Lan card to lan card, what cable to use?

Question

hello,
in the k7n420, have a lan card, well, its not a card, but its also lan, ethernet.  my friend says that theres this cable that would allow to connect lan card to lan card without a hub, something called cross cable.  you guys heard anything about this?
thanks,

Technically, all hubs have that feature, because what a cross-over does is simulate what a hub naturally does. You may be getting confused with the uplink connection, I think.
Wow...yah, you are correct on that.  I don't know what I was thinking.

if i were to follow the color codes exactly as the diagram, then i have to fix the first terminal first then twist the wires for the second terminal?
why is that that my cable's color order is not the same, arent cables standard?
Pre-made cables sometimes use a different color code.  I don't know the reason for this.  If you want to make a crossover cable out of your cable then I would cut BOTH ends off and wire it as shown in the diagram.

and one more thing, if i were to rearrange the wires, are the wires specially made for "receving" or "transmitting"? or is it just color coding so you'd know where to pin it?
and since i did not folow exactly the diagram, because color order was not the same, i used common sense and just followed the order. could my order be incorrect, when i connect the cable, my lan lights up and my sister's laptop also lights up, when i look at the network connections, i get the lan status just like the dial-up connection status for internet.
The wires are not specifically made for sending or receiving.  However, you should follow the color code in the diagram because it follows industry standards.  There is electrical "crosstalk" that happens between the twisted-pair wires within the Category 5 cable.  The cross-talk is minimized when using the color code in the diagram.  The manufacturer of your cable chose a different coding scheme, but I am sure that you will find the same Rx and Tx patterns in the colors that they used are the same as the color code in the diagram.  If you used a different code, using common-sense, and the cable is working then I wouldn't worry about it.  The biggest problem occurs when an incorrect color code is used and the cable is a longer length.
