This NIC (Network Interface Card) could be used in a computer if you want to have another network if you don't want to use the build in LAN Card. For me, i will be using this NIC for my firewall. This will be used as my WAN or LAN, depending on that will be the designation of this card. Other find it so tricky or difficult to identify or understand about this thing, but it is really simple to know these things if you really want to learn.
