A modem router is a device that connects a local area network (LAN) to the internet. It serves as a bridge between the LAN and the internet and allows connected devices to access the internet. To do this, the modem router takes the signal from an ISP (internet service provider) that comes into the router via a coaxial cable, an optical fiber cable, or a telephone line, and converts it into a signal that can be used by the connected devices. The modem then takes the signal from the connected devices and converts it into a signal that can be used by the ISP for access to the internet. This process is known as modulation–demodulation (modem).
