Two computers can communicate over a public telephone network by using modems to convert digital signals into analog signals suitable for transmission over telephone lines. Each computer connects to a modem, which dials the phone number of the other computer's modem. Once a connection is established, the modems facilitate the exchange of data by encoding and decoding the signals back into digital form. This allows the computers to send and receive information effectively over the network.

Computers that are connected to each other create a network. These networks are often configured with "public" internet Protocol (IP) addresses -- that is, the devices on the network are "visible" to devices outside the network (from the Internet or another network). Networks can also be configured as "private" -- meaning that devices outside the network cannot "see" or communicate directly to them.

The X.25 protocol, adopted as a standard by the Consultative Committee for International Telegraph and Telephone (CCITT), is a commonly-used network protocol. The X.25 protocol allows computers on different public networks (such as CompuServe, Tymnet, or a TCP/IP network) to communicate through an intermediary computer at the network layer level. X.25's protocols correspond closely to the data-link …
