![]() The modem plays a very vital role in the communication system as it is an essential part of the networking system for connecting any device to the ISP. ![]() The router permits various network devices to connect into the network. It doesn’t perform any type of modulation and demodulation function, but it routes a data packet between source and destination end by following the shortest path and securely directs the data packet by following the routing table. It modulates the digital signal of the computer or router to the analog signal of the telephone line so that easily understood by the telephone line when getting through it and performs the demodulation function at the other end by converting the analog signal which comes from the telephone line into a digital signal for the network device like PC. It works on the physical, data-link and network layer of the ISO-OSI reference model and maintains the routing table to forward and route the data packet to the desired destination path. It works on the data-link layer of the ISO-OSI reference model and doesn’t have any inbuilt intelligence. The router is a networking device which associates various networks with each other for LAN and WAN networks.

Modem and Router – Connection to the Internet ![]() The connection between the modem and the networking device is done by using RJ45 cable and between the modem and telephone line is by using RJ11 cable. The main purpose of using a modem is that it connects the networking system or device to the Internet service provider (ISP) and we can get access to the Internet only by using a modem. The modem performs the modulation and demodulation function in between your networking devices such as a computer or router and the telephone line.įurther reading => Top Wi-Fi Routers available in India It works on the data-link layer of the ISO-OSI reference model and provisions the transmission of data packets.
