It all depends on a number of things. The first part is, do you want the computer to be on the same network (connecting to the internet)? If so, plug it into the router/switch/hub with an RJ-45 (most people just call it an Ethernet cable). But if you want two computers to be able to share files (connect to each other) on a "simple network" then it might depend on what kind of hardware you have. If you have a parallel slot, use that if you just have two computers. If you don't have a parallel slot then you should hopefully have some sort of Network Interface Card (NIC) and there will be an RJ-45 slot. If you have Windows, you'll have to do a setup with the local network wizard (or something like that). With Linux or Mac, use Samba. Hope this helps, and hope I didn't mess something up. -Zofc
Cat5 or Cat6 cables with RJ45 connectors.
Use a cross-over cable.
Crossover Cable
a Crossover Cable.
A Crossover Cable is used to connect 2 PCs (when a hub or switch is not used) to make the simplest network of all. (6th Edition, Page 852)
A crossover cable.
All the components needed to connect 2 computers together are two Ethernet cards, a network switch and 2 Ethernet cables. Alternatively a single USB transfer cable can be used for simple file transfers.
All you need is an ethernet cable and connect them together. If you already have a router then just connect the two to the network.
None. You need a network card and cable to connect them. The cable is called CAT 5.
Lan Card provides a port for a network cable to connect the pc to a network.. LAN : Local area network or Ethernet Card and Network Card
You would want to use get a crossover cable.
If you are using a crossover cable, simply assign static IP's to each machine (192.168.0.2 and 192.168.0.3). If using regular network cable, you will need to use a network switch or hub to connect them together, still using the static IP's for each machine.

If you don't have at least two wireless adapters for your pcs, yes you have to have a network cable in order to connect two pcs.
