Allows the end devices like a PC or laptop to access the outside world through the Internet.Ģ. While by configuring VPN in routers it can work in client-server architecture, and be used for sharing data, voice, hardware resources and video for WAN networks also.ġ. The modem is also used for data transfer and backup process but only for short distance and the process is slow. Data storage and backup of huge capacity.ĥ. In fact, the routers are a basic building block of the mobile communication system.ģ. The use of the modem is limited to only LAN connectivity but the routers are used for LAN as well as WAN communication networking. The details are discussed after the end of table.ġ. But it is widely used these days for other purposes also. The basic application of the modem is to connect the end users with the Internet. The modes are entirely different from the modem as the router works on the network layer. The details has been explained in the end of table. The routers also have the Wi-Fi port for wireless connectivity. The router has the Ethernet and gigabit ports to connect with the different network devices and other networking systems. It doesn’t provide the direct connectivity with the ISP as it doesn’t work at the physical layer. Therefore the devices which are associated with a router can access the Internet via a modem. The modem and router are physically connected with each other. The network can be a set of computers or a set of computers and switches etc.
It is placed between a modem and the network system. It connects the ISP to the single PC for the home or office network connections. The connectivity is done by the Ethernet port available with the modem. It is placed between the telephone line and the PC or router.It provisions connectivity with both wireless or wired like optical fiber, telephone line medium. Thus it is difficult for the unwanted material to enter the network by means of the router. The router uses a firewall to examine the incoming data packets and filters the unwanted data packets by using the firewall and other antivirus software. Thus any threat can easily get access to the network through a modem. It delivers the information as it is in the form it derives it from the ISP without checking any security threats as it is not smart enough to get it examined. The router is one of the basic building blocks of the WAN communication system. It routes the data packets among the networking devices and the different networking systems. If we need to connect only one computer to the Internet then the modem can do it, it doesn’t require the router. The modem brings out the requested data from the ISP to the end device like a PC or router. 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.
