text: what tools do i need to add on a second computer? i have a second computer that is not being used and i want to hook it up to my current one.  what i am trying to find out is what cables do i need to hook it up???  can someone please tell me what all i need to hook up this other computer???  i guess that will also fall under the network.  thank you if both machines have nic cards and you do not have a ethernet hub or router you can use a crossover ethernet cable also kown as rollover ethernet cable.
