What does the RJ45 connector typically connect to?

The RJ45 connector is primarily used to connect network devices through Ethernet cabling, and specifically, it is commonly associated with CAT 5 (Category 5) and higher category Ethernet cables. These cables are designed for data transmission in local area networks (LANs) and are crucial for connecting computers, routers, switches, and other networking equipment. The RJ45 connector consists of eight pins that facilitate the sending and receiving of data over these cables.

In comparison, fiber optic cables utilize different types of connectors, which are not compatible with RJ45 connectors. VGA connectors are used for video display but are not related to network connections. USB devices use USB connectors, which also do not connect through an RJ45 interface. Thus, the CAT 5 Ethernet cable is the correct connection that corresponds to the use of an RJ45 connector in networking scenarios.
