A Modem (modulator-demodulator) is a device that modulates an analog signal to digital information. It also decodes carrier signals to demodulate the transmitted information. The main aim of the modem is to produce a signal that can be transmitted easily and decoded to reproduce the digital data in its original form. Modems are also used for transmitting analog signals, from Light Emitting Diodes (LED) to radio.
Router is a computer networking device that serves two primary functions: (1) create and maintain a local area network and (2) manage the data entering and leaving the network as well as data moving inside of the network. It also helps you to handle multiple networks and routes network traffic between them. In your home network, your router has one connection to the Internet and one connection to your private local network. Moreover, most routers also contain built-in switches that allow you to connect multiple wired devices.
