In networking, there are two main types of cables used. If you’re a technical writer documenting networks, you should be familiar with these basic terms.
Straight-Through Cable
This is (usually) a CAT-5 network cable used between a PC and a network hub. The eight terminals on both ends of the cable (called RJ-45 jack) are wired such that both ends transmit and receive signals through the same terminals. This is also called 568A wire order.
Here is a great illustration that describes this arrangement (where GREEN wires transmit data and ORANGE wires receive data): http://suborbit.com/docs/xover.html
Crossover Cable
This is (usually) a CAT-5 network cable used between a PC and another PC. The eight terminals on both ends of the cable (called RJ-45 jack) are wired such that one end transmits the network signal (568A wire order ) but the other end receives it (568B wire order).

NOTE: The only difference between these two types of cables is the way GREEN and ORANGE wires are connected. the BLUE and BROWN wires are the same in both.
