A device that serves to transform data in communication technology.
The term “modem” is a combination of the words modulator and demodulator. When sending, the modem modulates digital data 0 and 1 into an analog signal and transmits it over telephone lines, while when receiving, the modem demodulates that data from the analog signal into digital data. Today, the speed of transmission of this data reaches 56 KB per second, a figure that was previously much lower, only 300 bits. Today's modems use quadrature amplitude modulation in order to transmit larger amounts of data. There are also ADSL modems and cable television modems today. The goal is to produce a signal that can be easily transmitted and can be decoded to reproduce the original digital data. The best example is the modem, which converts the digital digits 0 and 1 of a personal computer into tones that can be transmitted over telephone lines, and when this data is received, on the other hand, those digits 0 and 1 are converted into the form used with USB and network connections. Today, most modems also have a fax integrated, which allows us to communicate with another computer as well as receive and send faxes.
