Shared Networking. Select this option to enable the Network Address Translation (NAT) feature for the virtual machine. In this case, your virtual machine will share whatever network connection is currently used by the host computer.
See Shared Networking to learn how to configure this type of networking.
Bridged Networking. Select this option to allow the virtual machine to access the local network and Internet through one of the network adapters installed on the host computer. In this case, the virtual machine is treated as a stand-alone computer on the network and should be configured in the same way as a real one. You can choose the physical adapter where the virtual machine adapter will be bridged in the list below the Bridged Networking option.
See Bridged Ethernet Networking to learn how to configure this type of networking.
