vpn 1Virtual Private Networking or better known as VPN is a technology that allow users to connect two Networks using the internet and make them operate as if they are in one physical location. This will make businesses operate more easy, which means both ends are now in full communication and they can perform any task that seemed impossible before, such as: access to shared files and folders over LAN, connect to Database directly, print to each other's printer, monitor operations. This technology has evolved to be the most secure way of connecting two or more points with standard encryption of 128bit or 256bit. Both ends can work effectively and securely.
