Why does the VM software I installed provide 4 virtual network connections?

How are these multiple VM network connections typically used, and what has to be configured differently for each?

    6.If this virtual machine was converted from a physical system, verify that there are no hidden network adapters present.

    VirtualBox allows you to configure up to 8 virtual NICs (Network Interface Controllers) for each guest vm (although only 4 are exposed in the GUI) and for each of these NICs you can configure:

    VM's have NIC's that connect to virtual switches that are then assigned physical ports., most generally 6 nics per host
    1 port for management network.
    2 ports for the guests,
    2 ports for iSCSI / NFS
    1 Port for vMotion

      I'm not sure I'm technical enough to relate to why you would want to be able to do all this - what type of applications or uses require such connectivity on a single machine ?

    VM software usually sets up network connections for network adapters that are installed on your computer. LAN and wireless are configured same as host OS.
