Dial Up Connection
An Internet account that can connect any stand-alone PC directly to the Internet. The account is used by having a PC-based (most often, Windows-based) software application dial-in to an Internet service provider (ISP). The software connects with the ISP and establishes a TCP/IP link to the Internet that enables your software to access Internet information. The PC that accesses a dial-in connection needs either a modem to connect via a regular phone line or a terminal adapter (TA) to connect via an ISDN phone line.
