CIMM DEFINITION: A data communications device. Modem is a combination of two words, modulate and demodulate. Strictly speaking, a Modem is a device that accepts a digital signal, then converts or modulates it into an analog signal that another Modem can convert back, or demodulate into digital form again. A Modem’s speed and dependability are adversely affected by electro-magnetic interference, or static. (Source: CableLabs)
