Q

Which of the following is not true of crossover cables?
A. They are a type of twisted pair cabling.
B. They reverse the sending and receiving wire pairs.
C. The are used to connect hubs.
D. Both ends of a crossover cable are wired according to the TIA/EIA 568B standard.

A

D. One end of a crossover cable is wired according to the TIA/EIA 568B standard; the other is wired according to the TIA/EIA 568A standard. This is what crosses the wire pairs and enable two hubs to communicate without colliding.
