Modem- It transforms digital information from your computer into analog signals that can transmit over wires by modulating and demodulating electrical impulses sent through phone lines, coaxial cables, or other types of wiring.
Router- It is “home network,” as we’re using it here, refers collectively to the system of interconnected devices in your home plus your router itself. Its responsibility is to direct, or route, data between devices in your home, as well as between those devices and the wider internet.
