Ethernet cards
What is the point in buying an ethernet card?
I am referring to my previous thread about connecting 2 PC's to the same internet connection and apparently I need to get a cross over cable and an ethernet card but I fail to see why because my computer already appears to have a slot which look identical to the slot on an ethernet card so why should I go and buy one when it looks quite complicated and fiddly to install from what I have seen with unscrewing the whole desktop etc.
