Straight through is the most common type and is used to connect computers to hubs or switches. They are most likely what you will find when you go to your local computer store and buy a patch cable.
Crossover Ethernet cable is more commonly used to connect a computer to a computer and may be a little harder to find since they aren’t used nearly as much as straight through Ethernet cable.
