Computer networks connect different computers all over the world. This is done mainly to share or transfer data and other important information. While some directly transfer the data, others do so by rerouting the information with the help of virtual private networks, or VPNs. Routers are the main devices required in order to transfer data files over the computer network. They direct the data traffic on the network and help the data files reach the destination from the source. They are analogous to the roads which help vehicles travel from one place to another. Different routers form a sort of network and help send the data from the router to router with great ease. Some routers make use of optical fibers for the transportation of data as well. Optical fibers are indeed considered as the future of data transfer.

Components of a router

A router has different components which may also be considered as its different planes. The different planes of a router are as follows:

  • The control plane is the first basic plane of a router. A table is maintained of the different routes along which the particular data file can be transferred.
  • The router uses predefined routes called static routes. The router also learns new routes called dynamic routes. Information about both these routes is then clubbed together to get the final route.
  • The second plane that forms a router is the forwarding plane. This plane is used in order to forward the data from one system to another.
  • The forwarding plane uses the routes established by the control plane in order to transfer data files.

Apart from the wired transaction and transfer via optic fibers, wireless connections are also available. In this case, transportation takes place via infrared radiations, Bluetooth or other wireless media. The wireless transfer has the potential to replace all other transfer media in the world according to many experts due to the advancement of technology. Wireless connectors are easy to use and much easier to set up. The numerous wiring cam sometimes tends to confuse many people. 

A router is a device that can be used at homes as well as in the offices. These devices ensure the security of the network and data files to a large extent. Encryption is one such algorithm used to secure data. Port forwarding has greatly improved with the new age devices available and facilitated several individuals. This includes local port forwarding as well as remote port forwarding or forwarding too far off places. A router can be bought from brick and mortar shops or can be purchased online. If any individual is on the lookout for a router, whether for personal home use or office use, they can easily seek it.

However, when you go out to look for a router, you must ensure that you are choosing the right one. You must enquire well and go as per your budgetary requirements if you want to have a good internet connection that functions smoothly.
