RJ45 connector commonly used for network cabling in Ethernet connections.

RJ45 stands for Registered Jack 45. 

It is an 8-pin connector that interfaces devices with a local area network (LAN).
 
It terminates the end of an Ethernet cable, allowing it to connect with network hardware like modems, routers, or computers.
 
RJ45 connectors are used in homes, offices, data centers, and industrial settings. 

They follow wiring standards T568A or T568B for twisted-pair cables. 

They have eight contact points, often gold-plated for better data transmission. 

The connectors come in different categories, such as Cat5e, Cat6, and Cat7, depending on the cable type.
