How can I connect my laptop to my desktop so I can transfer files?

The best way to connect your laptop to your desktop is to use the computers' built-in networking capabilities. This can be done by connecting the computers via an Ethernet or wireless network connection. An Ethernet connection requires that each computer has an Ethernet port, which looks like a wide phone jack. If you are connecting two computers directly, you need to use an Ethernet crossover cable. If you are connecting both computers to a network hub, you should use a straight-through Ethernet cable to connect each computer to the hub.
