A modem (modulator-demodulator) is a device that converts digital data into analog signals and vice versa. 🌐 It allows computers to communicate over telephone lines or other analog media. Think of it as a translator between digital and analog worlds. Unlike a router, which directs network traffic, a modem connects your network to your internet service provider (ISP). Modems are essential for accessing the internet via traditional phone lines. While fiber optic connections are gaining popularity, modems still play a role in many homes and businesses.
