A crossover cable is a cable that maps all output signals on one electrical connector to the input signals on the other connector, allowing two electronic devices to perform full-duplex communication. Most commonly, the term refers to the Ethernet crossover cable, but other cables follow the same principle. It also allows devices to communicate without a switch, hub, or router. Cross-Over cables are used to connect two computers directly through NICs without the use of a Hub or Switch or to uplink two or more hubs, switches or routers. The Pins of the RJ-45 Connectors at both ends of a cross-over cable are connected as follows:

White/Orange Pin 1 ----------- Pin 3 White/Green
Orange Pin 2 ----------- Pin 6 Green
White/Green Pin 3 ----------- Pin 1 White/Orange Pin
Blue Pin 4 ----------- Pin 4 Blue
White/Blue Pin 5 ----------- Pin 5 White/Blue
Green Pin 6 ----------- Pin 2 Orange
White/Brown Pin 7 ----------- Pin 7 White/Brown
Brown Pin 8 ----------- Pin 8 Brown
Only two pairs of wires in the eight-pin RJ-45 connector are used to carry Ethernet signals. Both 10BASE-T and 100BASE-T use the same pins, a crossover cable made for one will also work with the other.
