How Does a Router Works?
In simple words, a router links devices in a network by forwarding information packets between them. This information can be delivered between gadgets, or from gadgets to the internet. The router performs this through allocating a local IP address to each of the gadgets on the network. This makes sure that the information packets land in the proper destination, instead of disappearing inside the network.
Now l shall narrate the whole work in a different way. Let us assume this data as a courier package. So, this courier package requires a delivery address so that it can reach the genuine receiver. Your local computer network is similar to a suburban road. So, simply knowing this location in the universe (i.e. the World Wide Web) certainly is not enough.
This package may easily reach an inappropriate house with reasonably limited data. Therefore, the router ensures that every single location (gadget) has a distinct number to ensure that the package reaches the proper address.
If you want to return the information to the sender, or perhaps want to send out your personal package, your router also performs this job. Even though it deals with every single packet separately but it performs this so swiftly that it seems instantaneous. It does the same process also when multiple gadgets send data at the same time.
Not only a router links up multiple gadgets to the internet, but also it connects multiple gadgets to one another. Yet you can generate a local network of computers and also other gadgets without the internet. This permits you to transfer and share data with particular gadgets in a network such as printers, scanners, and game consoles.
A local network can work without the presence of the internet or a modem, however, it cannot works without a router.
