodity but is determined by market forces and government policy.
Usage: The USD is used as a standard currency in global trade, financial markets, and foreign exchange reserves. Many countries peg their own currencies to the USD for stability.
