Let's talk about Network Bridge today and see what it is and what it is used for in order to remove some confusion about it and discover the dynamics of networks between computers that are always interesting and useful to know. Network bridge is called the linking mechanism between two different separate networks.
As already explained in the technical article "How we connect to the internet and why with the same public IP address"> If you have two routers in an office or at home, you can imagine a situation where they are not connected to each other, one it is wireless wifi while the other is an ethernet router from which cables leave, one which is also connected to the internet and the other instead which is only a private network without internet access. In such a situation, devices connected to the wifi network cannot see and speak to computers connected to the cable network .
The Network Bridge creates this connection and allows you to join the two networks.

With Windows 10, Windows 7 and Windows 8, (not the Home versions) if you use a computer connected to two different networks, one wifi and one via cable and if you are not using internet sharing, you can create the network . With the Network Bridge, all computers connected to network A can "see" the computers connected to network B and the computer that is connected to both networks acts as an intermediary.
Only one network bridge can be created on one computer, but the Bridge can handle an unlimited number of network connections.
To create a Network Bridge in Windows, open the Network Connections in the Control Panel (or go to Start -> Run and type the command ncpa.cpl ). In the network adapter settings screen, select the two networks (at least two) that you want to bridge. click on one, hold down the CTRL key and then click on the other. After selecting them, right click on one of the two and create the network bridge. After a certain upload, a third connection appears which becomes the main one and which links the two connections together.
As you can guess, the network bridge is used only in very particular and specific cases. Very often the network bridge is confused with the technique of amplifying the wifi internet signal from a computer. Having two wifi network cards on a computer, if you want to repeat the signal coming from a wireless router, you don't have to create the network bridge but share the internet on the other wifi card.

Be careful not to create a bridge between an Internet connection and a private network connection because the unsecured connection makes your network accessible to anyone on the Internet.
As an alternative to the network bridge, you can join two networks in one by following the guide to increase the wifi signal with two wireless routers connected together
