Cabling

Difference between straight through, crossover, and rollover cables:

Straight through:

      Straight through cables, the wires connect to the same pins on either side of the cable.These cables are primarily used for connecting unlike devices like router to switch, computer to switch, hub to switch etc.

Cross over:

     Cross over cables are similar to straight through cables, except that they have pairs of wires that crisscross. This allows for two devices to communicate at same time. The cables are primarily used for connecting like devices.

Roll over cables:

    Roll over cables essentially have one end of the cable wired exactly opposite from the other.This usually connect a device to a router or switch’s console port.
