The Null modem Cables are the example of the crossover cables.The pairs(Tx and Rx lines) will be crossed which means pin 1 & 2 of the plug on one end are connected with pin 3 & 6 of the plug on other end, and vice versa (3 & 6 to pin 1 & 2).Crossover cable is used to connect two computers or Ethernet devices directly together without a hub.This is a simple physical connection used in printers, computers and other network interfaces.The straight-through wiring cables are mostly used for connecting PC/NIC card to a hub.These cable wires are in the same sequence at both ends of the cable, which means that pin 1 of the plug on one end is connected to pin 1 of the plug on the other end (for both standard – T568A & T568B).
In general, the Ethernet cables used for Ethernet connections are “straight-through cables”. It is also known as color-coding techniques. There are three types of wiring techniques to construct the Ethernet cable.
