which type of cable has opposite pin assignments on each end of the cable
A crossover cable has opposite pin assignments on each end of the cable. In a standard Ethernet cable (straight-through cable), the pin configurations at both ends are the same. However, in a crossover cable, certain pairs of wires are crossed or switched to allow for direct communication between two similar devices, such as connecting two computers without a switch or router in between. The specific pin assignments that are crossed in a crossover cable typically involve the transmit (TX) and receive (RX) pairs. This configuration allows one device's transmit signals to connect directly to the other device's receive signals, facilitating communication between the two devices. Crossover cables are commonly used for connecting similar devices, such as computer to computer or switch to switch.
