Difference between Modem & Router | Top Notch Guide Of Modem Vs Router

Nowadays everyone is using modems in their homes and workplaces having inbuilt Routers and wireless network connections to their devices, due to which people who have been using the internet from its initial era only know the difference between Modems and Routers. So here is the elaboration of these two networking devices

What Are MODEMS

A modem is a networking device that connects your system to the outer world internet. A modem converts the analog signals coming from the internet supplier to the digital signals because our computers can execute only digital signals. 

Modulation is the process of converting analog signals to digital signals. Likewise, Modem also converts the digital signal given out by the computer system to the outside bigger internet network after converting them back to analog signals, and demodulation is the process of converting digital signals to analog signals. 

The word “Modem” forms when we put these words modulation and demodulation in some initial letters. It works as a gateway to your Device to the internet.

Types

There are various types of Modems like analog, cable, DSL.

  1. Analog Modem

 An analog modem is the eldest type of modem. It uses a telephone connection line to convert signals due to which one may not be able to use phone for calling purposes while streaming or using an internet network. 

  1.  DSL Modem

A DSL modem is a newer version of the analog modem as it also uses telephone connection lining to convert signals but in this type of modem, we also get the facility to use the phone for calling purposes while surfing the internet. Because in DSL the frequencies of both calling and internet connections separate from each other, so with this we can perform both the functions simultaneously. A DSL is not as fast as cable as they do not share internet bandwidth, they have their dedicated connections. 

DSL modems have a download speed of 5-100Mbps.

Types of DSL

  • ADSL(Asymmetric Digital Subscriber line)

In Asymmetric Digital Subscriber line DSL, the download speed of the network is more than the upload speed.

  • SDSL(Symmetric Subscriber line)

In symmetric subscriber line DSL, the download speed of the network is equal to the upload speed.

  1. Cable Modem

Cable Modems are the modems that use general-purpose TV cables for getting internet networks from internet providers. In cable modems, the router connects to computers with coaxial wire. These types of modems provide the download speed of range 25Mbps to 400Mbps. 

Here in this form of service, the same provider distributes network to the customers or shares the same bandwidth due to which speed of internet provided to customers may get low for sometime when the number of users increases at the same time. This is not preferable for long-distance internet providing services because it contains copper wires which may have electromagnetic interference on the transmitted data.

*Extra Features

Other than converting signals modems also have to look at whether the transmitted data pack by the internet providers is correct for your system or not. If they are not correct or harmful for your system they are sent back by the modems.

Some US-based Modems manufacturing companies are ATMT, D-Link, Cisco, Motorola, etc.

What Are ROUTERS

 A router is a networking device used for avoiding the traffic that happens during the transmission of data by checking the IP address of the system to which the data has to be sent whether it is of its network or not.

The modem ensures that the data is sent to the needed device only among all the devices connected to the same network.

Ex: If your phone and PC are connected to the same network then its routers work to play a video on your mobile only if you have played it on mobile. It makes it possible to use different devices on the same network and also to share various types of data like files, folders, drives, etc. These are the modified version of hubs which does not use to send the data only to the needed device but to every possible port connected to it.

Since it checks the IP Address on the data packets, it not only removes the unwanted traffic but also provides data security. For security concerns only they also have passwords facilities on them. By which Router provides access to the internet network only to the device which enters the correct password as saved by the owner in its settings.

Types

1. Wired routers

Wired Routers are the routers that connect to the devices with wires.

2.Wireless Routers

Wireless Routers are the routers that connect to devices with the digital wireless network without any direct physical connection. 

Some US-based Routers manufacturing companies are Cisco, Nokia, Juniper.

Frequently Asked Questions


Q1: Why do we need a Modem and a Router?

If you want to use the network just for one device only, then you do not need a router. but if you have to connect more than one device to the same network then you need a Router with your Modem.

Q2: Is there any Combo of Modem and Routers?

Yes, nowadays integrated Modems are present in the markets provided by the internet provider companies which contain inbuilt wireless Routers in them.

Q3: Are modems and routers the same?

No, a modem connects a device to the internet while a router connects the devices to WiFi.
