Router is: Definition, Function and How it Works
A router is a device that allows us to connect several devices to the internet simultaneously, such as laptops, smartphones, to smart TV.
However, for many people, especially those who are new to the internet network, this term may still sound foreign. So, what exactly is this thing, how does it work, and how is it different from a modem?
Let's discuss it thoroughly in this article so that you better understand its important role in your digital life.

A router is a network device that functions to direct data between several devices in a local network to the internet or another network.
With this, you can connect several devices such as smartphones, laptops, or tablet to the internet network simultaneously via WiFi or LAN cable.
Routers have several main functions that make them an important component in an internet network, including:
The most basic function of this technology is to connect devices in the home or office to the internet. Without it, devices can only connect directly to the modem, and usually only one device can connect to the internet. With a router, all devices can be connected simultaneously through the same network.
The router also functions to distribute WiFi signals so that your device can connect to the internet without the need for cables. This certainly makes internet usage more practical, especially for mobile devices such as smartphones or tablets.
Its function is also to manage the data traffic that goes out and into the network. For example, when you open a website or watch a video, the router will ensure that the data you need is forwarded to your device quickly and efficiently.
Its function also has security uses with a firewall that protects the network from unauthorized access or attacks from outside. Many modern routers come with additional security features, such as setting a WiFi password or the option to block certain sites.
How does a router actually work to connect devices to the internet? The way a router works is arguably quite simple but very important. When you connect a device to a router, either via WiFi or a LAN cable, the device will be assigned an IP address by the router.
The router then acts as a “gatekeeper” between your local network (e.g. at home) and the internet. When you access a website, the router will direct the data request from your device to the internet network.
The data is then sent back through the router and forwarded to your device. All of this process takes place very quickly, with almost no delay, so you can surf the internet without any obstacles.
Many people often confuse a router with a modem because they look similar and are often located in the same place. However, their functions are very different. Let's take a look at the differences:
A modem is a device that connects your local network to your internet service provider (ISP). A modem works by converting signals from your ISP (usually via telephone lines, fiber optic, or TV cable) into digital signals that can be used by devices on your local network.
On the other hand, the router is responsible for distributing the signal generated by the modem to several devices at once. So, even though the modem is directly connected to the internet, without a router, you can only connect one device to the modem. The router allows several devices to share the internet connection from the modem more efficiently.
Nowadays, many ISPs provide both a modem and a router in one device, often referred to as a modem-router. With this device, you can get an internet connection and WiFi without having to buy a separate router. However, having a separate router is often more flexible because you can choose it with features that suit your needs.
Routers are essential devices in modern digital life. Imagine if you only rely on a modem without it, maybe only one device can connect to the internet at a time.
With this access, the internet network at home becomes more practical because all family members can use the internet simultaneously. In addition, this access also maintains the security of your network to keep it safe from external threats.
So, if you are just planning to install WiFi at home, make sure you understand its important role and choose a device that suits your needs.
