Plug an Ethernet cable into the networking port located on the back of each computer, including the server. To take advantage of the gigabit speeds, each computer will need to have a gigabit-capable networking card. You can check to what kind of card a Windows-based computer has by right-clicking on “My Computer,” clicking “Properties,” then the “Hardware” tab, followed by “Device Manager.” Under “Network Adapters” the card type will be listed. If any of the computers don’t have one of these cards, one can be purchased and easily installed by the average computer user.
