Cash
Cash is a form of currency, such as banknotes or coins. There is usually different sorts in every country.
Bookkeeping and finance
In bookkeeping and finance, cash can also refer to checks, money orders, cashier's checks, bank drafts, or traveler's checks. In all these forms, the term indicates the most liquid form of assets, which have a fixed value and can be easily converted to currency: "ready money". For example, wages or salaries paid as "cash" (as opposed to, e.g., stock options) would in most countries normally be paid with checks or direct bank deposits, which are trivially convertible to currency.
