RJ refers to which general category of connectors?

• A. RJ
• B. Registered Jack
• C. RJ11
• D. RJ45

Answer: (B)

RJ stands for Registered Jack, the broad family of modular connectors standardized for telecommunication and networking peripherals. This category defines the interface so equipment from different manufacturers can interoperate. RJ11 and RJ45 are specific types within that family, each with its own pin count and wiring schemes. The reason this is the best answer is that the general category name reflects the standardized family itself, while the numbered variants are particular implementations within that family. For context, the Registered Jack standards ensure compatibility and specify both the physical connector and its typical use, such as RJ11 for telephone lines and RJ45 for Ethernet.
