Rj45 connectors have been used for phone and ethernet connections for a long time but their original development.

A good way of remembering how to wire a crossover ethernet cable is to wire one end using the t 568a standard and the other end using the t 568b standard.
Ethernet has been taking over the world for the last few decades.
Ethernet cable color coding exists as part of the industry standard t568a t458b.
These wires are twisted into 4 pairs of wires each pair has a common color theme.
A good way of remembering how to wire a crossover ethernet cable is to wire one end using the t 568a standard and the other end using the t 568b standard.
Internal cable structure and color coding inside the ethernet cable there are 8 color coded wires.
There are two color code standards tia eia 568a 568b for making a working network cable.
Another way of remembering the color coding is to simply switch the green set of wires in place with the orange set of wires.
If you are using utp cat 5 cable than you have to follow cat5 color code in order to make a working cable.
Knowing how to crimp rj45 cat6 cables as well as being familiar with the cat6 crimping color code is critical for an electrician network technician engineer and anyone interested in installing an ethernet cable.
Alter cables at your own risk.
As there are 8 wires in every utp cables you have to follow color coding standard on where to place each wires at rj 45 connector.
Standards exist so technicians can know how the cable should work and can reliably alter the cable when necessary.
