The term internet is always linked to the terms router and modem (modulator/demodulator). But most of the people generally get confused, are both router and modem the same? Do they perform the same task? If not, how are they different from each other?

Marka, si loo xalliyo dhibaatadan dadka, maqaalkan, waxaad ku baran doontaa wax ku saabsan modem, router, shaqadooda, iyo faraqa weyn ee u dhexeeya labada.

Waa maxay faraqa u dhexeeya router iyo modem?^{(What is the Difference Between a Router and a Modem?)}

Haa, waxaa jira farqi u dhexeeya modem iyo router waana mid aad u fudud. Modem-ku waa mid ku xidha internet-ka, router-kuna waa kan ku xidha aaladda Wi-Fi-ga si aad si fudud ugu gasho internet-ka. ^{(A modem is one that connects to the internet and a router is one that connects your device to the Wi-Fi so that you can access the internet easily.)}Marka la soo koobo, router-ku wuxuu abuuraa shabakad u dhexeysa kombiyuutarada iyo aaladaha kale ee laga heli karo gurigaaga halka modemku uu ku xirayo shabakadaas, sidaas darteed, kombuyuutarkaaga iyo qalabka kale ee internetka. Labaduba waa qaybo lama huraan u ah gelitaanka internet-ka bilaa-waayirka ah iyo fiilooyinka leh ee gurigaaga ama meel kasta oo kale. Hadda, aan wax badan ka baranno modem-ka.

Modem

Erayga modem waxa uu u taagan yahay modulator/demodulator . Modemku waa qalab ama barnaamij u beddela xogta u dhaxaysa warbaahinta gudbinta si ay hal qalab ugu gudbiso qalab kasta. Waxa ay u ogolaataa kombuyuutarku in uu xogta ku soo diro xadhkaha telefoonada, xadhkaha fiilooyinka iwm. isaga oo isticmaalaya calaamadaha analoogga ah. Xogta waxaa lagu kaydiyaa aaladaha sida kombuyuutarrada si dhijitaal ah, laakiin marka la wareejiyo, waxaa loo gudbiyaa qaab mawjadaha analogga ah ama calaamadaha.

modem-ku waxa uu u beddelaa xogta dhijitaalka ah ee ku jirta kombiyuuterka una beddela calaamad koronto oo habaysan oo la isku dhaafiyo aaladaha iyada oo loo marayo xadhkaha fiilada waxaana calaamaddan korontadu ay hoos u dhigtaa dhinaca qaataha iyada oo loo marayo Modem si ay u soo ceshato xogta dhijitaalka ah.

Modem inta badan waxa uu leeyahay lights/LEDs xagga hore si aad si fudud u arki karto waxa hadda socda.

Asal ahaan, waxaa jira afar nalal/LEDs oo laga heli karo dhinaca hore ee modem u adeegaya ujeedooyin kala duwan.

1. Hal iftiin ayaa tilmaamaya in unugga uu helayo koronto.
2. Iftiin kale ayaa tilmaamaya in modemku uu xogta ka helayo bixiyaha adeegga internetka ( ISP ).
3. Midka saddexaad wuxuu muujinayaa in modemku si guul leh u dirayo xogta.
4. Midka afraad wuxuu muujinayaa in aaladaha ku xiran ay gelayaan i

Markaa, markaad aragto LED-ka ama iftiinka shaqaynaya ama libiqsanaya,^{(seeing which LED or light is working or blinking,)} waxaad si fudud u arki kartaa waxa modem-kaagu hadda qabanayo ama waxa hadda ka dhex socda. Haddii nalalka la soo dirayo ama la helayo ay libiqsanayaan, waxay la macno tahay in adeeg bixiyahaaga internetku uu leeyahay arrimo qaarkood oo aad u baahan tahay inaad la tashato.

Modemku wuxuu ku xidhaa isha internetka ee ISP gurigaaga ama meelaha kale ee aad rabto inaad ka gasho aaladaha intarneedka iyadoo la isticmaalayo fiilooyinka sida Comcast , fiber optics, satellite-ka ama xidhiidh kasta oo telefoon la garaaco. Adeegyada kala duwan waxay leeyihiin noocyo kala duwan oo modem ah mana isku beddeli kartid.

Si aad internet-ka uga gasho dhulka miyiga ah ee ay khadadka telefoonadu ka jiraan balse aanay jirin wax taageero ah oo loo fidiyo TV-ga iyo adeegyada internet-ka ku salaysan, DSL waxa loo isticmaalaa halkii xadhkaha casriga ah ee caadi ahaan gaabis ah.

Farqiga u dhexeeya modem iyo router^{(Difference between a Modem and a Router )}

Hoos waxaa ah faraqa u dhexeeya modem iyo router.

1. Shaqada^{(1. Function )}

Modemku waa sida tarjumaha u dhexeeya intarneedka iyo shabakada deegaanka. Modem-ku waxa uu calaamadda korantada u beddelaa calaamad dhijitaal ah oo waxa uu dejiyaa calaamadda dhijitaalka ah ee signalka analoogga halka router uu abuurayo shabakad oo uu u oggolaado qalabyo badan inay ku xidhmaan shabakaddan.

Haddii aad haysato hal qalab oo keliya, markaa uma baahnid wax router ah. Modemku waxa uu leeyahay deked Ethernet ah oo kumbiyuutarka ama qalab kasta oo kale ayaa si toos ah ugu xidhi kara dekedda Ethernet oo uu ka geli karaa internetka. Laakiin haddii aad leedahay aalado badan, markaa waxaad ku xidhi kartaa internetka adoo isticmaalaya shabakada uu sameeyay router ka dibna waxaad ku xidhi kartaa internetka.

2. Xiriirinta^{(2. Connections )}

Modemku waxa uu leeyahay hal deked oo kaliya waxana uu ku xidhi karaa hal qalab markiiba ie kombiyutarka ama router-ka. Markaa, haddii aad leedahay aalado badan, ma wada xidhi kartid iyaga oo isticmaalaya modem. Taasi waa sababta loo baahan yahay router.

Taas beddelkeeda, router-ku wuxuu ku xirmi karaa aalado badan hal mar isagoo sii maraya fiilooyinka Ethernet ama ^(Ethernet)Wi-Fi-ga^(Wi-Fi) .

3. Amniga^{(3. Security )}

Ma jiro hab-ammaaneed dhex-dhisan oo ku dhex jira Modem mana iska baadho xogta wax u nuglaanshaha amniga ah. Marka, waxay u gudbin kartaa hanjabaadaha dhammaan kombiyuutarada ku xiran.

Halka router uu ka kooban yahay firewalls sax ah si loo ilaaliyo amniga. Waxay si sax ah u hubisaa xirmooyinka xogta si ay u go'aamiso meesha ay u socdaan ka dibna waxay ka hortagtaa weerar kasta oo soo gala qalabka ku xiran.

4. Madaxbanaan^{(4. Independent )}

modem-ku waxa uu shaqayn karaa iyada oo aan la helin router waxa uuna ku siin karaa isku xidhka interneedka hal qalab.

Dhanka kale, router-ku wuxuu wadaagi karaa macluumaadka u dhexeeya qalabyo badan laakiin ma siin karo internetka qalabkan iyada oo aan lahayn modem.

5. Nooca qalabka iyo lakabka^{(5. Device type and layer)}

Modemku waa qalab shaqaynaya oo ku salaysan intarneetka kaas oo isticmaala lakabka labaad sida lakabka isku xidhka xogta^{(data link layer)} .

Router-ku waa aaladda iskuxiran ee adeegsata lakabka saddexaad ee shabakadda.

Goorma ayaad u baahan tahay modem ama router?^{(When do you need a modem or a Router?)}

Si loo sameeyo shabakad guri, labadaba modem iyo router ayaa loo baahan yahay. ^{(To set up a home network, both the modem and router are required.)}Haddii aad hal qalab ku xirayso internetka oo leh fiilo, waxaad u baahan tahay kaliya modem halka aysan jirin kiis noocaas ah oo aad isticmaali karto kaliya router. Waxaad had iyo jeer u baahan doontaa inaad isticmaasho Modem -ka iyadoo lala kaashanayo Router si aad u dejiso calaamadda bixiyaha adeeggaaga internetka ( ISP ).

Haddii aad hore u isticmaalaysay modem laakiin aanad ka helin xawaaraha la rabo ISP markaas waxaad isticmaali kartaa router si aad u dedejiso shabakadaada. Waxay leedahay xaddidaad xaddidan waxayna ku wareejisaa calaamadda dhammaan aaladaha ku xiran. Asal ahaan, waxa uu sameeyo routerkaaga waa in uu sameeyo isku xirka Wireless oo uu maamulo Wi-Fi gaaga ( Internetka^(Internet) ).

Sidaa darteed, tani waxay ku saabsan tahay modem iyo router oo ay weheliyaan qaar ka mid ah farqiga u dhexeeya labada.

What is the Difference Between a Router and a Modem?

The term internet is always linked to the terms router and modem (modulator/demodulator). But most of the people generally get confused, are both router and modem the same? Do they perform the same task? If not, how are they different from each other?

So, to resolve this dilemma of people, in this article, you will learn about a modem, a router, their working, and major differences between the two.

What is the Difference Between a Router and a Modem?

Yes, there is a difference between a modem and a router and it is very simple. A modem is one that connects to the internet and a router is one that connects your device to the Wi-Fi so that you can access the internet easily. In short, a router creates a network between the computers and other devices available in your home while a modem connects that network and thus, your computers and other devices to the internet. Both are necessary components for wireless and wired internet access in your home or at any other place. Now, let’s learn more about a modem.

Modem

The term modem stands for modulator/demodulator. A modem is a hardware device or program that converts the data between the transmission media so that it can be transmitted from one device to any other device. It allows a computer to send the data over the telephone lines, cable lines etc. using analog signals. The data is stored in devices like computers digitally, but when transferred, they are transferred in the form of analog waves or signals.

A modem converts the digital data present in a computer into a modulated electrical signal for the transmission over devices through cable lines and this electrical signal is demodulated at the receiver side by a Modem so that it can recover the digital data.

How does a Modem work?   

A modem usually has lights/LEDs at their front so that you can easily see what is going on at the moment.

Basically, there are four lights/LEDs available at the front of a modem serving different purposes.

1. One light indicates that the unit is receiving power.
2. Another light indicates that the modem is receiving data from the internet service provider (ISP).
3. The third one indicates that the modem is successfully sending data.
4. The fourth one indicates that the connected devices are accessing the i

So, by seeing which LED or light is working or blinking, you can easily see what your modem is currently doing or what is currently going inside it. If the sending or receiving lights are blinking, it means that your internet service provider is having some issues and you need to consult them.

A modem connects the source of the internet from the ISP to your home or other places where you want to access the internet devices using cables like Comcast, fiber optics, satellite or any dial-up phone connection. Different services have different types of modems and you cannot interchange them.

To access the internet in rural areas where telephones lines exist but there is no support for cable-based TV and internet services, DSL is used instead of the modern cables which are typically slower.

Pros and cons of a Modem

Pros

• It connects to an ISP.
• ISP Compatibility
• It converts a digital signal into an analog signal for the transmission over a cable.

Cons

• It cannot create a local network and run Wi-Fi.
• It doesn’t connect multiple devices to the internet.

Router

A router is a networking device that transfers data packets between computer networks. Basically, a router is a small box that joins two or more networks like the internet and the local network. The data sent by the internet like an email or any web page is in the form of packets. These packets are then transferred from one router to another router through the internet until it reaches the destination. When a data packet reaches any of these lines, the router reads the destination address of that data packet and forwards it to the next network towards its destination.

The most familiar type of routers are home routers or office routers. The routers are stand-alone devices. Routers have a dedicated, colour-coded Ethernet port that it uses to physically connect to the router like WAN (wide area network) and four additional Ethernet ports for LAN (local area network).

How does a Router work?

The router comes in all sizes and prices. The wireless ones include two external antennas or more depending on the model. Also, the connection speed of the router depends on the proximity of the router.

The working of the router is very simple. It connects multiple networks and routes network traffic between them. To understand the working of a router in simple words, just imagine a router as an intermediary between the internet connection and the local network. The router also offers protection to your devices so that they do not get exposed directly to the internet. You cannot directly connect to the internet using just a router. Instead, your router must be used in conjunction with a Modem as it transmits the traffic over the internet connection.

Pros and cons of a Router

Pros

• Simultaneous connection to several devices
• Security and Adaptability
• VPN utilization
• Wireless Technology
• Portability

Cons

• Data Overhead
• Complicated Setup
• Expensive

Difference between a Modem and a Router

Below are the differences between a modem and a router.

1. Function

A modem is like a translator between the internet and the local network. A modem modulates the electrical signal into a digital signal and demodulates the digital signal into an analog signal while a router creates a network and allows multiple devices to connect to this network.

If you have only one device, then you do not need any router. A modem has an Ethernet port and a computer or any other device can connect directly to this Ethernet port and access the internet. But if you have multiple devices, then you can connect to the internet using the network created by a router and then can connect to the internet.

2. Connections

A modem has only one port and can connect to only a single device at a time i.e either to a computer or a router. So, if you have multiple devices, you cannot connect them all using a modem. That is why a router is required.

On the contrary, a router can connect to multiple devices at a time either through the Ethernet cables or the Wi-Fi.

3. Security

There is no in-built security mechanism in Modem and it does not scan the data for any security vulnerability. So, it can pass threats to all the computers connected.

While a router contains proper firewalls to provide security. It properly checks the data packets to determine their destination and then prevents any attacks from entering into the connected devices.

4. Independent

A modem can work without any router and can provide internet connectivity to a single device.

On the other hand, a router can share information between multiple devices but cannot provide internet to these devices without a modem.

5. Device type and layer

A modem is an internet-based working device which uses the second layer i.e. the data link layer.

A router is a networking device that uses the third-layer i.e. the network layer.

When do you need a modem or a Router?

To set up a home network, both the modem and router are required. If you are connecting a single device to the internet with a wire, you only need a modem while there is no such case where you can use just a router. You will always need to use a Modem in conjunction with a Router in order to decode the signal from your internet service provider (ISP).

If you’re already using a modem but not getting the desired speed from the ISP then you can use a Router to speed up your network. It has bandwidth limits and it circulates the signal to all the connected devices. Basically, what your router does is that it creates a Wireless connection and manages your Wi-Fi (Internet).

Hence, this is all about a modem and a router along with some differences between the two.
