Yes that is when your accessing the pc throught the network places in the windows environment.
Now keep in mind you will want to buy yourself a Router, or Switch to be able to connect more then just the 2 computers together.
at that point you will remove the crossover cable and put it away until you need it one day, because from each PC to the router or switch you will need a standard network cable.
We are here for you when you get that far. Get yourself some computers and your all set.
Best regards,
