Many public places, businesses and government offices utilise public information systems. The networks conduct various types of transactions. Large amounts of information are obtained and stored on these networks to provide the services that each network is programmed to perform.
ATM machines are an example of a public information system. An ATM is used by members of the banking public to access account records and to perform transactions and account maintenance. These machines are networked to banks by a common network that allows the machine to perform the necessary functions to complete the requested transaction.
