What does RJ-45 connector commonly connect?

• A. A port used by fiber optic cables to connect to devices
• B. A connector for twisted-pair Ethernet networks
• C. A wireless coax interface
• D. A universal serial bus port

Answer: (B)

RJ-45 is a modular connector designed for copper twisted-pair Ethernet cables. It carries Ethernet signals over cables like Cat5e or Cat6 and plugs into network ports on devices such as computers, switches, and routers. That makes it the standard way to link devices in a wired Ethernet network. It isn’t used for fiber optics (which use connectors like SC or LC), nor for wireless interfaces, and it’s not a USB port. So the connector is best described as a connector for twisted-pair Ethernet networks.
