What is a Router in Networking and How it Works?

What is a Router?

In short, the Router creates a network between computers in your home, while your modem connects it to the Internet. When you connect to WiFi, you connect to your router, which is responsible for transmitting traffic between the internet and your computer. Given the seeming complexity of such devices, many Internet Service Providers (ISPs) now offer a unified device that combines Modem and Router.

What Does it Do?

A router can connect multiple networks and route network traffic between them. Your router on your home network is the bridge between an Internet connection and your private local network. In addition, routers have a Switch that connects different devices and has a radio to access WiFi.

The router is between your internet connection and your local area network. It allows you to connect several devices to the Internet at the same time over the same physical Internet connection and communicate with each other on the local network. It also provides protection for all your connected devices. Finally, it monitors which data is transmitted to which device on the network.

What is ADSL Modem Router?

When you purchase services from any Internet Service Provider, you will receive a device, the ADSL Modem.

The ADSL Modem used for Internet access also has built-in additional components such as a Switch, WiFi.

This device can interact with your ISP to provide Internet access and allows you to surf.

Combined devices that host multiple services have advantages, but they also have disadvantages. Instead of using two separate devices, the device provided by the ISP can be used. However, the use of a single device is not recommended as it may cause performance problems in a large network. For example, a company does not use a single device that performs all tasks. Instead, more advanced network devices are preferred.

As a result, you can purchase your own device instead of opting for a paid device from your ISP. Because the performance of these dedicated devices is targeted only to home users, it may cause future problems in your evolving network topology.

Also, the device provided by your ISP may not have the latest technologies, such as 802.11ac and 5Ghz Wi-Fi.

So if you are going to purchase an ADSL Modem or Router yourself, you should ensure that it includes the latest technologies.
