Explanation
When connecting two devices of the same type (e.g., two routers, two switches, or two DTEs), a crossover cable is required. This cable swaps the transmit and receive pairs to allow direct communication between devices without the need for an intermediate device like a switch. Straight-through cables are used to connect different types of devices (e.g., PC to switch). Rolled cables are used for console access. USB Type A to B cables are typically used for peripheral device connections, not networking.
