| | Modems (Linktionary term) |
| | In contrast, digital-to-analog conversion can produce a near-perfect analog representation of a signal so that no information is lost. | | | Modems (modulators/demodulators) are data communication devices that convert digital signals to analog signals, and vice versa. | | | Note that in the figure, the computer's outgoing digital signal is converted to an analog signal for transmission across the copper local loop to the CO. At the CO, the analog signal is converted back to digital for transmission across its digital backbones. |

| | Once a signal has traveled over the telephone line, a second modem is required at the other end of the line to reconvert the transmitted signals from analog to digital. | | | A modem is needed because computers are digital, meaning that their signals are made up of discrete units, while most telephone lines are analog, meaning that they carry signals that are continuous instead of discrete. | | | E-mail messages are generally sent from and received by mail servers - computers that are dedicated to processing and directing e-mail. |
