We explain the difference between modem and router in tabular form. No part of our life is left untouched on the Internet. We live in a digital age and we are surrounded by various digital devices that run with the help of the internet. router and modem in tabular form
How many of us know the underlying architecture of the Internet? o How many of us know how we connect to the Internet? Only a few. router and modem in tabular form
But having a basic understanding of some terms can help you figure out how and why of this wonderful connection.
We all know that modem and router are essential for internet connectivity, but people mistakenly swap them while using them.
Both are very distinctive and it is essential to understand the difference between modem and router to know what performs what action. router and modem in tabular form
The modem converts analog cable or telephone signals into digital data through modulation so that connected computers can understand them, and conversely demodulates digital data into analog signals so that they can be sent back to standard phone lines. router and modem in tabular form
A router is a hardware device that routes data within or from a local area network to another network.
The router authenticates the user or connected machines and allows connection only between them.
Comparison table between modem and router (in table form)
Comparison Modem Router Parameter
|Definition||A modem is hardware that modulates the analog signal from the phone or cable to the computer and demodulates from the computer to the phone or cable.||A router is a piece of hardware used to connect or route data within one or more local area networks.|
|Purpose||It is a device that carries information from the Internet to your local area network.||It is a device that routes the information to the respective computer connected to the local area network.|
|Internet access||A modem is required to access the Internet as it connects your local area network to the Internet service provider.||The router is not essential to access the Internet. router and modem in tabular form|
|Process||The modem receives the analog signal from the phone and modulates it to digital form, ie ‘0’ or ‘1, and demodulates it from digital to analog.||The router routes the data packets to the respective computer based on the IP mentioned in its header.|
|Operation layer in the OSI model||Data link.||Physical layer, data link layer, network layer.|
|Cable used||RJ45 for router and RJ11 for telephone.||RJ45 for the computer.|
|Safety||The modem transfers the data without any authentication and verification, so security is not guaranteed.||The router checks each data packet through the information stored in its header and then only transfers the same. Therefore, security is guaranteed.|
What is the modem? router and modem in tabular form
The modem acts as a communication bridge between your LAN (local area network) and the Internet.
Modem means modulator-demodulator means that it modulates the analog signals of the telephone lines to the form of digital bits (‘0’ or ‘1’) so that they can be easily encoded and transferred from the sending computer.
And at the receiving end, it demodulates digital to analog and decoded signals. router and modem in tabular form
It can be connected to any infrastructure, that is, telephone, cable, fiber or satellite, also providing the standard Ethernet cable output that you can connect to your individual computer or to any router to access the Internet.
In addition to fiber optics, a modem is essential to access the Internet. The types of modem that exist are dial-up, DSL (broadband modem), cable modem, and mobile broadband.
The modem does not guarantee security as it only transfers the packet or information as it is received.
What is the router?
A router is a device used to connect or route data within one or more local area networks.
Route the data packets to their respective destination using the IP address mentioned in the header of the data packet.
The router is used to connect two LAN or WAN or LAN and WAN. The router is used only to distribute the data packets to a particular computer.
The RJ45 cable is used in the router to connect the computer to the network. router and modem in tabular form
Security is guaranteed in the router as it examines each received data packet and passes it to the recipient only if it is okay and then after identifying the physical address it routes it to the specific destination.
Thus, it saves the computer and network from possible harmful threats or attacks. The router is not essential to access the Internet.
In the OSI model, the router operates at the physical, data link, and network layer. router and modem in tabular form
Main differences between modem and router
Knowing the difference between modem and router helps us understand technical terminology as well as its actual purpose and operation,
- A modem is a device that modulates and demodulates signals, that is, from analog to digital and from digital to analog, while a router is a device that is used to connect or route data within one or more local area networks .
- A modem converts packet data signals from the Internet to the local area network and vice versa, while a router scans, analyzes, and distributes the data packet to route it to its respective destination or receiving computer or network.
- The modem operates at the data link layer of the OSI model, while a router operates at the physical, data, and network layers.
- The modem does not validate or filter the information that enters the network, thus it represents a threat to the network, while a router filters the data packet and the base of the IP address mentioned in the header routes them to the respective destination, therefore safe enough. .
- In the modem, RJ45 is used to connect the router and RJ11 for the telephone line, while in a router, RJ45 is used to connect the computer networks.
- A modem is necessary for Internet connectivity, while a router is not essential to access the Internet.
The Internet is an undeniable necessity today, both on a personal and professional level. router and modem in tabular form
From buying groceries to booking travel tickets or attending meetings via video conferencing to teaching online classes, everything is possible over the Internet.
Location has become irrelevant as no matter where you are, you can do whatever you want over the internet. But to access it you need the installation of some devices, that is, modem and router. router and modem in tabular form
As new technologies knock on doors every day, some of the ISPs offer embedded devices that combine modem and router functionality in one device. router and modem in tabular form
