RJ-45
The RJ45 is a physical interface
commonly used to connect networks of structured cabling (categories 4, 5, 5e and 6). RJ is a acronym English of Registered Jack which in turn is part of the Code of Federal Regulations U.S. . It has eight "pins" or electrical connections, which normally are used as ends of cables twisted pair .
is commonly used standards such as
TIA/EIA-568-B , which defines the layout of the pins or wiring pinout .
A common application is its use in network cables
Ethernet, which are commonly used 8-pin (4 pairs). Other applications include terminations phones (4-pin or 2 pairs), for example in France and Germany, other services network as ISDN and T1 even RS232.

For all work on any network cables, it follows a standard when making connections. The two ends of the cable have RJ45 connector with the colors in the order shown in the figure. Pin 1 is the left when looking at the plug from the front, with the safety tab facing up:

The most widely used scheme in practice is the 568B. There is another different distribution, which would be the 568-A. There is no difference in connectivity between 568B and distribution distribution 568.
Although all the threads usually attached to the Ethernet communications are needed only pins '1 and 2 'and '3 and 6', the other being used for telephony (
