Central bank digital currencyA central bank digital currency (CBDC) is a digital version of an official currency, created by a central bank rather than by private companies. Unlike cryptocurrencies such as Bitcoin, CBDCs are issued by a state and may work alongside physical cash. As of 2024, the Bahamas, Jamaica, and Nigeria have launched CBDCs, and 134 countries are researching their own versions while other jurisdictions, such as Florida, have banned CBDCs citing privacy concerns.
Virtual currencyVirtual currency, or virtual money, is a digital currency that is typically unregulated, issued and usually controlled by its developers, and used and accepted electronically among the members of a specific virtual community as part of a virtual economy.
Fiat moneyFiat money or fiat currency is a type of government-issued currency, generally created by a central bank, authorized by government regulation to be legal tender but not backed by a precious metal, such as gold or silver, nor by any other tangible asset or commodity. Since the end of the Bretton Woods system in 1976 by the Jamaica Accords, all the major government currencies in the world are fiat money. Fiat money generally does not have intrinsic value nor a use value.CurrencyA currency is a standardized form of money, in use or circulation as a medium of exchange, for example banknotes, coins, electronic balances in online bank accounts, and central bank digital currencies (CBDCs). A more general definition is that a currency is a system of money in common use within a specific environment over time, especially for people in a nation state.
MoneyMoney 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. The primary functions which distinguish money are: medium of exchange, a unit of account, a store of value and sometimes, a standard of deferred payment.
CryptocurrencyDigital asset using a distributed ledgerCryptocurrency is a type of digital asset that uses distributed ledger, or blockchain, technology to enable a secure transaction. Individual coin ownership records are stored in a digital ledger or blockchain, which is a computerized database that uses a consensus mechanism to secure transaction records, control the creation of additional coins, and verify the transfer of coin ownership.
Stored-value cardA stored-value card (SVC) or cash card is a payment card with a monetary value stored on the card itself, not in an external account maintained by a financial institution. This means no network access is required by the payment collection terminals as funds can be withdrawn and deposited straight from the card. Like cash, payment cards can be used anonymously as the person holding the card can use the funds.
Computer fileA computer file is a named collection of data treated as a unit by the system that manages it. Today, this system is called a file system. Many older computer systems lacked a distinct file system per se, yet a management feature is required in order to provide a file abstraction. Files can be shared with and transferred between computers and mobile devices via removable media, networks, or the Internet. Different types of computer files are designed for different purposes.

It may be stored in multiple computers located in the same physical location (e.g. a data centre); or maybe dispersed over a network of interconnected computers. Unlike parallel systems, in which the processors are tightly coupled and constitute a single database system, a distributed database system consists of loosely coupled sites that share no physical components.
DatabaseAn SQL select statement and its resultIn computing, a database is an organized collection of data or a type of data store based on the use of a database management system (DBMS), the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS additionally encompasses the core facilities provided to administer the database.*As an Amazon Associate I earn from qualifying purchases.
