WiFi Router Functions And How It Works and Types

WiFi Router- A router is a device that allows multiple devices to connect to the internet. In addition, another router function is to manage traffic between networks by forwarding data packets to the destination IP address.

Today, routers are essential devices in the office, cafe, or home. With a router, you can create your own WiFi network. Devices that require an internet connection, such as: laptops, smartphones, and tablets, can perform their functions optimally.

Router Functions

1. Connecting the Device to the Internet

The main function of the router is to connect the device to the internet network. Especially for WiFi routers, this router can send data or internet packets from the modem to the device via IP Address. That way, connected devices can access the internet.

Routers can distribute internet data to each device or gadget. Currently there are many types of devices that you can connect to a router, for example: laptops, PCs, smartphones, tablets, to smart TVs.

2. Spread WiFi Signal

The router’s job is to convert the signal from the modem into a WiFi radio signal. This is the function of the router, which is to channel internet access to all areas of the room. That way, every device that requires WiFi can access the internet via a WiFi wireless signal.

For buildings that are large or have two floors, usually two routers are installed. The goal is to spread the WiFi signal more evenly. Otherwise, there will be many corners of the room that are not covered by a WiFi signal (Blank Spot). To know more about business art and entertainment you can visit this site festivaldelladriatico

3. Connect Multiple Devices

Routers can transmit data from one network to another. It works like a bridge so that every connected device can communicate with each other. Routers can connect devices with two different networks.

For example, a wireless router can connect a laptop with a radio signal or a UTP (Unshielded Twisted Pair) cable. This way, you can connect the router to many different types of devices.

4. Connecting the Network to DSL

The last function of the router is as a liaison between the network and the DSL (Digital Subscriber Line) or DSL Router. DSL Router functions as a firewall to protect data and prevent cyber threats posed from the internet network.

This function allows the router to block suspicious data traffic. In essence, you can block IP addresses with a router. In addition, DSL can also prevent a broad cast storm that causes network performance to slow down.

How Routers Work

How the router works is actually very simple. The router can be likened to an air traffic controller (ATC – Air Traffic Controller) and data packets or the internet as the plane. Every plane has its own purpose. Every plane needs guidance in order to reach its destination as efficiently as possible.

This is where routers work. In the same way as air traffic controllers, routers ensure that each aircraft is able to reach its destination without getting lost and experiencing disturbances on the way. Routers help direct data packets to get to their intended IP address effectively.

To route data packets effectively, routers use an internal routing table, which lists paths to various network destinations. The router reads the header of the power packet and determines where it goes.

The router then uses the routing table to figure out the most efficient or fast path to that destination. After that, the router forwards the next network packet on the path.
