What is the most common type of network cabling?

The most commonly used types of network cable are the twisted pair, coaxial, Ethernet cross over, and fiber optic. The unshielded twisted pair (UTP) cable is used in many Ethernet networks. It has four pairs of wires that are housed inside of the lining of the cable.

RJ45 CONNECTERS USED IN CROSSOVER CABLE

how to build a cross over cable by seeing below image you can make a crossover cable tools used to make it are a crimping tool and a analyzer to check the cable is working from both end

UTP (UNSHIELDED TWISTED PAIR CABLE)

STP(SHEILDED TWISTED PAIR CABLE)

on left figure you will see staright through wiring scheme and in right cross over wiring scheme

HERE YOU CAN COMPARE IN TWO DEVICES WHICH CABLE TO USED IF SAME DEVICES ARE USE CROSS OVER CABLE AND IF DIFFERENT DEVICES USE STRAIGHT THROUGH CABLE
BUT IF YOU PLACE WRONG CABLE NO WORRY SWITCH OR ROUTER INTERNALLY MAKE A WRONG CABLE TO ITS USE AND MAKE IT RIGHT.
