A modem, short for modulator-demodulator, is a specialised device designed to modulate and demodulate signals for digital data transmission over telephone lines, cable networks, or wireless connections. These networking and Wi-Fi devices are significant in connecting computers and other compatible devices to the internet. The primary function of a modem is to convert digital data from a computing device into a format suitable for transmission over communication channels and vice versa. This process ensures efficient and reliable internet access. Modern modems are equipped with advanced technologies that support higher data transfer rates and improved security features, enhancing user experience and offering robust connectivity solutions.
