How Do Routers Work? Here's the explanation


How Routers Work


The word router is familiar in the networking world and is an important piece of technology that most of us have, but many of us don't really understand. In fact, most people don't even realize what a router is technically and how a router works. The following is an explanation of How Routers Work.

How Do Routers Work?


Simply put, routers connect devices in a network by forwarding data packets between them. This data can be sent between devices, or from devices to the internet. Routers do this by assigning a local IP address to each device on the network. This is to ensure that the data packet ends up in the right place.


Think of this data as a courier package, it needs a shipping address so that it ends up at the right recipient. Our local computer network is like a suburban street, just knowing this location in the world at large (i.e. the World Wide Web) is not enough.


The package can easily end up in the wrong house with limited information. Thus, the router ensures that each location (device) has a unique number so that the packet goes to the correct address.Â


If we need to return data to the sender, or send our own packets, our router does this job too. Even though it handles each packet separately, the Router does this so quickly that it feels instant, even when multiple devices are sending data at once.

Why Are Routers Different From Modems?

Since modern modems often come with a built-in router, the distinction between the two types of hardware is often misinterpreted. But most people who have internet service will know that the two devices have different functions.


We need a modem to connect to the internet through our ISP, while we need a router to connect many devices in the network, including our modem. Therefore, routers allow our modems and many devices to transfer data from one location to another.


A modem is a channel that sends data to and from the internet. We need a modem because of the different types of signals used by computers compared to the internet in general. Computers and mobile devices use digital signals, while the internet works on analog signals.


The modem converts these signals to the correct format. This is where the device gets its name, namely: modem which comes from the words modulator and demo modulator. This signal conversion is a special function of the modem. Actually coordinating these signals is the job of the router.


What Are Routers Used For? When We Need It


Often in a house that has a PC, we only need a modem to connect to the internet. Technically, if we only want to connect one device, we can still use the modem only. Although for security reasons and future flexibility, it is best to use a router even with only one device on our network.


But if our house has more than one device, router is very important. Think back to the example of street names with our house numbers. If there is only one house on the street, we don't need the house number because that's the only location. But when there are several houses on the street, we need a local address.


We need a router not only when we want to connect multiple devices to the internet, but also if we want to connect multiple devices to each other. Without the internet, we can still create a local network of computers and other devices. It allows us to transfer and share files with certain devices on the network, including printers, scanners, or other computer devices. We must always remember that a local network can exist without internet or a modem, but cannot exist without a router.


Difference Between Wired And Wireless Router


The difference between wireless and wired routers is the type of connection each device allows. Wired routers only have a wired LAN port, while wireless routers (also known as Wi-Fi routers) include an antenna and a wireless adapter that allows devices to connect wirelessly.

Since modern modems often come with a built-in router, the distinction between the two types of hardware is often misinterpreted. But most people who have internet service will know that the two devices have different functions.
