Modem vs Router: Routers and modems are two most common computer peripherals but still many people doesn’t know the difference between Modem vs Router and people are confused about how they function. Though both look similar, they have different purposes. But don’t worry we broke down the functions of each to make them easy to understand. Modem and router are different with two separate roles on a network.
Modem vs Router:
If you need internet at your home or business, you have to have modem. Modem is the one which brings internet to your house or to your business.A modem establishes and maintains dedicated connection to your internet service provider which helps to provide access to the internet. Here is the reason why you need to use modem. There are two different signals which are used on computer and on the internet. A modem helps to transfer those signals into usable form. Let me make it more clear to you. A computer can read only the digital signal where as the signals coming out from the internet are analog signals. Now what modem does it, it demodulates the incoming analog signals into a digital signal which helps the computer to understand it.
What is Modem:
Modem means modulator and demodulator which is exactly what a modem does. A modem modulates outgoing data from a computer and demodulates incoming data from the internet. Now let us see what a router is. Routers can be of different types which can be used in businesses and larger organizations. Smaller routers can be used in small businesses and out homes. But every type of router basically does the same thing.
What is a router
A router routes your internet connection to all of your devices at your home or business. It directs passes your internet connection to all of your tablets, phones, computers, iPads and many more. A typical home office router has a built in switch with many ports which help to connect multiple devices using ethernet cable connection.
For understanding purposes, let us use small office/home office router which most of us see everyday.
In short router acts as a wireless access points by indirectly helping wireless devices to have internet access
Difference between modem and router
Technically speaking, you don’t need a router if you need only one device to be connected to the internet. This is because when you just have a single device, you can directly plug that device’s network cable directly to the modem. But generally this is not the situation in most houses and businesses.
For instance, I myself live with other roommates in our apartment at Malden. Four people live together. We all need internet and each person cannot have their own internet connection which is just a mere waste unless you have some issues with other roommates.Similarly in small businesses like a small grocery store there are employees who need to use wifi to run the business and some customers may demand wifi when they are sitting and drinking coffee.Thereby in most situations it is not uncommon to have many people using the same internet connection. Here comes the router as a savior.
Besides knowing the difference between a router and a modem, now let us know the types of modem out there in the market. There are also different types of modems. The two most common types of modems are DSL modems and cable.
A) Cable modems have a coaxial connection which is the same type of connector found on a TV or cable box. This connects to a cable port on the wall.
B) DSL modems have a telephone connector, which is also called as an RJ-11 JACK, which connects to a telephone socket on the wall. By the way, have you ever wondered how you get your IP address? Router provides a local IP address to each connected device, but all the connected devices have the same external IP address which is assigned by your internet service provider.
