Name and explain money notes
​

Economists identify four main types of money – commodity, fiat, fiduciary, and commercial. All are very different but have similar functions.

Money comes in three forms: commodity money, fiat money, and fiduciary money. ... Commodity money derives its value from the commodity of which it is made, while fiat money has value only by the order of the government. Money functions as a medium of exchange, a unit of account, and a store of value.

Money is any item or verifiable record that is generally accepted as payment for goods and services and repayment of debts, such as taxes, in a particular country or socio-economic context.[1][2][3] The main functions of money are distinguished as: a medium of exchange, a unit of account, a store of value and sometimes, a standard of deferred payment.[4][5] Any item or verifiable record that fulfils these functions can be considered as money.
