What is the primary function of RJ45 connectors?

The primary function of RJ45 connectors is to facilitate computer networking, specifically through Ethernet connections. RJ45 connectors are the standard connector type used for making connections within local area networks (LANs). They are designed to connect Ethernet cables, which carry data between devices such as computers, switches, and routers within a network.

RJ45 connectors have eight pins that allow for the transmission and reception of data, enabling fast and reliable communication between networked devices. This makes them crucial for establishing the backbone of many LAN infrastructures, supporting various networking protocols and data transfer rates.

While there are other types of connections used for different applications—such as RJ11 for telephone lines, which is wired for two lines—RJ45's primary application remains in the domain of computer networking, particularly for Ethernet communications.
