crossover cables must be used between 2 devices from the same level like (pc & pc - Pc & router - router & router)
but strait through cable used between 2 different levels like (pc & switch - router & switch )
Match up the two ends of the cable. Look closely at the color coding of the pins at both RJ-45 connectors. If the same colors are used in the same pin positions then the cable is a straight-through cable. If they are reversed at both ends then it is a cross-over cable.Sometimes the cable will be marked that way on the outside covering of the cable. Look for the words "cross-over cable".
No, it does not matter if the cable wires cross over. It should not cause any problems if they cross over. However, there are several products that allow them to cross over to add on benefits.
In general, no, you would not use a cross-over cable to connect a hub/switch/router to a PC. This is because the device itself has cross-over circuitry built into it, and if you used a cross-over cable you would be reversing that process. The net effect is that the transmit signal would connect to another transmit signal, when it should be connected to a receive signal.
we used cross over cable ,coz cross over cable has two ends one end for tranmitting data and one end for receiving data ,thats why cross over used in peer to peer data connection.
The difference between a cross cable and a state cable is that a cross cable, or crossover cable, is used specifically to connect two of the same devices.

Cross-Over
A cross-over cable directly connects two PC's without the need for a device such as a switch. The cross-over cable works by having one end's pins in a standard order and the other end swaps the transmit and receive wires. RJ-45 UTP CABLE IS ACTUALLY USED.
straight cable is needed when connecting two computer periperhals. A cross over is used when connecting a computer to a network hardware (router, swirch, etc..)
