The modem also translates analog signals back into digital form for the receiving computer.Communications Networks

Essentials of Management Information SystemsChapter 6 Telecommunications, the Internet, and Wireless TechnologyLaudon, K. & Laudon, J. (2011). Essentials..Global Edition, USA, New Jersey: Prentice HallThis graphic illustrates the differences between digital and analog signals, and shows how digital signals can be sent to other computers over analog cables such as telephone and cable lines which are analog. Note that digital signals are representations of the two binary digits, 0 and 1, and are represented logically as on and off electrical pulses (in reality as different voltages). Ask students what MODEM stands for.
