What are the two types of signals used to communicate a message in a network and how are they different? What device converts one type to the other type?

The two types of signals used to communicate a message in a network are analog and digital signals. In the textbook, "Management Information Systems: Managing the Digital Firm," Laudon & Laudon describe an analog signal as " a continuous waveform that passes through a communications medium." An example of devices that use analog signals are audio communication devices, such as a telephone handset, computer speaker, or iPhone earphone. While a digital signal is defined as "a discrete, binary waveform" that computers use, which are "represented as on-off electrical pulses." These two types of data are different in the way the data is communicated, audio versus information strings of data through bits. A modem, also known as a "modulator-demodulator," is the device that must be used to convert digital signals into analog signals, and vice versa. This data is then sent and received over various networks, such as telephone lines, cable lines, or wireless media.
