If a computer user wants to access the national database from a remote location, they will require a modem, communication software, and a telephone line. A modem is a device that allows the computer to communicate with other computers through a telephone line. Communication software is the program that helps the computer to communicate with other computers and access the national database. A telephone line is the connection between the computer and the telephone network that allows the computer to communicate with other computers. So, in simple terms, the user needs a modem and communication software to send and receive information, and a telephone line to establish the connection.
