The main purpose of using a router is to connect various networks. The router also makes ensures that the data reach their intended destination.The routers determine where to transmit data from one computer to another.The router creates a connection between different media/devices.Router split your internet connection to all of your devices.The router creates a local area network(LAN).Router helps to connect those to your home or WiFi network which then allows you for wireless communication. The router is required when you want to connect multiple devices to the network or if it is required to connect that device wirelessly. It is also used to create and maintain LAN(Local Area Network).The router is also used to maintain multiple networks and route traffic between them.The router is a networking device used to manage the data entering and leaving the network as well as data transmitting within the network.Offers protection against the overload problem at the receiver end also.The modem also performs line signaling and control at the receiver end.To receive the analogue signal and demodulate them into digital form.It offers protection against line overload and other problems.If the modem is designed to dial in absence of a user then it also transmits a dialing signal.For performing the line controlling and signaling to other ends of a phone line.For converting the digital data (0s and 1 s) into an analogue signal.

And for demodulating the digital signal into an analogue signal. Modems are mainly used for modulating the analogue signal to a digital signal. The modem is a device that is also used for transferring analogue signals from LED( Light Emitting Diodes) to radio.The main purpose of a modem is to generate a signal that can be easily transmitted and to decode to reproduce the digital data into its original form.It is also used for decoding carrier signals to demodulate the transmitted data.The modem is a device that is used to modulate the analogue signal to digital signals.A modem is used for modulation and demodulation.
