RJ stands for which of the following in the context of connectors?

Explanation:
RJ in connectors naming represents a Registered Jack, a standardized family of modular jacks. The number that follows identifies the specific variant of that registered jack, with RJ11 being the common telephone-line connector. Some materials describe this variant as “Registered Jack Function 11” to convey the exact type, so choosing that phrasing aligns with how the variant is identified. The general term alone doesn’t specify which jack type, and other variants like RJ45 refer to different connectors, so emphasizing the exact variant (11) makes this the best match.
