What is crossover cable?
It’s a type of computer cable where some of the strands inside are “crossed over” compared to a “straight through” cable. You only need a crossover cable if you are connecting a computer directly to another computer. If you are connecting a computer to any other device like a switch, or a router, then you use a straight through cable, which are easier to find and cheaper. You can google for a crossover cable and it will show you a picture of which pins are crossed over.
