Key Takeaway - A crossover cable allows you to connect two older computers or switches directly to one another and is wired differently on one side than on the other. Most modern-day switches and computers can automatically sense the type of cable plugged-in and the type required, and make the adjustment automatically. An RJ45 connector is the connection used for Cat5 and Cat6 cables, and an RJ11 cable is used for most phone connections.
