Do you know what RJ45 connector is?

A brief introduction of RJ45 Connectors

The 8Pins RJ45 connector is a standardized interface which often connects a computer to a Local Area Network (LAN). This type of connector was originally developed for telephone communications but is now used in a range of networking applications. The abbreviation “RJ45” stands for Registered Jack-45. Registered Jack specifications are related to the wiring patterns of the jacks, rather than their physical characteristics. The term RJ45 has also come to refer to a range of connectors for Ethernet jacks. An 8 Position and 8 Contact connector, called an 8P8C, is a modular jack for telecommunication cables. It is also informally referred to as an RJ45.
